Method Detail

initInstanceBuilder

protected InstanceBuilder<T> initInstanceBuilder()

Initialize the InstanceBuilder. Returns null if the class isn't instantiable.

Returns:

a InstanceBuilder object.

initDeserializers

protected SimpleStringMap<BeanPropertyDeserializer<T,?>> initDeserializers()

Initialize the SimpleStringMap containing the property deserializers. Returns an empty map if there are no properties to deserialize.

Returns:

a SimpleStringMap object.

initBackReferenceDeserializers

protected SimpleStringMap<BackReferenceProperty<T,?>> initBackReferenceDeserializers()

Initialize the SimpleStringMap containing the back reference deserializers. Returns an empty map if there are no back reference on the bean.

Returns:

a SimpleStringMap object.

initIgnoredProperties

protected java.util.Set<java.lang.String> initIgnoredProperties()

Initialize the Set containing the ignored property names. Returns an empty set if there are no ignored properties.

Returns:

a Set object.

initRequiredProperties

protected java.util.Set<java.lang.String> initRequiredProperties()

Initialize the Set containing the required property names. Returns an empty set if there are no required properties.

Returns:

a Set object.

initIdentityInfo

protected IdentityDeserializationInfo<T> initIdentityInfo()

Initialize the IdentityDeserializationInfo. Returns null if there is no JsonIdentityInfo annotation on bean.

Returns:

a IdentityDeserializationInfo object.

initTypeInfo

protected TypeDeserializationInfo<T> initTypeInfo()

Initialize the TypeDeserializationInfo. Returns null if there is no JsonTypeInfo annotation on bean.

Returns:

a TypeDeserializationInfo object.

initMapSubtypeClassToDeserializer

protected java.util.Map<java.lang.Class,SubtypeDeserializer> initMapSubtypeClassToDeserializer()

Initialize the Map containing the SubtypeDeserializer. Returns an empty map if the bean has no subtypes.

Returns:

a Map object.

initAnySetterDeserializer

protected AnySetterDeserializer<T,?> initAnySetterDeserializer()

Initialize the AnySetterDeserializer. Returns null if there is no method annoted with JsonAnySetter on bean.

Returns:

a AnySetterDeserializer object.

isDefaultIgnoreUnknown

protected boolean isDefaultIgnoreUnknown()

Whether encountering of unknown properties should result in a failure (by throwing a JsonDeserializationException) or not.

Returns:

a boolean.

getDeserializedType

public abstract java.lang.Class getDeserializedType()

getDeserializedType

Returns:

a Class object.

doDeserialize

public T doDeserialize(JsonReader reader,
                       JsonDeserializationContext ctx,

Deserializes a non-null JSON input into an object.

Specified by:

doDeserialize in class JsonDeserializer<T>

Parameters:

ctx - Context for the full deserialization process

params - Parameters for this deserialization

Returns:

the deserialized object

canDeserialize

protected boolean canDeserialize()

canDeserialize

Returns:

a boolean.

deserializeWrapped

public T deserializeWrapped(JsonReader reader,
                            JsonDeserializationContext ctx,
