Method Detail

transform

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

Description copied from interface: Transformer

Transforms an input data to some custom representation.

Specified by:

transform in interface Transformer<Buffer,Object>

Overrides:

transform in class SequenceDecoder<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<Buffer,Object>

Overrides:

release in class SequenceDecoder<Object>

Parameters:

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

createSequence

protected Object createSequence(AttributeStorage storage,
                                int size)

Description copied from class: SequenceDecoder

Creates a sequence object with certain size.

Specified by:

createSequence in class SequenceDecoder<Object>

Parameters:

storage - attribute storage

size - the sequence size

set

protected void set(AttributeStorage storage,

next

protected boolean next(AttributeStorage storage,
                       Object sequence)

Description copied from class: SequenceDecoder

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 SequenceDecoder<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: SequenceDecoder

Returns the size of the sequence.

Specified by:

size in class SequenceDecoder<Object>

Parameters:

storage - attribute storage.

sequence - sequence object.

Returns:

the size of the sequence.
