public interface Profiler

Root profiler interface.

Profiler classes are expected to provide either a non-arg constructor, or a constructor accepting single String argument, as the option line. The treatment of option line is unspecified, and can be handled in profiler-specific way. Profiler constructors can throw ProfilerException if profiler cannot operate, either because of misconfiguration, or help message requested. The message in ProfilerException should clearly articulate the reason.

Profilers normally implement one of the subinterfaces.
