Class: TMinutes

Declaration: TimeClasses.h

Taxonomy Categories:

Member Functions:

Interface Category:

API.

Inherits From:

TTime

Inherited By:

None.

Purpose:

A TTime derived class for minutes.

Instantiation:

Allocate on the heap or the stack.

Deriving Classes:

Derived classes must preserve the TTime and TMinutes interfaces.

Concurrency:

Not multithread safe.

Resource Use:

No special requirements.

Member Function: TMinutes::TMinutes

TMinutes ()
TMinutes (double numberOfMinutes)
TMinutes (const TTime & theTime)
TMinutes (const TMinutes & theMinutes)

Interface Category:

API.

Purpose:

Default constructor.
Initializes to the number of minutes to be represented.
Copy constructor for TTime or a derived class.
Copy constructor.

Calling Context:

Call this function directly.

Called by the stream-in operators and uninitialized objects.
Called to initialize to the number of minutes to be represented.
Called to copy a TTime or derived class.
Called to copy an object.

Parameters:

Takes no parameters.
double numberOfMinutes -The number of minutes to be represented.
const TTime & theTime -The object to copy.
const TMinutes & theMinutes -The object to copy.

Return Value:

None.

Exceptions:

Throws no exceptions, passes all exceptions through.

Concurrency:

Not multithread safe.

Other Considerations:

Can be safely type cast between TTime derived classes because no extra storage is added.

virtual ~ TMinutes ()

Interface Category:

API.

Purpose:

Destructor.

Calling Context:

Call this function directly. Called to destroy an object.

Parameters:

Purpose:

Assignment operator.

Calling Context:

Call this function directly. Called when an object is assigned to another compatible object.

Parameters:

const TMinutes & theMinutes -The source object for the assignment.
