Class SubcontextList

java.lang.Object

weka.classifiers.lazy.AM.data.SubcontextList

All Implemented Interfaces:

java.lang.Iterable<Subcontext>

public class SubcontextList
extends java.lang.Object
implements java.lang.Iterable<Subcontext>

This class creates and manages a list of subcontexts from a set of previously classified exemplars and an exemplar to be classified. After creating a list of subcontexts, iterate through the subcontexts using the Iterator returned by iterator().

Constructor Summary

Constructors

Constructor	Description
SubcontextList(Labeler labeler, java.util.List<weka.core.Instance> data, boolean ignoreFullMatches)	This is the easiest to use constructor.

Method Summary

Modifier and Type	Method	Description
boolean	equals(java.lang.Object other)	Returns equals if both lists contain the same data in the same subcontexts.
int	getCardinality()
int	getConsideredExemplarCount()
boolean	getIgnoreFullMatches()
Labeler	getLabeler()
java.util.Iterator<Subcontext>	iterator()
int	size()
java.lang.String	toString()	This method is not particularly speedy, since it sorts the contained subcontexts by label.

Constructor Detail

SubcontextList

public SubcontextList(Labeler labeler,
                      java.util.List<weka.core.Instance> data,
                      boolean ignoreFullMatches)

This is the easiest to use constructor. It creates and stores a list of subcontexts given classified exemplars and an exemplar to be classified.

Parameters:

labeler - Labeler for assigning labels to items in data

data - Training data (exemplars)

ignoreFullMatches - if true, will not add entirely matching contexts

Method Detail

getCardinality

public int getCardinality()

Returns:

the number of attributes used to predict an outcome

getIgnoreFullMatches

public boolean getIgnoreFullMatches()

Returns:

True if instances with exact same attribute values as the test instance are removed from the list.

toString

public java.lang.String toString()

This method is not particularly speedy, since it sorts the contained subcontexts by label. It is meant for test purposes only; do not rely on exact output being the same in the future.

Overrides:

toString in class java.lang.Object

equals

public boolean equals(java.lang.Object other)

Returns equals if both lists contain the same data in the same subcontexts. Does not compare the Labeler object.

Overrides:

equals in class java.lang.Object

iterator

public java.util.Iterator<Subcontext> iterator()

Specified by:

iterator in interface java.lang.Iterable<Subcontext>

Returns:

An iterator which returns each of the contained subcontexts.

size

public int size()

getConsideredExemplarCount

public int getConsideredExemplarCount()

Returns:

The number of exemplars considered accepted into the list, e.g. added and not ignored

getLabeler

public Labeler getLabeler()

Returns:

The labeler object used to assign incoming data to subcontexts.
