Method Detail

createDeserializer

public XMLDeserializer createDeserializer()

Description copied from interface: BaseContext

Returns an instance of the XMLDeserializer that can be used to deserialize project resources. Note that this is the only safe way to obtain an instance of XMLDeserializer, because the context will pass the new deserializer around to all loaded modules, giving them a chance to initialize any custom deserialization deletes on it first.
