Class Method Details

+ (NSPredicate) andPredicateWithSubpredicates(subpredicates)

Returns a new predicate formed by AND-ing the predicates in a given array. An AND predicate with no subpredicates evaluates to TRUE.

Parameters:

Returns:

  • (NSPredicate)

    A new predicate formed by AND-ing the predicates specified by subpredicates.

+ (NSPredicate) notPredicateWithSubpredicate(predicate)

Returns a new predicate formed by NOT-ing a given predicate.

Parameters:

Returns:

  • (NSPredicate)

    A new predicate formed by NOT-ing the predicate specified by predicate.

+ (NSPredicate) orPredicateWithSubpredicates(subpredicates)

Returns a new predicate formed by OR-ing the predicates in a given array. An OR predicate with no subpredicates evaluates to FALSE.

Parameters:

Returns:

  • (NSPredicate)

    A new predicate formed by OR-ing the predicates specified by subpredicates.

Instance Method Details

- (NSCompoundPredicateType) compoundPredicateType

Returns the predicate type for the receiver.

Returns:

- (Object) initWithType(type, subpredicates:subpredicates)

Returns the receiver initialized to a given type using predicates from a given array.

Parameters:

Returns:

  • (Object)

    The receiver initialized with its type set to type and subpredicates array to subpredicates.

- (Array) subpredicates

Returns the array of the receiver’s subpredicates.

Returns:

  • (Array)

    The array of the receiver’s subpredicates.
