Syntax

public abstract class AsyncOperationBase<TObject> : IAsyncOperation

Type Parameters

Name	Description
TObject	The type of the operation.

Constructors

AsyncOperationBase()

Basic constructor for AsyncOperationBase.

Declaration

protected AsyncOperationBase()

Properties

DebugName

A custom operation should override this method to provide a debug friendly name for the operation.

Declaration

protected virtual string DebugName { get; }

Property Value

Type	Description
String

Progress

A custom operation should override this method to return the progress of the operation.

Declaration

protected virtual float Progress { get; }

Property Value

Type	Description
Single	Progress of the operation. Value should be between 0.0f and 1.0f

Result

Accessor to Result of the operation.

Declaration

public TObject Result { get; set; }

Property Value

Type	Description
TObject

Methods

Complete(TObject, Boolean, String)

Complete the operation and invoke events.

Declaration

public void Complete(TObject result, bool success, string errorMsg)

Parameters

Type	Name	Description
TObject	result	The result object for the operation.
Boolean	success	True if successful or if the operation failed silently.
String	errorMsg	The error message if the operation has failed.

Remarks

An operation is considered to have failed silently if success is true and if errorMsg isn't null or empty. The exception handler will be called in cases of silent failures. Any failed operations will call Release on any dependencies that succeeded.

Complete(TObject, Boolean, String, Boolean)

Complete the operation and invoke events.

Declaration

public void Complete(TObject result, bool success, string errorMsg, bool releaseDependenciesOnFailure)

Parameters

Type	Name	Description
TObject	result	The result object for the operation.
Boolean	success	True if successful or if the operation failed silently.
String	errorMsg	The error message if the operation has failed.
Boolean	releaseDependenciesOnFailure	When true, failed operations will release any dependencies that succeeded.

Remarks

An operation is considered to have failed silently if success is true and if errorMsg isn't null or empty. The exception handler will be called in cases of silent failures.

Destroy()

This will be called by the resource manager when the reference count of the operation reaches zero. This method should not be called manually. A custom operation should override this method and release any held resources

Declaration

protected virtual void Destroy()

Execute()

This will be called by the resource manager after all dependent operation complete. This method should not be called manually. A custom operation should override this method and begin work when it is called.

Declaration

protected abstract void Execute()

GetDependencies(List<AsyncOperationHandle>)

A custom operation should override this method to provide a list of AsyncOperationHandles that it depends on.

Declaration

protected virtual void GetDependencies(List<AsyncOperationHandle> dependencies)

Parameters

Type	Name	Description
List<AsyncOperationHandle>	dependencies	The list that should be populated with dependent AsyncOperationHandles.

ToString()

Converts the information about the operation to a formatted string.

Declaration

public override string ToString()

Returns

Type	Description
String	Returns the information about the operation.

Overrides

Object.ToString()
