getName

public java.lang.String getName()

Description copied from interface: Component

Get the name of this component.

Specified by:

getName in interface Component

getDescription

public java.lang.String getDescription()

Description copied from interface: Component

getInputDimension in class Transformer

getOutputDimension

public int getOutputDimension()

Get the dimensionality of the output vectors.

Specified by:

getOutputDimension in class Transformer

add

public void add(Transformer trans)
         throws TransformationException

Add a component to the transformation

Throws:

TransformationException

transform

public void transform(double[] in,
                      double[] out)

Transform a vector

Specified by:

transform in class Transformer

Parameters:

in - The input vector.

out - The output vector, it may be the same as the input vector if the dimensionalities are the same. All transformers are expected to work with aliased inputs and output.

check

public void check()

See if there are any optimizations we can do.

inverse

public Converter inverse()

Return the inverse of this series of transformations.

Specified by:

inverse in class Transformer

isInverse

public boolean isInverse(Transformer t)

Is this the inverse of another transformation.

Specified by:

isInverse in class Transformer
