transform

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

Description copied from interface: Transformer

Transforms an input data to some custom representation.

Specified by:

transform in interface Transformer<Object,Buffer>

Overrides:

transform in class SequenceEncoder<Object>

Parameters:

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

Returns:

the result TransformationResult

Throws:

TransformationException

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<Object,Buffer>

Overrides:

release in class AbstractTransformer<Object,Buffer>

Parameters:

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

get

protected Object get(AttributeStorage storage,
                     Object sequence)

Description copied from class: SequenceEncoder

Gets a current sequence element.

Specified by:

get in class SequenceEncoder<Object>

Parameters:

storage - attribute storage.

sequence - sequence object.

Returns:

component sequence element.

previous

protected boolean previous(AttributeStorage storage,
                           Object sequence)

Description copied from class: SequenceEncoder

Moves to previous sequence element and makes it current. Returns true, if there is previous elements in sequence, or false otherwise.

Specified by:

previous in class SequenceEncoder<Object>

Parameters:

storage - attribute storage.

sequence - sequence object.

Returns:

true, if there is previous elements in sequence, or false otherwise.

next

protected boolean next(AttributeStorage storage,
                       Object sequence)

Description copied from class: SequenceEncoder

Moves to next sequence element and makes it current. Returns true, if there is next elements in sequence, or false otherwise.

Specified by:

next in class SequenceEncoder<Object>

Parameters:

storage - attribute storage.

sequence - sequence object.

Returns:

true, if there is next elements in sequence, or false otherwise.

size

protected int size(AttributeStorage storage,
                   Object sequence)

Description copied from class: SequenceEncoder

Returns the size of the sequence.

Specified by:

size in class SequenceEncoder<Object>

Parameters:

storage - attribute storage.

sequence - sequence object.

Returns:

the size of the sequence.

saveState

protected void saveState(AttributeStorage storage,
                         int currentElementIdx,
                         TransformationResult<Buffer> lastResult)
