CFArrayApplierFunction

Prototype of a callback function that may be applied to every value in an array.

Declaration

typealias CFArrayApplierFunction = (UnsafeRawPointer?, UnsafeMutableRawPointer?) -> Void

Parameters

  • value:

    The current value in an array.

  • context:

    The program-defined context parameter given to the applier function.

Discussion

This callback is passed to the CFArrayApplyFunction(_:_:_:_:) function, which iterates over the values in an array and applies the behavior defined in the applier function to each value in an array.
