Method Detail

get

protected abstract Object get(AttributeStorage storage,
                              E sequence)

Gets a current sequence element.

Parameters:

storage - attribute storage.

sequence - sequence object.

Returns:

component sequence element.

next

protected abstract boolean next(AttributeStorage storage,
                                E sequence)

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

Parameters:

storage - attribute storage.

sequence - sequence object.

Returns:

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

previous

protected abstract boolean previous(AttributeStorage storage,
                                    E sequence)

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

Parameters:

storage - attribute storage.

sequence - sequence object.

Returns:

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

size

protected abstract int size(AttributeStorage storage,
                            E sequence)

Returns the size of the sequence.

Parameters:

storage - attribute storage.

sequence - sequence object.

Returns:

the size of the sequence.

initialize

public void initialize(SmartTransformer parentTransformer,
                       Field field)

Specified by:

initialize in interface SmartMemberTransformer<E,Buffer>

Overrides:

initialize in class AbstractSmartMemberEncoder<E>

transform

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

Description copied from interface: Transformer
