Field Detail

_arrayType

protected final ArrayType _arrayType
Full generic type of the array being deserialized


_untyped

protected final boolean _untyped
Flag that indicates whether the component type is Object or not. Used for minor optimization when constructing result.


_elementClass

protected final Class<?> _elementClass
Type of contained elements: needed for constructing actual result array


_elementDeserializer

protected JsonDeserializer<Object> _elementDeserializer
Element deserializer


_elementTypeDeserializer

protected final TypeDeserializer _elementTypeDeserializer
If element instances have polymorphic type information, this is the type deserializer that can handle it

Constructor Detail

ObjectArrayDeserializer

public ObjectArrayDeserializer(ArrayType arrayType,
                               JsonDeserializer<Object> elemDeser,
                               TypeDeserializer elemTypeDeser)
Method Detail

withDeserializer

public ObjectArrayDeserializer withDeserializer(TypeDeserializer elemTypeDeser,
                                                JsonDeserializer<?> elemDeser)
Overridable fluent-factory method used to create contextual instances


createContextual

public JsonDeserializer<?> createContextual(DeserializationContext ctxt,
                                            BeanProperty property)
                                     throws JsonMappingException
Description copied from interface: ContextualDeserializer
Method called to see if a different (or differently configured) deserializer is needed to deserialize values of specified property. Note that instance that this method is called on is typically shared one and as a result method should NOT modify this instance but rather construct and return a new instance. This instance should only be returned as-is, in case it is already suitable for use.

Specified by:
createContextual in interface ContextualDeserializer
Parameters:
ctxt - Deserialization context to access configuration, additional deserializers that may be needed by this deserializer
property - Method, field or constructor parameter that represents the property (and is used to assign deserialized value). Should be available; but there may be cases where caller can not provide it and null is passed instead (in which case impls usually pass 'this' deserializer as is)
Returns:
Deserializer to use for deserializing values of specified property; may be this instance or a new instance.
Throws:
JsonMappingException

getContentType

public JavaType getContentType()
Description copied from class: ContainerDeserializerBase
Accessor for declared type of contained value elements; either exact type, or one of its supertypes.

Specified by:
getContentType in class ContainerDeserializerBase<Object[]>

getContentDeserializer

public JsonDeserializer<Object> getContentDeserializer()
Description copied from class: ContainerDeserializerBase
Accesor for deserializer use for deserializing content values.

Specified by:
getContentDeserializer in class ContainerDeserializerBase<Object[]>

deserialize

public Object[] deserialize(com.fasterxml.jackson.core.JsonParser jp,
                            DeserializationContext ctxt)
                     throws IOException,
                            com.fasterxml.jackson.core.JsonProcessingException
Description copied from class: JsonDeserializer
Method that can be called to ask implementation to deserialize JSON content into the value type this serializer handles. Returned instance is to be constructed by method itself.

Pre-condition for this method is that the parser points to the first event that is part of value to deserializer (and which is never JSON 'null' literal, more on this below): for simple types it may be the only value; and for structured types the Object start marker. Post-condition is that the parser will point to the last event that is part of deserialized value (or in case deserialization fails, event that was not recognized or usable, which may be the same event as the one it pointed to upon call).

Note that this method is never called for JSON null literal, and thus deserializers need (and should) not check for it.

Specified by:
deserialize in class JsonDeserializer<Object[]>
Parameters:
jp - Parsed used for reading JSON content
ctxt - Context that can be used to access information about this deserialization activity.
Returns:
Deserializer value
Throws:
IOException
com.fasterxml.jackson.core.JsonProcessingException

deserializeWithType

public Object[] deserializeWithType(com.fasterxml.jackson.core.JsonParser jp,
                                    DeserializationContext ctxt,
                                    TypeDeserializer typeDeserializer)
                             throws IOException,
                                    com.fasterxml.jackson.core.JsonProcessingException
Description copied from class: StdDeserializer
Base implementation that does not assume specific type inclusion mechanism. Sub-classes are expected to override this method if they are to handle type information.

Overrides:
deserializeWithType in class StdDeserializer<Object[]>
typeDeserializer - Deserializer to use for handling type information
Throws:
IOException
com.fasterxml.jackson.core.JsonProcessingException

deserializeFromBase64

protected Byte[] deserializeFromBase64(com.fasterxml.jackson.core.JsonParser jp,
                                       DeserializationContext ctxt)
                                throws IOException,
                                       com.fasterxml.jackson.core.JsonProcessingException
Throws:
IOException
com.fasterxml.jackson.core.JsonProcessingException
