# Added ability to resize strided arrays from ArrayExtractComponent
|
||
|
|
|
||
|
|
Previously, it was not possible to resize an `ArrayHandleStride` because
|
||
|
|
the operation is a bit ambiguous. The actual array is likely to be padded
|
||
|
|
by some amount, and there could be an unknown amount of space skipped at
|
||
|
|
the beginning.
|
||
|
|
|
||
|
|
However, there is a good reason to want to resize `ArrayHandleStride`. This
|
||
|
|
is the array used to implement the `ArrayExtractComponent` feature, and
|
||
|
|
this in turn is used when extracting arrays from an `UnknownArrayHandle`
|
||
|
|
whether independent or as an `ArrayHandleRecombineVec`.
|
||
|
|
|
||
|
|
The problem really happens when you create an array of an unknown type in
|
||
|
|
an `UnknownArrayHandle` (such as with `NewInstance`) and then use that as
|
||
|
|
an output to a worklet. Sure, you could use `ArrayHandle::Allocate` to
|
||
|
|
resize before getting the array, but that is awkward for programers.
|
||
|
|
Instead, allow the extracted arrays to be resized as normal output arrays
|
||
|
|
would be.
