API.

Purpose:

Destructor.

Calling Context:

Called to destroy an object.

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.

Member Function: TThreadSchedule::operator<<=

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 TInvalidVersionError if a version mismatch occurs.

Concurrency:

Not multithread safe.

Other Considerations:

None.

Member Function: TThreadSchedule::TThreadSchedule

TThreadSchedule ()
TThreadSchedule (const TThreadSchedule & aThreadSchedule)

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 TThreadSchedule & aThreadSchedule -The object to be copied.

Return Value:

None.

Exceptions:

Throws no exceptions, passes all exceptions through.

Concurrency:

Not multithread safe.

Other Considerations:

This is a abstract base class.

Member Function: TThreadSchedule::operator=

TThreadSchedule & operator =(const TThreadSchedule & aThreadSchedule)

Interface Category:

API.

Purpose:

Assignment operator.

Calling Context:

Called when an object is assigned to another compatible object.

Parameters:

const TThreadSchedule & aThreadSchedule -The right-hand side object of the assignment operation.

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: TThreadSchedule::CreateCorrectTypeThreadSchedule

static TThreadSchedule * CreateCorrectTypeThreadSchedule (const TThreadHandle & aThreadHandle)

Interface Category:

API.

Purpose:

Creates a correct derived class of TThreadSchedule pertaining to a thread represented by aThreadHandle.

Calling Context:

Called to acquire a schedule for some thread.

Parameters:

const TThreadHandle & aThreadHandle -The thread for which the schedule is needed.

Return Value:

Returns a pointer to the newly created schedule object.

Exceptions:

Throws TUnknownSchedulingClassException::kUnknownSchedulingClass if the scheduling data for the thread in consideration doesn't belong to any of the CommonPoint-defined derived classes.

Concurrency:

Not multithread safe.

Other Considerations:

Storage space allocated should be deallocated by user.

Member Function: TThreadSchedule::GetPriority

virtual AbsolutePriority GetPriority () const
