Member Functions:
Interface Category:
API.
Inherits From:
TTime
Inherited By:
None.
Purpose:
This concrete class is based on a reference time of midnight. Time is measured in seconds from the reference time. Instances of TSQLTime are intended for general use in alarms, or any other client context that demands a time based on the reference time.
Instantiation:
Allocate on the heap or the stack.
Deriving Classes:
None.
Concurrency:
Not multithread safe.
Resource Use:
No special requirements.
Other Considerations:
None.
- TSQLTime ()
- TSQLTime (const TSQLTime & time)
- TSQLTime (const TSQLDate & time)
- TSQLTime (const TSQLTimestamp & time)
- TSQLTime (double secs)
Interface Category:
API.
Purpose:
- Default constructor.
- Copy constructor.
- Constructs a time object from a date.
- Constructs a time object from a time stamp.
- Constructs a time object based on the elapsed seconds specified by the argument.
Calling Context:
- Called by the stream-in operators and any other function that needs to construct an uninitialized object.
- Called to copy an object.
- Called to construct an initialized object.
- Called to construct an initialized object.
- Called to construct an initialized object.
Parameters:
- Takes no parameters.
- const TSQLTime & time -The time object to copy.
- const TSQLDate & time -The date object to use in initializing this object.
- const TSQLTimestamp & time -The time stamp object to use in initializing this object.
- double secs -The elapsed time, in seconds.
Return Value:
None.
Exceptions:
Throws no exceptions, passes all exceptions through.
Concurrency:
Not multithread safe.
Other Considerations:
None.
virtual ~ TSQLTime ()
Interface Category:
API.
Purpose:
Destructor.
Calling Context:
Called to destroy an object.
Parameters:
Return Value:
None.
Exceptions:
Throws no exceptions, passes all exceptions through.

Other Considerations:
None.
Member Function: TSQLTime::operator=
TSQLTime & operator =(const TSQLTime &)
Interface Category:
API.
Purpose:
Assignment operator.
Calling Context:
Called when an object is assigned to another compatible object.
Parameters:
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.
