char* VuoList_VuoVideoFrame_getSummary | ( | const VuoList_VuoVideoFrame | value | ) |
Produces a brief human-readable summary of value
.
VuoList_VuoVideoFrame VuoList_VuoVideoFrame_makeFromJson | ( | struct json_object * | js | ) |
Decodes the JSON object js
to create a new value.
VuoList_VuoVideoFrame VuoList_VuoVideoFrame_makeFromString | ( | const char * | str | ) |
Automatically generated function.
void VuoListAppendValue_VuoVideoFrame | ( | VuoList_VuoVideoFrame | list, |
const VuoVideoFrame | value | ||
) |
Appends value
to list
.
VuoList_VuoVideoFrame VuoListCopy_VuoVideoFrame | ( | const VuoList_VuoVideoFrame | list | ) |
Makes a shallow copy of list
— its items are retained (not copied) by the new list.
VuoList_VuoVideoFrame VuoListCreate_VuoVideoFrame | ( | void | ) |
Creates a new list of VuoVideoFrame elements.
VuoList_VuoVideoFrame VuoListCreateWithCount_VuoVideoFrame | ( | const unsigned long | count, |
const VuoVideoFrame | value | ||
) |
Creates a new list of count
instances of value
.
Use this in conjunction with VuoListGetData_VuoVideoFrame to quickly initialize a large list.
void VuoListCut_VuoVideoFrame | ( | VuoList_VuoVideoFrame | list, |
const signed long | startIndex, | ||
const unsigned long | itemCount | ||
) |
Removes items from the list except those in the range specified by startIndex
and itemCount
.
void VuoListExchangeValues_VuoVideoFrame | ( | VuoList_VuoVideoFrame | list, |
const unsigned long | indexA, | ||
const unsigned long | indexB | ||
) |
Swaps the value at indexA
with the value at indexB
.
unsigned long VuoListGetCount_VuoVideoFrame | ( | const VuoList_VuoVideoFrame | list | ) |
Returns the number of elements in list
.
VuoVideoFrame* VuoListGetData_VuoVideoFrame | ( | const VuoList_VuoVideoFrame | 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.
VuoVideoFrame VuoListGetValue_VuoVideoFrame | ( | const VuoList_VuoVideoFrame | list, |
const unsigned long | index | ||
) |
Returns the VuoVideoFrame at index
.
Index values start at 1. If the list has no items, returns a default value. 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).
void VuoListInsertValue_VuoVideoFrame | ( | const VuoList_VuoVideoFrame | list, |
const VuoVideoFrame | value, | ||
const unsigned long | index | ||
) |
Inserts the VuoVideoFrame
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.
void VuoListPrependValue_VuoVideoFrame | ( | VuoList_VuoVideoFrame | list, |
const VuoVideoFrame | value | ||
) |
Prepends value
to list
.
void VuoListRemoveAll_VuoVideoFrame | ( | VuoList_VuoVideoFrame | list | ) |
Removes all values from list
.
void VuoListRemoveFirstValue_VuoVideoFrame | ( | VuoList_VuoVideoFrame | list | ) |
Removes the first value from list
.
void VuoListRemoveLastValue_VuoVideoFrame | ( | VuoList_VuoVideoFrame | list | ) |
Removes the last value from list
.
void VuoListRemoveValue_VuoVideoFrame | ( | VuoList_VuoVideoFrame | list, |
const unsigned long | index | ||
) |
Removes the VuoVideoFrame
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.
void VuoListReverse_VuoVideoFrame | ( | VuoList_VuoVideoFrame | list | ) |
Reverses the order of the items in list
.
void VuoListSetValue_VuoVideoFrame | ( | const VuoList_VuoVideoFrame | list, |
const VuoVideoFrame | value, | ||
const unsigned long | index | ||
) |
Changes the VuoVideoFrame at index
.
Index values start at 1. 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).
void VuoListShuffle_VuoVideoFrame | ( | VuoList_VuoVideoFrame | 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.
