All Implemented Interfaces:

CDataComparator

public class CDataAndComparator

extends java.lang.Object

implements CDataComparator

Implementation of CDataComparator that enables AND logic to be applied to character data comparisons. Delegates to two contained CDataComparators and implements the interface by returning true only if both child comparators match the source character array. Works with a ProgrammableSAXFilter as a component of an ElementComparator.

XML Configuration Template:

Description copied from interface: CDataComparator

determines if the character data source matches the criteria of this comparator.

Specified by:

matches in interface CDataComparator

Parameters:

source - character array obtained from original SAX parser.

start - position of the first character in the array to consider.

length - number of characters to consider.

Returns:

true if the characters match the criteria defined by this comparator. false otherwise.

initialize
