Method Detail

build

public void build(FrameBlock in)

Description copied from interface: Encoder

Build the transform meta data for the given block input. This call modifies and keeps meta data as encoder state.

Parameters:

in - input frame block

getPartialBuildTasks

public List<Callable<Object>> getPartialBuildTasks(FrameBlock in,
                                                   int blockSize)

Specified by:

getPartialBuildTasks in class ColumnEncoder

mergeBuildPartial

public void mergeBuildPartial(List<Future<Object>> futurePartials,
                              int start,
                              int end)

Specified by:

mergeBuildPartial in class ColumnEncoder

apply

public MatrixBlock apply(FrameBlock in,
                         MatrixBlock out,
                         int outputCol)

Description copied from interface: Encoder

Apply the generated metadata to the FrameBlock and saved the result in out.

Parameters:

in - input frame block

out - output matrix block

outputCol - is a offset in the output matrix. column in FrameBlock + outputCol = column in out

Returns:

output matrix block

apply

public MatrixBlock apply(MatrixBlock in,
                         MatrixBlock out,
                         int outputCol)

Specified by:

apply in class ColumnEncoder

apply

public MatrixBlock apply(FrameBlock in,
                         MatrixBlock out,
                         int outputCol,
                         int rowStart,
                         int blk)

Specified by:

apply in class ColumnEncoder

apply

public MatrixBlock apply(MatrixBlock in,
                         MatrixBlock out,
                         int outputCol,
                         int rowStart,
                         int blk)

Specified by:

apply in class ColumnEncoder

mergeAt

public void mergeAt(ColumnEncoder other)

Description copied from class: ColumnEncoder

Merges another encoder, of a compatible type, in after a certain position. Resizes as necessary. ColumnEncoders are compatible with themselves and EncoderComposite is compatible with every other ColumnEncoders. MultiColumnEncoders are compatible with every encoder

Overrides:

mergeAt in class ColumnEncoder

Parameters:

other - the encoder that should be merged in

getMetaData

public FrameBlock getMetaData(FrameBlock meta)

Description copied from interface: Encoder

Construct a frame block out of the transform meta data.

Parameters:

meta - output frame block

Returns:

output frame block?

initMetaData

public void initMetaData(FrameBlock meta)

Description copied from interface: Encoder

Sets up the required meta data for a subsequent call to apply.

Parameters:

meta - frame block
