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.
