              throws JsonDeserializationException

Deserializes a JSON input into an object.

Parameters:

reader - JsonReader used to read the JSON input

ctx - Context for the full deserialization process

Returns:

the deserialized object

Throws:

JsonDeserializationException - if an error occurs during the deserialization

deserialize

public T deserialize(JsonReader reader,
JsonDeserializationContext ctx,
JsonDeserializerParameters params)
              throws JsonDeserializationException

Deserializes a JSON input into an object.

Parameters:

reader - JsonReader used to read the JSON input

ctx - Context for the full deserialization process

params - Parameters for this deserialization

Returns:

the deserialized object

Throws:

JsonDeserializationException - if an error occurs during the deserialization

deserializeNullValue

protected T deserializeNullValue(JsonReader reader,
JsonDeserializationContext ctx,
JsonDeserializerParameters params)

Deserialize the null value. This method allows children to override the default behaviour.

Parameters:

reader - JsonReader used to read the JSON input

ctx - Context for the full deserialization process

params - Parameters for this deserialization

Returns:

the deserialized object

doDeserialize

protected abstract T doDeserialize(JsonReader reader,
JsonDeserializationContext ctx,
JsonDeserializerParameters params)

Deserializes a non-null JSON input into an object.

Parameters:

reader - JsonReader used to read the JSON input

ctx - Context for the full deserialization process

params - Parameters for this deserialization

Returns:

the deserialized object

setBackReference

public void setBackReference(java.lang.String referenceName,
java.lang.Object reference,
T value,
JsonDeserializationContext ctx)

Set the back reference.

Parameters:

referenceName - name of the reference

reference - reference to set

value - value to set the reference to.

ctx - Context for the full deserialization process
