Struct NativeReference<T>
An unmanaged single value.
Namespace: Unity.Collections
Syntax
[NativeContainer]
public struct NativeReference<T> : INativeDisposable, IDisposable, IEquatable<NativeReference<T>> where T : structType Parameters
| Name | Description |
|---|---|
| T | The type of value. |
Remarks
The functional equivalent of an array of length 1. When you need just one value, NativeReference can be preferable to an array because it better conveys the intent.

NativeReference(AllocatorManager.AllocatorHandle, NativeArrayOptions)
Initializes and returns an instance of NativeReference.
Declaration
public NativeReference(AllocatorManager.AllocatorHandle allocator, NativeArrayOptions options = NativeArrayOptions.ClearMemory)Parameters
| Type | Name | Description |
|---|---|---|
| AllocatorManager.AllocatorHandle | allocator | The allocator to use. |

| Type | Name | Description |
|---|---|---|
| NativeReference<T> | reference | The reference to copy to. |
Dispose()
Releases all resources (memory and safety handles).
Declaration
public void Dispose()Dispose(JobHandle)
Creates and schedules a job that will release all resources (memory and safety handles) of this reference.
Declaration
public JobHandle Dispose(JobHandle inputDeps)Parameters

Implements
Equals(Object)
Returns true if the value stored in this reference is equal to an object.
Declaration
[ExcludeFromBurstCompatTesting("Takes managed object")]
public override bool Equals(object obj)Parameters
| Type | Name | Description |
|---|---|---|
| Object | obj | An object to compare with. |
Returns
| Type | Description |
|---|---|
| Boolean | True if the value stored in this reference is equal to the object. |
Overrides
Remarks
Can only be equal if the object is itself a NativeReference.
Equals(NativeReference<T>)
Returns true if the value stored in this reference is equal to the value stored in another reference.
Declaration
