InstructionCount
class InstructionCount
API for gathering and querying instruction counts. Example usage:
Debug.InstructionCount icount = new Debug.InstructionCount();
icount.resetAndStart();
[... do lots of stuff ...]
if (icount.collect()) {
System.out.println("Total instructions executed: "
+ icount.globalTotal());
System.out.println("Method invocations: "
+ icount.globalMethodInvocations());
}
