Class AbstractFeature

java.lang.Object
  edu.indiana.iucbrf.feature.AbstractFeature

All Implemented Interfaces:

Feature, SwingRepresentable, java.io.Serializable, java.lang.Comparable

Direct Known Subclasses:

AbstractFSMFeature, CharacterFeature, DoubleFeature, ExceptionFeature, InetAddressFeature, IntegerFeature, ObjectFeature, StringFeature, TableFeature, TermVectorFeature

public abstract class AbstractFeature
extends java.lang.Object
implements java.io.Serializable, Feature

This class makes assumptions about Features that are general enough to be applicable to most implementations.

Method Detail

equals

public boolean equals(java.lang.Object other)

Overrides:

equals in class java.lang.Object

compareTo

public int compareTo(java.lang.Object otherFeature)

Compare this feature with another, based on their double values. Note that since this assumes the features are DoubleRepresentable, an IllegalArgumentException will be thrown if the features being compared are not actually DoubleRepresentable. Whether this version or an overriding subclass' version is used:
Return value is < 0 (here, -1) if "this" is less than otherFeature.
Return value is > 0 (here, 1) if "this" is greater than otherFeature.
Return value is = 0 (here, 0) if "this" equals otherFeature.

Specified by:

compareTo in interface java.lang.Comparable

checkAndGetDoubleValue

public static double checkAndGetDoubleValue(java.lang.Object feature)

Get the double value according to getValueAsDouble(), and throwing an exception if the feature is not DoubleRepresentable.

midpoint

public abstract Feature midpoint(Feature other_feature)

Specified by:

midpoint in interface Feature

adjust

public void adjust(double adjustAmount)
            throws CouldNotAdjustException,
                   java.lang.UnsupportedOperationException

Specified by:

adjust in interface Feature

Throws:

CouldNotAdjustException

java.lang.UnsupportedOperationException

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

toSwing

public javax.swing.JComponent toSwing(int detailLevel)

Description copied from interface: SwingRepresentable

Detail level may be ignored by implementations. If used, the standard is for detailLevel 0 to be least detail, with higher values growing more detailed. 0 is least detail, higher numbers are more

Specified by:

toSwing in interface SwingRepresentable

Specified by:

toString in interface Feature

getValue

public java.lang.Object getValue()

Specified by:

getValue in interface Feature

clone

public abstract java.lang.Object clone()

Specified by:

clone in interface Feature

Overrides:
