Constructor & Destructor Documentation

ABA_COWTIMER::ABA_COWTIMER

(

ABA_GLOBAL *

glob

)

After the application of the constructor the timer is not running, i.e., to measure time it has to be started explicitly.

We initialize base time with the current time, such that later we can convert the time to seconds without arithmetic overflow. The function time() is defined in the standard /-library.

Parameters:

glob

A pointer to a global object.

ABA_COWTIMER::ABA_COWTIMER	(	ABA_GLOBAL *	glob,
		long	secs
	)

This constructor initializes the total time of the timer.

The timer is not running, too.

Parameters:

	glob	A pointer to a global object.
	centiSeconds	The initial value of the timer in seconds.

virtual ABA_COWTIMER::~ABA_COWTIMER

(

)

[virtual]

The destructor.

Member Function Documentation

virtual long ABA_COWTIMER::theTime

(

)

const [private, virtual]

Returns the wall clock time since the initialization of the timer in seconds.

This function redefines the pure virtual function of the base class ABA_TIMER.

The function theTime() uses the function times(), which returns the elapsed real time in clock ticks.

Implements ABA_TIMER.

Member Data Documentation

long ABA_COWTIMER::baseTime_ [private]

Stores the result of a call to the function time(NULL) at construction time.

We require this member such that we can return the time in centiseconds correctly in the function theTime(). Otherwise, an arithmetic overflow can occur.
