Instance Attribute Details

- (CFSetCopyDescriptionCallBack) copyDescription

The callback used to create a descriptive string representation of each value in the collection. If NULL, the collection will create a simple description of each value. See CFSetCopyDescriptionCallBack for a description of this callback.

Returns:

  • (CFSetCopyDescriptionCallBack)

    The callback used to create a descriptive string representation of each value in the collection. If NULL, the collection will create a simple description of each value. See CFSetCopyDescriptionCallBack for a description of this callback.

- (CFSetEqualCallBack) equal

The callback used to compare values in the collection for equality for some operations. If NULL, the collection will use pointer equality to compare values in the collection. See CFSetEqualCallBack for a description of this callback.

Returns:

  • (CFSetEqualCallBack)

    The callback used to compare values in the collection for equality for some operations. If NULL, the collection will use pointer equality to compare values in the collection. See CFSetEqualCallBack for a description of this callback.

- (CFSetHashCallBack) hash

The callback used to compute a hash code for values in a collection. If NULL, the collection computes a hash code by converting the pointer value to an integer. See CFSetHashCallBack for a description of this callback.

Returns:

  • (CFSetHashCallBack)

    The callback used to compute a hash code for values in a collection. If NULL, the collection computes a hash code by converting the pointer value to an integer. See CFSetHashCallBack for a description of this callback.

- (CFSetReleaseCallBack) release

The callback used to release values as they are removed from the collection. If NULL, values are not released. See CFSetReleaseCallBack for a description of this callback.

Returns:

  • (CFSetReleaseCallBack)

    The callback used to release values as they are removed from the collection. If NULL, values are not released. See CFSetReleaseCallBack for a description of this callback.

- (CFSetRetainCallBack) retain

The callback used to retain each value as they are added to the collection. If NULL, values are not retained. See CFSetRetainCallBack for a descriptions of this function’s parameters.

Returns:

  • (CFSetRetainCallBack)

    The callback used to retain each value as they are added to the collection. If NULL, values are not retained. See CFSetRetainCallBack for a descriptions of this function’s parameters.

- (CFIndex) version

The version number of this structure. If not one of the defined version numbers for this opaque type, the behavior is undefined. The current version of this structure is 0.

Returns:

  • (CFIndex)

    The version number of this structure. If not one of the defined version numbers for this opaque type, the behavior is undefined. The current version of this structure is 0.
