Method Detail

transform

public TransformationResult<String> transform(AttributeStorage storage,
                                              Buffer input,
                                              String output)
                                       throws TransformationException

Description copied from interface: Transformer

Transforms an input data to some custom representation.

Parameters:

storage - the external state storage, where Transformer could retrieve or store its state.

Returns:

the result TransformationResult

Throws:

TransformationException

parseWithLengthPrefix

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

parseWithTerminatingSeq

protected TransformationResult<String> parseWithTerminatingSeq(AttributeStorage storage,
                                                               Buffer input)

release

public void release(AttributeStorage storage)

Description copied from interface: Transformer

The Transformer has done its work and can release all associated resource.

Specified by:

release in interface Transformer<Buffer,String>

Overrides:

release in class AbstractTransformer<Buffer,String>

Parameters:

storage - the external state storage, where Transformer could retrieve or store its state.

getCharset

public Charset getCharset()

setCharset

public void setCharset(Charset charset)

saveState

protected void saveState(AttributeStorage storage,
                         TransformationResult<String> result,
                         Integer state)
