    Struct AsyncOperationHandle<TObject>

    Handle for internal operations. This allows for reference counting and checking for valid references.

    Inherited Members
    ValueType.Equals(Object)
    ValueType.ToString()
    Object.Equals(Object, Object)
    Object.ReferenceEquals(Object, Object)
    Object.GetType()
    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

    Name Description
    DebugName

    Debug name of the operation.

    IsDone

    True if the operation is complete.

    OperationException

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

    PercentComplete

    The progress of the internal operation. This is evenly weighted between all sub-operations. For example, a LoadAssetAsync call could potentially be chained with InitializeAsync and have multiple dependent operations that download and load content. In that scenario, PercentComplete would reflect how far the overal operation was, and would not accurately represent just percent downloaded or percent loaded into memory. For accurate download percentages, use GetDownloadStatus().

    Result

    The result object of the operations.

    Status

    The status of the internal operation.

    Task

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

    Methods

    Name Description
    Equals(AsyncOperationHandle<TObject>)

    Provide equality for this struct.

    GetDependencies(List<AsyncOperationHandle>)

    Get dependency operations.

    GetDownloadStatus()

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

    GetHashCode()

    Get hash code of this struct.

    IsValid()

    Check if the handle references an internal operation.

    WaitForCompletion()

    Synchronously complete the async operation.

    Events

    Name Description
    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.

    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.

    Destroyed

    Event for handling the destruction of the operation.

    Operators

    Name Description
    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>()

    Explicit Interface Implementations

    Name Description
    IEnumerator.Current
    IEnumerator.MoveNext()

    Overload for MoveNext().

    IEnumerator.Reset()

    Overload for Reset().
