Method Detail

deserialize

public T deserialize(JsonReader reader,
                     JsonDeserializationContext ctx)
              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
