  edu.indiana.iucbrf.problem.Problem

public class Problem
extends java.lang.Object
implements java.io.Serializable, Featured, java.lang.Comparable, XMLRepresentable

Classes in the Problem component package are used both as a part of a Case object and as stand-alone descriptors of new problems entering the system. A problem is represented as a FeatureCollection of Feature objects. Each Feature type may be as complex as needed, so this is not a restriction of expressive power. All Problem objects of a particular domain-specific implementation of this class must contain the same number and type of features.
Note: Any extension must implement Serializable, if case base file save and load functionality is desired.

A collection of the features.

Constructor Detail

Problem

protected Problem()

Problem

public Problem(FeatureCollection supplied_features)

Creates a populated problem defaults to NOT being FeatureSpecd

Method Detail

toString

public java.lang.String toString()

Create a string representation of this problem.

Overrides:

toString in class java.lang.Object

toString

public java.lang.String toString(Domain domain)

Specified by:

toString in interface Featured

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

toSwing

public javax.swing.JComponent toSwing(Domain domain)

Specified by:

toSwing in interface SwingRepresentableWithDomain

toXML

public java.lang.String toXML(Domain domain)

Specified by:

toXML in interface XMLRepresentable

fromXML

public void fromXML(java.lang.String XMLString)

Specified by:

fromXML in interface XMLRepresentable

constructIndices

public ProblemIndices constructIndices(Domain domain)

Constructs a ProblemIndices.

getFeature

public Feature getFeature(FeatureKey key)

Get the value of a particular feature.

Specified by:

getFeature in interface Featured

Parameters:

featureID - The index of the desired feature.

Returns:

An Object that is the desired feature value.

compareTo

public int compareTo(java.lang.Object obj)

Specified by:

compareTo in interface java.lang.Comparable

equals

public boolean equals(java.lang.Object other)

Determine if this problem is equal to another. Two problems are equal if each individual feature is equal.

Overrides:

equals in class java.lang.Object

getFeatures

public FeatureCollection getFeatures()

Specified by:

getFeatures in interface Featured

update

public void update(Question question,
                   Feature answer,
                   CCBRDomain domain)

getUnestimatedCopy

public Problem getUnestimatedCopy(Domain domain)

Obtain a copy of this problem, not including any estimated features. A new FeatureCollection is constructed, but the features (corresponding only to definitely known features of fullProblem) are references to the same features as those in fullProblem.
