Method Details

map

public <T> T map(Object source,
 Class<T> targetType,
 Configuration configuration)

Maps supplied JSON source Object to a given target class or collection. This implementation ignores the JsonPath's Configuration argument.

Specified by:

map in interface MappingProvider

Type Parameters:

T - the mapped result type

Parameters:

source - object to map

targetType - the type the source object should be mapped to

configuration - current configuration

Returns:

return the mapped object

map

public <T> T map(Object source,
 TypeRef<T> targetType,
 Configuration configuration)

Maps supplied JSON source Object to a given target type or collection. This implementation ignores the JsonPath's Configuration argument.

Method may produce a ClassCastException on an attempt to cast the result of JSON mapping operation to a requested target type, especially if a parameterized generic type is used.

Specified by:

map in interface MappingProvider

Type Parameters:

T - the mapped result type

Parameters:

source - object to map

targetType - the type the source object should be mapped to

configuration - current configuration

Returns:

return the mapped object

mapImpl

private Object mapImpl(Object source,
 Type targetType)

mapIntegralJsonNumber

private <T> T mapIntegralJsonNumber(jakarta.json.JsonNumber jsonNumber,
 Class<?> targetType)

mapDecimalJsonNumber

private <T> T mapDecimalJsonNumber(jakarta.json.JsonNumber jsonNumber,
 Class<?> targetType)

unwrapJsonValue

private Object unwrapJsonValue(Object jsonValue)

newCollectionOfType

private Collection<Object> newCollectionOfType(Class<?> collectionType)
                                        throws MappingException

Creates new instance of Collection type specified by the argument. If the argument refers to an interface, then a matching Java standard implementation is returned; if it is a concrete class, then method attempts to instantiate an object of that class given there is a public no-arg constructor available.

Parameters:

collectionType - collection type; may be an interface or a class

Returns:

instance of collection type identified by the argument

Throws:

MappingException - on a type that cannot be safely instantiated

newNoArgInstance

private Object newNoArgInstance(Class<?> targetType)
                         throws MappingException

Lists all publicly accessible constructors for the Class identified by the argument, including any constructors inherited from superclasses, and uses a no-args constructor, if available, to create a new instance of the class. If argument is interface, this method returns null.

Parameters:

targetType - class type to create instance of

Returns:

an instance of the class represented by the argument

Throws:

MappingException - if no-arg public constructor is not there

findMethod

private Method findMethod(Class<?> clazz,
 String name,
 Class<?>... paramTypes)

Locates optional API method on the supplied JSON-B API implementation class with the supplied name and parameter types. Searches the superclasses up to Object, but ignores interfaces and default interface methods. Returns null if no Method can be found.

Parameters:

clazz - the implementation class to reflect upon

name - the name of the method

paramTypes - the parameter types of the method

Returns:

the Method reference, or null if none found

getRawClass

private Class<?> getRawClass(Type targetType)

getFirstTypeArgument

private Type getFirstTypeArgument(Type targetType)
