Utilities for copying native arrays.

Inheritance

Namespace: UnityEngine.XR.ARSubsystems

Syntax

public static class NativeCopyUtility : object

Methods

PtrToNativeArrayWithDefault<T>(T, Void*, Int32, Int32, Allocator)

Creates a NativeArray from a pointer by first copying length defaultTs into the NativeArray, and then overwriting the data in the array with source, assuming each element in source is sourceElementSize bytes.

Declaration

public static NativeArray<T> PtrToNativeArrayWithDefault<T>(T defaultT, void *source, int sourceElementSize, int length, Allocator allocator)
    where T : struct

Parameters

Type	Name	Description
T	defaultT	A default version of T, which will be used to first fill the array before copying from source.
Void*	source	A pointer to a contiguous block of data of size sourceElementSize * length.
Int32	sourceElementSize	The size of one element in source.
Int32	length	The number of elements to copy.
Allocator	allocator	The allocator to use when creating the NativeArray.

Returns

Type	Description
NativeArray<T>	A new NativeArray populating with defaultT and source. The caller owns the memory.

Type Parameters

Name	Description
T	The type of struct to copy.

Remarks

This is useful for native interops with structs that may change over time. This allows new fields to be added to the C# struct without breaking data obtained from data calls.
