Class EqualsTest

java.lang.Object
  wt.rule.algorithm.EqualsTest

All Implemented Interfaces:

RuleAlgorithm

public final class EqualsTest
extends Object
implements RuleAlgorithm

two objects, determine the equality. Object to Object comparison. The difference here is we would like to have the EqualsTest that doesn't force construction of transient String objects when comparing its arguments. If the length of the arguments passed is not two, throw exception If two arguments passed are of different type, throw exception Call args[0].equals(args[1]) to do the object to object comparision, return the result. If the specific object's equals() method is not implemented explicitly, equals() from its parents will be used.

Supported API: true

Extendable: false
