Tools.h++ Class Reference

Return the current setting for the benchmark test duration. This should not be confused with function time() which
returns the actual test time.
virtual void
go();
Call this function to run the benchmark.
virtual void
idleLoop(unsigned long N);
This function can help to correct the benchmark for overhead. The default definition merely executes a "for()" loop N
times. See the example.
const char *
machine();
This function accesses the name of the machine which is passed into the benchmark object through parse().
virtual void
parse(int argc, char* argv[]);
This function allows an easy way to change the test duration, number of inner loops and machine description from the
command line:
Argument Type Description
argv[1] double Duration (sec.)
argv[2] unsigned long No. of inner loops
argv[3] const char* Machine
void
parse(const char *);
This is a non-virtual function which provides the same service as parse(int argc, char * argv[]), but is designed for
Windows users. It extracts tokens from the null-terminated command argument provided by Windows, then calls the
virtual parse for ANSI C command arguments.
virtual void
report(ostream&) const;
Calling this function provides an easy and convenient way of getting an overall summary of the results of a benchmark.
double
setDuration(double t);
Change the test duration to time t.
unsigned long
setInnerLoops(unsigned long N);
Change the number of "inner loop operations" to N.
virtual void
what(ostream&) const;
You can supply a specializing version of this virtual function that provides some detail of what is being benchmarked.
It is called by report() when generating a standard report.
void
where(ostream&) const;
This function will print information to the stream about the compiler and memory model that the code was compiled
under.
unsigned long
innerLoops() const;
