All Implemented Interfaces:

Term

public class AndNode
extends OperationNode

This is the class for And node of the IF-statement. Its functionality is very much determined by OperationNode and AndInterpreter, which are configured to deliver the following semantics:

This operation expects one or more Terms, each returning a Types.BOOLEAN_TYPE type, and returns a value of type Types.BOOLEAN_TYPE. The evaluation result is "true", if and only if all Terms of the AndNode evaluate to boolean "true".
