Field Detail

LABEL_INDICES_ID

public static final OptionID LABEL_INDICES_ID

A comma separated list of the indices of labels (may be numeric), counting whitespace separated entries in a line starting with 0. The corresponding entries will be treated as a label.

VECTOR_TYPE_ID

public static final OptionID VECTOR_TYPE_ID

Parameter to specify the type of vectors to produce.

labelIndices

protected long[] labelIndices

Keeps the indices of the attributes to be treated as a string label.

factory

protected NumberVector.Factory<V extends NumberVector> factory

Factory object.

Method Detail

configure

public void configure(Parameterization config)

Description copied from interface: Parameterizer

Configure the class.

Note: the status is collected by the parameterization object, so that multiple errors may arise and be reported in one run.

Specified by:

configure in interface Parameterizer

Overrides:

configure in class AbstractStreamingParser.Par

Parameters:

config - Parameterization

getFactory

protected void getFactory(Parameterization config)

Get the object factory.

Parameters:

config - Parameterization

getLabelIndices

protected void getLabelIndices(Parameterization config)

Get the label indices.

Parameters:

config - Parameterization

make

public NumberVectorLabelParser<V> make()

Description copied from interface: Parameterizer

Make an instance after successful configuration.

Note: your class should return the exact type, only this very broad interface should use Object as return type.

Specified by:

make in interface Parameterizer

Specified by:

make in class AbstractStreamingParser.Par

Returns:

a new instance
