Specified by:

transformImpl in class AbstractTransformer<Buffer,java.lang.String>

Throws:

TransformationException

parseWithLengthPrefix

protected TransformationResult<Buffer,java.lang.String> parseWithLengthPrefix(AttributeStorage storage,
                                                                                    Buffer input)
