Declaration

public static NativeArray<T> ConvertExistingNativeListToNativeArray(ref NativeList`1 nativeList, int length, AllocatorHandle allocator);

Parameters

Parameter Description
nativeList NativeList to be converted.
length The count of elements.
allocator The Allocator to use.

Returns

NativeArray<T> Returns the NativeArray that was created.

Description

Convert NativeList into a NativeArray.

There is a caveat if users would like to transfer memory ownership from the NativeList to the converted NativeArray. NativeList implementation includes two memory allocations, one holds its header, another holds the list data. After convertion, the converted NativeArray holds the list data and dispose the array only free the list data. Users need to manually free the list header to avoid memory leaks, for example after convertion call, AllocatorManager.Free(allocator, nativeList.m_ListData);
