Class Counters
java.lang.Object
harpoon.Runtime.Counters
public class Counters
- extends Object
Counters uses reflection to provide a very light-weight
counter package -- light-weight in terms of FLEX code required to
add/enable counters, not necessarily light-weight in terms of
execution time. All counters are thread-safe. We use reflection
at initialization time and at program termination to initialize
and report counter values, which minimizes the amount of
counter-specific code generation required by the FLEX side of
this. No special runtime support is required.
The dynamic generation of counter fields in this class is
handled by harpoon.Analysis.Counters.CounterFactory.
There is a HCodeFactory in this class which must be
included as a compilation pass to generate the proper calls to
the report() method at program's end.
