NSComparisonPredicate

A specialized predicate for comparing expressions.

Declaration

class NSComparisonPredicate

Overview

Use comparison predicates to compare the results of two expressions. You create a comparison predicate with an operator, a left expression, and a right expression, and use instances of the NSExpression class to represent those expressions. When you evaluate the predicate, it returns a BOOL value as the result of invoking the operator with the results of evaluating the expressions.
