CompareHashes<TOldValue, TOldGetter, TNewValue, TNewGetter>(Int32, Void*, Int32, Void*, Int32*, Int32*, out Int32, out Int32)

Compare hashes of two collections and provide a list of indices removeIndices to remove in oldHashes and a list of indices addIndices to add in newHashes.

Assumes that newHashes and oldHashes are sorted.

Declaration

    where TOldValue : struct where TOldGetter : struct, CoreUnsafeUtils.IKeyGetter<TOldValue, Hash128> where TNewValue : struct where TNewGetter : struct, CoreUnsafeUtils.IKeyGetter<TNewValue, Hash128>
Parameters
Type Name Description
Int32 oldHashCount

Number of hashes in oldHashes.
Void* oldHashes

Previous hashes to compare.
Int32 newHashCount

Number of hashes in newHashes.
Void* newHashes

New hashes to compare.
Int32* addIndices

Indices of element to add in newHashes will be written here.
Int32* removeIndices

Indices of element to remove in oldHashes will be written here.
Int32 addCount

Number of elements to add will be written here.
Int32 remCount

Number of elements to remove will be written here.
Returns
Type Description
