Method Details

getOutputTarget

public Object getOutputTarget()

Description copied from class: JsonGenerator

Method that can be used to get access to object that is used as target for generated output; this is usually either OutputStream or Writer, depending on what generator was constructed with. Note that returned value may be null in some cases; including case where implementation does not want to exposed raw source to caller. In cases where output has been decorated, object returned here is the decorated version; this allows some level of interaction between users of generator and decorator object.

In general use of this accessor should be considered as "last effort", i.e. only used if no other mechanism is applicable.

Overrides:

getOutputTarget in class JsonGenerator

Returns:

Output target this generator was configured with

getOutputBuffered

public int getOutputBuffered()

Description copied from class: JsonGenerator

Method for verifying amount of content that is buffered by generator but not yet flushed to the underlying target (stream, writer), in units (byte, char) that the generator implementation uses for buffering; or -1 if this information is not available. Unit used is often the same as the unit of underlying target (that is, `byte` for OutputStream, `char` for Writer), but may differ if buffering is done before encoding. Default JSON-backed implementations do use matching units.

Note: non-JSON implementations will be retrofitted for 2.6 and beyond; please report if you see -1 (missing override)

Overrides:

getOutputBuffered in class JsonGenerator

Returns:

Amount of content buffered in internal units, if amount known and accessible; -1 if not accessible.

writeFieldName

public void writeFieldName(String name)
                    throws IOException

Description copied from class: JsonGenerator

Method for writing a field name (JSON String surrounded by double quotes: syntactically identical to a JSON String value), possibly decorated by white space if pretty-printing is enabled.

Field names can only be written in Object context (check out JSON specification for details), when field name is expected (field names alternate with values).

Specified by:

writeFieldName in class JsonGenerator

Parameters:

name - Field name to write

Throws:

IOException - if there is either an underlying I/O problem or encoding issue at format layer

writeFieldName

public void writeFieldName(SerializableString name)
                    throws IOException

Description copied from class: JsonGenerator

Method similar to JsonGenerator.writeFieldName(String), main difference being that it may perform better as some of processing (such as quoting of certain characters, or encoding into external encoding if supported by generator) can be done just once and reused for later calls.

Default implementation simple uses unprocessed name container in serialized String; implementations are strongly encouraged to make use of more efficient methods argument object has.

Overrides:

writeFieldName in class GeneratorBase

Parameters:

name - Field name to write

Throws:

IOException - if there is either an underlying I/O problem or encoding issue at format layer

Overrides:

writeStartArray in class JsonGenerator

Parameters:

public void writeStartObject(Object forValue)
                      throws IOException

Description copied from class: JsonGenerator

Method for writing starting marker of an Object value to represent the given Java Object value. Argument is offered as metadata, but more importantly it should be assigned as the "current value" for the Object content that gets constructed and initialized.

Object values can be written in any context where values are allowed: meaning everywhere except for when a field name is expected.

Overrides:

writeStartObject in class GeneratorBase

Parameters:

forValue - "Current value" to assign for the Object context being created

Throws:

IOException - if there is either an underlying I/O problem or encoding issue at format layer

 int size)
                      throws IOException

Description copied from class: JsonGenerator

Method for writing starting marker of an Object value to represent the given Java Object value. Argument is offered as metadata, but more importantly it should be assigned as the "current value" for the Object content that gets constructed and initialized. In addition, caller knows number of key/value pairs ("properties") that will get written for the Object value: this is relevant for some format backends (but not, as an example, for JSON).

Object values can be written in any context where values are allowed: meaning everywhere except for when a field name is expected.

Overrides:

writeStartObject in class JsonGenerator

Parameters:

forValue - "Current value" to assign for the Object context being created

size - Number of key/value pairs this Object will have: actual number of entries written (before matching call to JsonGenerator.writeEndObject() MUST match; generator MAY verify this is the case (and SHOULD if format itself encodes length)

Marker can be written if the innermost structured type is Object, and the last written event was either a complete value, or START-OBJECT marker (see JSON specification for more details).

Specified by:

writeEndObject in class JsonGenerator

Throws:

IOException - if there is either an underlying I/O problem or encoding issue at format layer

public void writeString(String text)
                 throws IOException

Description copied from class: JsonGenerator

Method for outputting a String value. Depending on context this means either array element, (object) field value or a stand alone String; but in all cases, String will be surrounded in double quotes, and contents will be properly escaped as required by JSON specification.

Specified by:

writeString in class JsonGenerator

Parameters:

text - Text value to write

Throws:

IOException - if there is either an underlying I/O problem or encoding issue at format layer

writeString

public void writeString(Reader reader,
 int len)
                 throws IOException

Description copied from class: JsonGenerator

Method for outputting a String value. Depending on context this means either array element, (object) field value or a stand alone String; but in all cases, String will be surrounded in double quotes, and contents will be properly escaped as required by JSON specification. If len is < 0, then write all contents of the reader. Otherwise, write only len characters.

Note: actual length of content available may exceed len but can not be less than it: if not enough content available, a JsonGenerationException will be thrown.

Overrides:

writeString in class JsonGenerator

Parameters:

reader - Reader to use for reading Text value to write

len - Maximum Length of Text value to read (in chars, non-negative) if known; -1 to indicate "read and write it all"

Throws:

public void writeString(char[] text,
 int offset,
 int len)
                 throws IOException

Description copied from class: JsonGenerator

Method for outputting a String value. Depending on context this means either array element, (object) field value or a stand alone String; but in all cases, String will be surrounded in double quotes, and contents will be properly escaped as required by JSON specification.

Specified by:

writeString in class JsonGenerator

Parameters:

text - Buffer that contains String value to write

offset - Offset in buffer of the first character of String value to write

len - Length of the String value (in characters) to write

Throws:

writeString

public final void writeString(SerializableString text)
                       throws IOException

Description copied from class: JsonGenerator

Method similar to JsonGenerator.writeString(String), but that takes SerializableString which can make this potentially more efficient to call as generator may be able to reuse quoted and/or encoded representation.

Default implementation just calls JsonGenerator.writeString(String); sub-classes should override it with more efficient implementation if possible.

Overrides:

writeString in class GeneratorBase

Parameters:

text - Pre-encoded String value to write

Throws:

IOException - if there is either an underlying I/O problem or encoding issue at format layer

writeRawUTF8String

public void writeRawUTF8String(byte[] text,
 int offset,
 int len)
                        throws IOException

Description copied from class: JsonGenerator

Method similar to JsonGenerator.writeString(String) but that takes as its input a UTF-8 encoded String that is to be output as-is, without additional escaping (type of which depends on data format; backslashes for JSON). However, quoting that data format requires (like double-quotes for JSON) will be added around the value if and as necessary.

Note that some backends may choose not to support this method: for example, if underlying destination is a Writer using this method would require UTF-8 decoding. If so, implementation may instead choose to throw a UnsupportedOperationException due to ineffectiveness of having to decode input.

Specified by:

writeRawUTF8String in class JsonGenerator

Parameters:

text - Buffer that contains String value to write

offset - Offset in buffer of the first byte of String value to write

len - Length of the String value (in characters) to write

Throws:

IOException - if there is either an underlying I/O problem or encoding issue at format layer

writeUTF8String

public void writeUTF8String(byte[] text,
 int offset,
 int len)
                     throws IOException

Description copied from class: JsonGenerator

Method similar to JsonGenerator.writeString(String) but that takes as its input a UTF-8 encoded String which has not been escaped using whatever escaping scheme data format requires (for JSON that is backslash-escaping for control characters and double-quotes; for other formats something else). This means that textual JSON backends need to check if value needs JSON escaping, but otherwise can just be copied as is to output. Also, quoting that data format requires (like double-quotes for JSON) will be added around the value if and as necessary.

Note that some backends may choose not to support this method: for example, if underlying destination is a Writer using this method would require UTF-8 decoding. In this case generator implementation may instead choose to throw a UnsupportedOperationException due to ineffectiveness of having to decode input.

Specified by:

writeUTF8String in class JsonGenerator

Parameters:

text - Buffer that contains String value to write

offset - Offset in buffer of the first byte of String value to write

len - Length of the String value (in characters) to write

Throws:

IOException - if there is either an underlying I/O problem or encoding issue at format layer

writeRaw

public void writeRaw(String text)
              throws IOException

Description copied from class: JsonGenerator

Method that will force generator to copy input text verbatim with no modifications (including that no escaping is done and no separators are added even if context [array, object] would otherwise require such). If such separators are desired, use JsonGenerator.writeRawValue(String) instead.

Note that not all generator implementations necessarily support such by-pass methods: those that do not will throw UnsupportedOperationException.

Specified by:

writeRaw in class JsonGenerator

Parameters:

text - Textual contents to include as-is in output.

Throws:

IOException - if there is either an underlying I/O problem or encoding issue at format layer

writeRaw

public void writeRaw(String text,
 int offset,
 int len)
              throws IOException

Description copied from class: JsonGenerator

Method that will force generator to copy input text verbatim with no modifications (including that no escaping is done and no separators are added even if context [array, object] would otherwise require such). If such separators are desired, use JsonGenerator.writeRawValue(String) instead.

Note that not all generator implementations necessarily support such by-pass methods: those that do not will throw UnsupportedOperationException.

Specified by:

writeRaw in class JsonGenerator

Parameters:

text - String that has contents to include as-is in output

offset - Offset within text of the first character to output

len - Length of content (from text, starting at offset offset) to output

Throws:

IOException - if there is either an underlying I/O problem or encoding issue at format layer

writeRaw

public void writeRaw(SerializableString text)
              throws IOException

Description copied from class: JsonGenerator

Method that will force generator to copy input text verbatim with no modifications (including that no escaping is done and no separators are added even if context [array, object] would otherwise require such). If such separators are desired, use JsonGenerator.writeRawValue(String) instead.

Note that not all generator implementations necessarily support such by-pass methods: those that do not will throw UnsupportedOperationException.

The default implementation delegates to JsonGenerator.writeRaw(String); other backends that support raw inclusion of text are encouraged to implement it in more efficient manner (especially if they use UTF-8 encoding).

Overrides:

writeRaw in class JsonGenerator

Parameters:

text - Pre-encoded textual contents to included in output

Throws:

IOException - if there is either an underlying I/O problem or encoding issue at format layer

                       throws IOException

Helper method that is called for segmented write of raw content when explicitly outputting a segment of longer thing. Caller has to take care of ensuring there's no split surrogate pair at the end (that is, last char can not be first part of a surrogate char pair).

Throws:

IOException

writeBinary

public void writeBinary(Base64Variant b64variant,
 byte[] data,
 int offset,
 int len)
                 throws IOException,
JsonGenerationException

Description copied from class: JsonGenerator

Method that will output given chunk of binary data as base64 encoded, as a complete String value (surrounded by double quotes). This method defaults

Note: because JSON Strings can not contain unescaped linefeeds, if linefeeds are included (as per last argument), they must be escaped. This adds overhead for decoding without improving readability. Alternatively if linefeeds are not included, resulting String value may violate the requirement of base64 RFC which mandates line-length of 76 characters and use of linefeeds. However, all JsonParser implementations are required to accept such "long line base64"; as do typical production-level base64 decoders.

Specified by:

writeBinary in class JsonGenerator

Parameters:

b64variant - Base64 variant to use: defines details such as whether padding is used (and if so, using which character); what is the maximum line length before adding linefeed, and also the underlying alphabet to use.

data - Buffer that contains binary data to write

offset - Offset in data of the first byte of data to write

len - Length of data to write

Throws:

IOException - if there is either an underlying I/O problem or encoding issue at format layer

JsonGenerationException

writeBinary

public int writeBinary(Base64Variant b64variant,
 InputStream data,
 int dataLength)
                throws IOException,
JsonGenerationException

Description copied from class: JsonGenerator

Method similar to JsonGenerator.writeBinary(Base64Variant,byte[],int,int), but where input is provided through a stream, allowing for incremental writes without holding the whole input in memory.

Overrides:

writeBinary in class GeneratorBase

Parameters:

b64variant - Base64 variant to use

data - InputStream to use for reading binary data to write. Will not be closed after successful write operation

dataLength - (optional) number of bytes that will be available; or -1 to be indicate it is not known. If a positive length is given, data MUST provide at least that many bytes: if not, an exception will be thrown. Note that implementations need not support cases where length is not known in advance; this depends on underlying data format: JSON output does NOT require length, other formats may.

Returns:

Number of bytes read from data and written as binary payload

Throws:

IOException - if there is either an underlying I/O problem or encoding issue at format layer

writeNumber

public void writeNumber(String encodedValue)
                 throws IOException

Description copied from class: JsonGenerator

Write method that can be used for custom numeric types that can not be (easily?) converted to "standard" Java number types. Because numbers are not surrounded by double quotes, regular JsonGenerator.writeString(java.lang.String) method can not be used; nor JsonGenerator.writeRaw(java.lang.String) because that does not properly handle value separators needed in Array or Object contexts.

Note: because of lack of type safety, some generator implementations may not be able to implement this method. For example, if a binary JSON format is used, it may require type information for encoding; similarly for generator-wrappers around Java objects or JSON nodes. If implementation does not implement this method, it needs to throw UnsupportedOperationException.

Specified by:

writeNumber in class JsonGenerator

Parameters:

encodedValue - Textual (possibly formatted) number representation to write

Throws:

IOException - if there is either an underlying I/O problem or encoding issue at format layer

writeNumber

public void writeNumber(char[] encodedValueBuffer,
 int offset,
 int length)
                 throws IOException

Description copied from class: JsonGenerator

Overrides:

writeNumber in class JsonGenerator

Parameters:

encodedValueBuffer - Buffer that contains the textual number representation to write

offset - Offset of the first character of value to write

length - Length of the value (in characters) to write

Throws:

IOException - if there is either an underlying I/O problem or encoding issue at format layer

public void writeBoolean(boolean state)
                  throws IOException

Description copied from class: JsonGenerator

Method for outputting literal JSON boolean value (one of Strings 'true' and 'false'). Can be called in any context where a value is expected (Array value, Object field value, root-level value). Additional white space may be added around the value if pretty-printing is enabled.

Specified by:

_verifyValueWrite in class GeneratorBase

Parameters:

typeMsg - Additional message used for generating exception message if value output is NOT legal in current generator output state.

Throws:

IOException - if there is either an underlying I/O problem or encoding issue at format layer

flush

public void flush()
           throws IOException

Description copied from class: JsonGenerator

Method called to flush any buffered content to the underlying target (output stream, writer), and to flush the target itself as well.

Specified by:

flush in interface Flushable

Specified by:

flush in class GeneratorBase

close

public void close()
           throws IOException

Description copied from class: JsonGenerator

Method called to close this generator, so that no more content can be written.

Whether the underlying target (stream, writer) gets closed depends on whether this generator either manages the target (i.e. is the only one with access to the target -- case if caller passes a reference to the resource such as File, but not stream); or has feature JsonGenerator.Feature.AUTO_CLOSE_TARGET enabled. If either of above is true, the target is also closed. Otherwise (not managing, feature not enabled), target is not closed.

Specified by:

close in class GeneratorBase

Throws:

IOException - if there is either an underlying I/O problem

                                 throws IOException

Method called when String to write is long enough not to fit completely in temporary copy buffer. If so, we will actually copy it in small enough chunks so it can be directly fed to single-segment writes (instead of maximum slices that would fit in copy buffer)

Throws:
