VuoList_VuoLeapPointable_release()

void VuoList_VuoLeapPointable_release

(

VuoList_VuoLeapPointable

This function is provided for use in polymorphism; it just calls VuoRelease().

VuoList_VuoLeapPointable_retain()

void VuoList_VuoLeapPointable_retain

(

VuoList_VuoLeapPointable

list

)

Retains the list.

This function is provided for use in polymorphism; it just calls VuoRetain().

VuoListAppendValue_VuoLeapPointable()

void VuoListAppendValue_VuoLeapPointable	(	VuoList_VuoLeapPointable	list,
		const VuoLeapPointable	value
	)

Appends value to list.

VuoListCopy_VuoLeapPointable()

VuoList_VuoLeapPointable VuoListCopy_VuoLeapPointable

(

const VuoList_VuoLeapPointable

list

)

Makes a shallow copy of list — its items are retained (not copied) by the new list.

VuoListCreate_VuoLeapPointable()

VuoList_VuoLeapPointable VuoListCreate_VuoLeapPointable

(

void

)

Creates a new list of VuoLeapPointable items.

VuoListCreateWithCount_VuoLeapPointable()

VuoList_VuoLeapPointable VuoListCreateWithCount_VuoLeapPointable	(	const unsigned long	count,
		const VuoLeapPointable	value
	)

Creates a new list of count instances of value.

Use this in conjunction with VuoListGetData_VuoLeapPointable to quickly initialize a large list.

VuoListCreateWithValueArray_VuoLeapPointable()

VuoList_VuoLeapPointable VuoListCreateWithValueArray_VuoLeapPointable	(	const VuoLeapPointable *	values,
		const unsigned long	valueCount
	)

Creates a new list containing the items in the C array values.

The list retains each item in values. The caller may discard values after this function returns.

VuoListExchangeValues_VuoLeapPointable()

void VuoListExchangeValues_VuoLeapPointable	(	VuoList_VuoLeapPointable	list,
		const unsigned long	indexA,
		const unsigned long	indexB
	)

Swaps the value at indexA with the value at indexB.

VuoListForeach_VuoLeapPointable()

void VuoListForeach_VuoLeapPointable	(	const VuoList_VuoLeapPointable	list,
		bool(^)(const VuoLeapPointable value)	function
	)

Applies function to each item in list, serially in order of index.

If function returns false, visiting will stop immediately (possibly before all items have been visited).

Changed in Vuo 2.0.0:

New.

VuoListGetCount_VuoLeapPointable()

unsigned long VuoListGetCount_VuoLeapPointable

(

const VuoList_VuoLeapPointable

list

)

Returns the number of items in list.

VuoListGetData_VuoLeapPointable()

VuoLeapPointable * VuoListGetData_VuoLeapPointable

(

const VuoList_VuoLeapPointable

list

)

Returns a pointer to a C array containing the list items.

Use this if you need a fast way to get or change multiple list items.

You can modify values in the list by changing them in this array. Just don't attempt to access beyond the list size.

The pointer becomes invalid if you modify the list size using other functions (e.g., Insert, Prepend, Append, Cut, Remove); if you use those functions, just get a new pointer by calling this function again.

If the list has no items, returns NULL.

The pointer remains owned by the list; don't free it.

VuoListGetValue_VuoLeapPointable()

VuoLeapPointable VuoListGetValue_VuoLeapPointable	(	const VuoList_VuoLeapPointable	list,
		const unsigned long	index
	)

Returns the item at index.

Index values start at 1.

If the list has no items, returns a default value (an empty/zero value of VuoLeapPointable).

Attempting to access an out-of-bounds index returns the first item in the list (if the index is 0), or last item in the list (if the index is greater than the list size).

If iterating over an entire list, consider using VuoListGetData_VuoLeapPointable or VuoListForeach_VuoLeapPointable.

VuoListInsertValue_VuoLeapPointable()

void VuoListInsertValue_VuoLeapPointable	(	const VuoList_VuoLeapPointable	list,
		const VuoLeapPointable	value,
		const unsigned long	index
	)

Inserts value immediately before index.

Index values start at 1.

Inserting at index 0 prepends the value to the list. Inserting at an index beyond the last value in the list appends the value to the list.

VuoListPrependValue_VuoLeapPointable()

void VuoListPrependValue_VuoLeapPointable	(	VuoList_VuoLeapPointable	list,
		const VuoLeapPointable	value
	)

Prepends value to list.

VuoListRemoveAll_VuoLeapPointable()

void VuoListRemoveAll_VuoLeapPointable

(

VuoList_VuoLeapPointable

list

)

Removes all items from list.

VuoListRemoveFirstValue_VuoLeapPointable()

void VuoListRemoveFirstValue_VuoLeapPointable

(

VuoList_VuoLeapPointable

list

)

Removes the first item from list.

VuoListRemoveLastValue_VuoLeapPointable()

void VuoListRemoveLastValue_VuoLeapPointable

(

VuoList_VuoLeapPointable

list

)

Removes the last item from list.

VuoListRemoveValue_VuoLeapPointable()

void VuoListRemoveValue_VuoLeapPointable	(	VuoList_VuoLeapPointable	list,
		const unsigned long	index
	)

Removes the item at index.

Index values start at 1.

Attempting to remove index 0 or an index beyond the last value in the list has no effect.

VuoListReverse_VuoLeapPointable()

void VuoListReverse_VuoLeapPointable

(

VuoList_VuoLeapPointable

list

)

Reverses the order of the items in list.

VuoListSetValue_VuoLeapPointable()

void VuoListSetValue_VuoLeapPointable	(	const VuoList_VuoLeapPointable	list,
		const VuoLeapPointable	value,
		const unsigned long	index,
		bool	expandListIfNeeded
	)

Changes the item at index.

Index values start at 1.

If expandListIfNeeded is false — If the list has no items, nothing is changed. Attempting to change an out-of-bounds index changes the first item in the list (if the index is 0), or last item in the list (if the index is greater than the list size).

If expandListIfNeeded is true — If the list has less than index items, it is expanded to accommodate the specified index. If index is 0, the list is resized to contain 1 item set to value.

VuoListShuffle_VuoLeapPointable()

void VuoListShuffle_VuoLeapPointable	(	VuoList_VuoLeapPointable	list,
		const double	chaos
	)

Generates a random permutation of list.

chaos ranges from 0 to 1. When chaos is 1, a full Fisher–Yates shuffle is performed. When less than 1, fewer iterations are performed.

VuoListSubset_VuoLeapPointable()

VuoList_VuoLeapPointable VuoListSubset_VuoLeapPointable	(	VuoList_VuoLeapPointable	list,
		const signed long	startIndex,
		const unsigned long	itemCount
	)

Returns a new list containing items from the original list in the range specified by startIndex and itemCount.

Items in the new list are retained (not copied) from the original list.
