All Implemented Interfaces:

Term

public class NotNode
extends OperationNode

This is the class for Not node of the IF-statement. Its functionality is very much determined by OperationNode and NotInterpreter, which are configured to deliver the following semantics:

This operation expects one and only one Term of type Types.BOOLEAN_TYPE, and returns a value of type Types.BOOLEAN_TYPE. The evaluation result is "true", if and only if evaluation of the Term passed to the evaluate method results in a boolean "false".

NotNode

public NotNode(XMLPolicyParser p,
               org.xml.sax.Attributes attrs)

This constructor builds a NotNode given the XMLPolicyParser and the set of attributes of this XML element. It expects that there is one and only one child node.

Parameters:

p - - the XMLPolicyParser that builds this NotNode

attrs - - the attributes of this XML element
