All Implemented Interfaces:

Term

public class SubstringsNode
extends OperationNode

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

This operation expects two and only two Terms of type Types.STRING_TYPE, and returns a value of type Types.BOOLEAN_TYPE. The evaluation result is "true", if and only if the first string Term occurs somewhere in the second string Term.

StringInterpreter provides the default implementation of the Substrings operation.

SubstringsNode

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

This constructor builds a SubstringsNode given the XMLPolicyParser and the set of attributes of this XML element. It expects that there are two and only two child nodes.

Parameters:

p - - the XMLPolicyParser that builds this SubstringsNode

attr - - the attributes of this XML element

Method Detail

register

public static void register()

Call this method to register the SubstringsNode with the XMLPolicyParser. It also registers the StringInterpreter in SUBSTRINGS_MODE.
