Namespace: UnityEngine.ResourceManagement.AsyncOperations

Syntax

public struct AsyncOperationHandle<TObject> : IEnumerator, IEquatable<AsyncOperationHandle<TObject>>

Type Parameters

Name	Description
TObject	The object type of the underlying operation.

Properties

DebugName

Debug name of the operation.

Declaration

public string DebugName { get; }

Property Value

Type	Description
String

IsDone

True if the operation is complete.

Declaration

public bool IsDone { get; }

Property Value

Type	Description
Boolean

OperationException

The exception for a failed operation. This will be null unless Status is failed.

Declaration

public Exception OperationException { get; }

Property Value

Type	Description
Exception

PercentComplete

The progress of the internal operation.

Declaration

public float PercentComplete { get; }

Property Value

Type	Description
Single

Result

The result object of the operations.

Declaration

public TObject Result { get; }

Property Value

Type	Description
TObject

Status

The status of the internal operation.

Declaration

public AsyncOperationStatus Status { get; }

Property Value

Type	Description
AsyncOperationStatus

Task

Return a Task object to wait on when using async await.

Declaration

public Task<TObject> Task { get; }

Property Value

Type	Description
Task<TObject>

Methods

Equals(AsyncOperationHandle<TObject>)

Provide equality for this struct.

Declaration

public bool Equals(AsyncOperationHandle<TObject> other)

Parameters

Type	Name	Description
AsyncOperationHandle<TObject>	other	The operation to compare to.

Returns

Type	Description
Boolean

Implements

IEquatable<T>.Equals(T)

GetDownloadStatus()

Return the current download status for this operation and its dependencies.

Declaration

public DownloadStatus GetDownloadStatus()

Returns

Type	Description
DownloadStatus	The download status.

GetHashCode()

Get hash code of this struct.

Declaration

public override int GetHashCode()

Returns

Type	Description
Int32

Overrides

ValueType.GetHashCode()

IsValid()

Check if the handle references an internal operation.

Declaration

public bool IsValid()

Returns

Type	Description
Boolean	True if valid.

Events

Completed

Completion event for the internal operation. If this is assigned on a completed operation, the callback is deferred until the LateUpdate of the current frame.

Declaration

public event Action<AsyncOperationHandle<TObject>> Completed

Event Type

Type	Description
Action<AsyncOperationHandle<TObject>>

CompletedTypeless

Completion event for non-typed callback handlers. If this is assigned on a completed operation, the callback is deferred until the LateUpdate of the current frame.

Declaration

public event Action<AsyncOperationHandle> CompletedTypeless

Event Type

Type	Description
Action<AsyncOperationHandle>

Destroyed

Event for handling the destruction of the operation.

Declaration

public event Action<AsyncOperationHandle> Destroyed

Event Type

Type	Description
Action<AsyncOperationHandle>

Operators

Implicit(AsyncOperationHandle<TObject> to AsyncOperationHandle)

Conversion from typed to non typed handles. This does not increment the reference count. To convert from non-typed back, use AsyncOperationHandle.Convert<T>()

Declaration

public static implicit operator AsyncOperationHandle(AsyncOperationHandle<TObject> obj)

Parameters

Type	Name	Description
AsyncOperationHandle<TObject>	obj	The typed handle to convert.

Returns

Type	Description
AsyncOperationHandle	Returns the converted operation handle.
