Class ExtraClassification

java.lang.Object
  com.sun.labs.minion.classification.ExtraClassification

All Implemented Interfaces:

com.sun.labs.util.props.Component, com.sun.labs.util.props.Configurable

public class ExtraClassification
extends java.lang.Object
implements com.sun.labs.util.props.Configurable

A configurable container that can be used to describe a set of classification operations to perform that would not be done by the standard classification approach. In particular, this class can be used to apply classifiers that were built from the contents of one vectored field against the contents of a different vectored field.

Normally, classifiers are only applied against the vectored fields from which they were built, but there may be cases where this behavior needs to be overridden. By providing a list of instances of this class to the ClassifierManager.PROP_EXTRA_CLASSIFICATIONS property. A set of non-standard classification operations can be performed.
