All Implemented Interfaces:

Node

public class ConditionalExpression
extends AbstractNode

Represents an expression that has a conditional operator.

With an odd number of expressions {c0, e0, c1, e1, ..., c_n-1, e_n-1, e_n} represents "if (c0) e0 else if (c1) e1 ... else e_n"; with an even number of expressions {c0, e0, c1, e1, ..., c_n-1, e_n-1} represents "if (c0) e0 else if (c1) e1 ... else if (c_n-1) e_n-1".
