Description copied from interface: ObjectDeserializer

fastjson invokes this call-back method during deserialization when it encounters a field of the specified type.

In the implementation of this call-back method, you should consider invoking JSON.parseObject(String, Type, Feature[]) method to create objects for any non-trivial field of the returned object.

Specified by:

deserialze in interface ObjectDeserializer

Parameters:

parser - context DefaultJSONParser being deserialized

clazz - The type of the Object to deserialize to

fieldName - parent object field name

Returns:

a deserialized object of the specified type which is a subclass of T

deserialze

public static <T> T deserialze(DefaultJSONParser parser)
