Method Detail

computeHashCode

public void computeHashCode()

Description copied from class: StateHashTuple

This method computes the hashCode for this object and saves it to the hashCode field beloning to the abstract class.

Specified by:

computeHashCode in class StateHashTuple

intArrayCode

protected int intArrayCode(int[] array)

Returns an int value for an int array

Parameters:

array - the int array

Returns:

an int value for it

getDiscrteizedValue

protected int getDiscrteizedValue(Attribute att,
                      double val)

equals

public boolean equals(java.lang.Object other)

Overrides:

equals in class StateHashTuple

objectsMatch

protected boolean objectsMatch(ObjectInstance o,
                   ObjectInstance oo)

Compares the values for each attribute of the objects, assuming they are the same class. To return true, all discrete values much be the same and all continuous values must discretize to the same value.

Parameters:

o - one object to compare

oo - another object to compare that is assumed to be the same class

Returns:

whether o and oo are equivelent after discretization of their continuous attribute values.
