~TCancelDelayToken
operator=
operator<<=
operator>>=

Interface Category:

API.

Inherits From:

MCollectible

Inherited By:

None.

Purpose:

This object is used by TDelay, and TClock and its derived classes. It is used to identify the delay to be canceled.

Instantiation:

Always allocate on the heap. Created by the clock ::CancelableDelayUntil function.

Deriving Classes:

Put whatever information is necessary for identifying a delay to be canceled.

Concurrency:

Not multithread safe.

Resource Use:

No special requirements.

Member Function: TCancelDelayToken::TCancelDelayToken

TCancelDelayToken ()
TCancelDelayToken (const TCancelDelayToken &)

Interface Category:

API.

Purpose:

Default constructor.
Copy constructor.

Calling Context:

Called by the stream-in operators.
Called to copy an object.

Parameters:

Takes no parameters.
const TCancelDelayToken & -The object to copy.

Return Value:

None.

Exceptions:

Throws no exceptions, passes all exceptions through.

Concurrency:

Not multithread safe.

Other Considerations:

Created by the clock function ::CancelableDelayUntil function.

Member Function: TCancelDelayToken::~TCancelDelayToken

virtual ~ TCancelDelayToken ()

Interface Category:

API.

Purpose:

Destructor.

Calling Context:

Called to destroy an object.

Parameters:

Takes no parameters.

Return Value:

None.

Exceptions:

Throws no exceptions, passes all exceptions through.

Concurrency:

Not multithread safe.

Other Considerations:

Called by the clock ::CancelDelay function.

Member Function: TCancelDelayToken::operator=

TCancelDelayToken & operator =(const TCancelDelayToken &)

Interface Category:

API.

Purpose:

Assignment operator.

Calling Context:

Called when an object is assigned to another compatible object.

Parameters:

const TCancelDelayToken & -The source object for the assignment.

Return Value:

A non-const reference to the left-hand side object.

Exceptions:

Throws no exceptions, passes all exceptions through.

Concurrency:

Not multithread safe.

Other Considerations:

None.

Member Function: TCancelDelayToken::operator<<=

virtual TStream & operator <<= (TStream & fromWhere)

Interface Category:

API.

Purpose:

Stream-in operator.

Calling Context:

Called to stream in data.

Parameters:

TStream & fromWhere -The stream the object streams itself in from.

Return Value:

Returns a reference to the stream the object streams itself in from.

Exceptions:

Throws no exceptions, passes all exceptions through.

Concurrency:

Not multithread safe.

Other Considerations:

Member Function: TCancelDelayToken::operator>>=

virtual TStream & operator >>=(TStream & toWhere) const

Interface Category:

API.

Purpose:

Stream-out operator.

Calling Context:

Called to stream out data.

Parameters:

TStream & toWhere -The stream the object streams itself out to.

Return Value:

Returns a reference to the stream the object streams itself out to.

Exceptions:

Throws no exceptions, passes all exceptions through.

Concurrency:

Not multithread safe.

Other Considerations:

None.
