wt.rule.algorithm.CaseBranch

All Implemented Interfaces:

RuleAlgorithm

public final class CaseBranch
extends Object
implements RuleAlgorithm

This is a branch algorithm, which is similar to BooleanBranch, but allows any odd number of parts as input and allows a default return. What if the length passed in is not an odd number, throw exception immediately, since there isn't a default return for the "case".If the odd number parameters passed is not a Boolean, throw exception.The exception message contains which case failed to indicate the problem when happened.

Supported API: true

Extendable: false
