procedure	A procedure to apply every item.

FOUNDATION_EXTERN void NSAApplyWithIndex	(	id< NSFastEnumeration >	enumerator,
		NSAObjectProcedureWithIndex	procedure
	)

Applies mapper with index to every item of enumerator.

Parameters

enumerator	Input object source enumerator.
procedure	A procedure to apply every item.

FOUNDATION_EXTERN NSEnumerator* NSAFilter	(	NSEnumerator *	enumerator,
		NSAObjectPicker	filter
	)

Applies filter to every item of given enumerator and returns an enumerator with the filter result is YES.

Parameters

enumerator	Input object source enumerator.
filter	Object filter to decide inclues or not.

Returns: An enumerator with filter result of items of given enumerater is YES.

FOUNDATION_EXTERN NSEnumerator* NSAFilterWithIndex	(	NSEnumerator *	enumerator,
		NSAObjectPickerWithIndex	filter
	)

Applies filter with index to every item of given enumerator and returns an enumerator with the filter result is YES.

Parameters

enumerator	Input object source enumerator.
filter	Object filter to decide inclues or not.

Returns: An enumerator with filter result of items of given enumerater is YES.

FOUNDATION_EXTERN NSEnumerator* NSAMap	(	id< NSFastEnumeration >	enumerator,
		NSAObjectUnaryOperator	mapper
	)

Applies mapper to every item of enumerator and returns an enumerator with every result items.

Parameters

enumerator	Input object source enumerator.
mapper	Object mapper to apply every item.

Returns: An enumerator with every mapper applied result.

FOUNDATION_EXTERN NSEnumerator* NSAMapFilter	(	NSEnumerator *	enumerator,
		NSAObjectUnaryOperator	mapper
	)

Applies mapper to every item of enumerator and returns an enumerator with every result items except nil.

Parameters

enumerator	Input object source enumerator.
mapper	Object mapper to apply every item. Return nil to pass.

Returns: Take each object from given enumerator and returns an enumerator with mapped value by mapper. If the result is nil, it will not be enumerated.

See also: NSAMap; NSAFilter

FOUNDATION_EXTERN NSEnumerator* NSAMapFilterWithIndex	(	NSEnumerator *	enumerator,
		NSAObjectUnaryOperatorWithIndex	mapper
	)

Applies mapper with index to every item of enumerator and returns an enumerator with every result items except nil.

Parameters

enumerator	Input object source enumerator.
mapper	Object mapper to apply every item. Return nil to pass.

Returns: Take each object from given enumerator and returns an enumerator with mapped value by mapper. If the result is nil, it will not be enumerated.

See also: NSAMap; NSAFilter

FOUNDATION_EXTERN NSEnumerator* NSAMapWithIndex	(	id< NSFastEnumeration >	enumerator,
		NSAObjectUnaryOperatorWithIndex	mapper
	)

Applies mapper with index to every item of enumerator and returns an enumerator with every result items.

Parameters

enumerator	Input object source enumerator.
mapper	Object mapper to apply every item.

Returns: An enumerator with every mapper applied result.

FOUNDATION_EXTERN id NSAReduce	(	NSEnumerator *	enumerator,
		NSAObjectBinaryOperator	operation
	)

Applies operation of two arguments cumulatively to the items of enumerator, from left to right, so as to reduce the iterable to a single value. Uses first and second value as seed.

Given enumerator must enumerate more than a object.

Parameters

enumerator	Input object source enumerator.
operation	An operator to apply every item and latest result. If it is first object, operation is not used and keep the object as latest result.

Returns: An object.

See also: NSAReduceWithInitialObject

FOUNDATION_EXTERN id NSAReduceWithInitialObject	(	id< NSFastEnumeration >	enumerator,
		NSAObjectBinaryOperator	operation,
		id	initialObject

Given enumerator must enumerate more than a object.

Parameters

enumerator	Input object source enumerator.
operation	An operator to apply every item and latest result. If it is first object, uses initialObject as latest result.
initialObject	The initial value to reduce with first element of enumerator.

Returns: An object.
