3. Creation
timer
t(const string& name, bool report on destruction = true);
creates an instance t with the given name. If report on destruction
is true, then the timer reports upon its destruction how long it has
been running in total. The initial state of the timer is stopped.
timer t; creates an unnamed instance t and sets the report on destruction
flag to false. The initial state of the timer is stopped.
4. Operations
void t.reset( ) sets the internal counter and the total elapsed time to
zero.
void t.start( ) increments the internal counter.
void t.stop( ) decrements the internal counter. (If the counter is
already zero, nothing happens.)
void t.restart( ) short-hand for t.reset( ) + t.start( ).
void t.halt( ) sets the counter to zero, which forces the timer into
the state stopped no matter how many start operations
have been executed before.
bool t.is running( ) returns if t is currently in the state running.
float t.elapsed time( ) returns how long (in seconds) t has been in the state
running (since the last reset).
void
t.set name(const string& name)
sets the name of t.
string t.get name( ) returns the name of t.
void
t.report on desctruction(bool do report = true)
sets the flag report on destruction to do report.
bool t.will report on desctruction( )
5. Example
returns whether t will issue a report upon its destruction.
We give an example demonstrating the use of the class measure. Note that the function
below has several return statements, so it would be tedious to stop the timer “by hand”.
