wait

private int wait(ByteBuffer buffer,

Throws:

IOException

rewind

available

public int available()

Overrides:

available in class InputStream

read

public int read(long timeout,
 boolean isPeek)
         throws IOException

Specified by:

read in class NonBlockingInputStream

Throws:

IOException

readBuffered

public int readBuffered(byte[] b,
 int off,

                 throws IOException

Overrides:

readBuffered in class NonBlockingInputStream

Throws:

IOException

setIoException

public void setIoException(IOException exception)

checkIoException

protected void checkIoException()
                         throws IOException

Throws:

IOException

write

void write(byte[] cbuf,
 int off,
 int len)
    throws IOException

Throws:

IOException

flush

void flush()

closeWriter

public void closeWriter()

Signals that the write side has been closed and no more data will be written. Any buffered data can still be read; reads will return NonBlockingInputStream.EOF only after all buffered data has been consumed. This is analogous to closing the write end of a Unix pipe: the read end drains remaining data before seeing EOF.

close

public void close()
           throws IOException

Description copied from class: NonBlockingInputStream

Closes this input stream and marks it as closed.

Subsequent read operations behavior depends on the PROP_CLOSE_MODE setting:

• "strict" - Throw ClosedException
• "warn" - Log a warning but continue (default in JLine 3.x)
• "lenient" - Silently allow access

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Overrides:

close in class NonBlockingInputStream

Throws:

IOException - if an I/O error occurs
