create

public <T> TypeAdapter<T> create(Gson gson,
 TypeToken<T> type)

Description copied from interface: TypeAdapterFactory

Returns a type adapter for type, or null if this factory doesn't support type.

Specified by:

create in interface TypeAdapterFactory

createInstance

public Object createInstance(Type type)

Hook for the graph adapter to get a reference to a deserialized value before that value is fully populated. This is useful to deserialize values that directly or indirectly reference themselves: we can hand out an instance before read() returns.

Gson should only ever call this method when we're expecting it to; that is only when we've called back into Gson to deserialize a tree.

Specified by:

createInstance in interface InstanceCreator<Object>

Parameters:

type - the parameterized T represented as a Type.

Returns:

a default object instance of type T.
