Detailed Description

CPCompoundPredicate is a subclass of CPPredicate used to represent logical “gate” operations (AND/OR/NOT) and comparison operations.

Comparison operations are based on two expressions, as represented by instances of the CPExpression class. Expressions are created for constant values, key paths, and so on.

A compound predicate with 0 elements evaluates to TRUE, and a compound predicate with a single sub-predicate evaluates to the truth of its sole subpredicate.

◆ andPredicateWithSubpredicates:()

+ (CPPredicate) andPredicateWithSubpredicates: (CPArray)  subpredicates
implementation

Returns a new predicate formed by AND-ing the predicates in a given array.

Parameters
subpredicatesAn array of CPPredicate objects.
Returns
A new predicate formed by AND-ing the predicates specified by subpredicates.

Definition at line 76 of file CPCompoundPredicate.j.
