Taxonomy Categories:
Member Functions:
Interface Category:
API.
Inherits From:
TTime
Inherited By:
None.
Purpose:
A TTime derived class for hours.
Instantiation:
Allocate on the heap or the stack.
Deriving Classes:
Derived classes must preserve the TTime and THours interfaces.
Concurrency:
Not multithread safe.
Resource Use:
No special requirements.
- THours ()
- THours (double numberOfHours)
- THours (const TTime & theTime)
- THours (const THours & theHours)
Interface Category:
API.
Purpose:
- Default constructor.
- Initializes with the number of hours to represented by the object.
- Copy constructor for TTime and derived classes.
- Copy constructor.
Calling Context:
Call this function directly.
- Called by the stream-in operators and uninitialized objects.
- Called to initialize with the hours to be represented.
- Called to copy a TTime or derived class.
- Called to copy an object.
Parameters:
- Takes no parameters.
- double numberOfHours -The number of hours to be represented.
- const TTime & theTime -The object to copy.
- const THours & theHours -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 ~ THours ()
Interface Category:
API.
Purpose:
Destructor.
Calling Context:
Call this function directly.
Called to destroy an object.
Parameters:
Return Value:
None.
Exceptions:
Throws no exceptions, passes all exceptions through.
Concurrency:
Not multithread safe.
Other Considerations:
None.
Member Function: THours::GetHours
double GetHours () const
Interface Category:
API.
Purpose:
Gets the number of hours represented.
Calling Context:
Call this function directly.
Called to get a double of the number of hours.
Parameters:
Return Value:
Hours.
Exceptions:
Throws no exceptions, passes all exceptions through.
Concurrency:
Not multithread safe.
Other Considerations:
Returns a double that could be a NaN, or positive or negative infinity, depending on the time.
Member Function: THours::operator=
THours & operator =(const THours & theHours)
Interface Category:
API.
Purpose:
Assignment operator.
Calling Context:
Call this function directly.
Called when an object is assigned to another compatible object.
Parameters:
- const THours & theHours -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.
