withArray

Creates and initializes an OSSet populated with the contents of an OSArray.

Declaration

static OSSet * withArray( 
 const OSArray *array, 
 unsigned int capacity = 0);

Parameters

  • array:

    An array whose objects will be stored in the new OSSet.

  • capacity:

    The initial storage capacity of the new set object. If 0, the capacity is set to the number of objects in array; otherwise capacity must be greater than or equal to the number of objects in array.

Return Value

An instance of OSSet containing the objects of array, with a retain count of 1; NULL on failure.

Overview

Each distinct object in array is added to the new set.

array must be non-NULL. If capacity is nonzero, it must be greater than or equal to count. The new OSSet will grow as needed to accommodate more key-object pairs (unlikeCFMutableSet, for which the initial capacity is a hard limit).

The objects in array are retained for storage in the new set, not copied.
