Detailed Description

A class for binary comparison operators.

The Common Catalog Query Language defines a standard set of comparison operators (=, <, >, >=, <=, <>). These comparison operators are encoded using the complex type BinaryComparisonOp. This type definition includes the matchCase attribute which is Boolean type and controls whether string comparisons are case sensitive or not. A true value means that string comparisons are case sensitive. This is the default value. A false value means that string comparisons are case insensitive.
The following operators are defined in the Filter Encoding specification:

PropertyIsEqualTo
PropertyIsPropertyIsNotEqualTo
PropertyIsPropertyIsLessThan
PropertyIsPropertyIsGreaterThan
PropertyIsPropertyIsLessThanOrEqualTo
PropertyIsPropertyIsGreaterThanOrEqualTo
