#include <Timing.h>
Detailed Description
A timing and profiling class.
The times are added to accounts. Use start() to enter a new frame and stop(account) to leave it, adding spent time to the account and go back to the previous frame (therefore recursion is allowed). The MISC account is used starting and stopping the overall timing process and WHOLE is used for storing the summed up total runtime.
Member Enumeration Documentation
Definition of all available timing accounts.
_ACMAX is used internally and must not be used as account.
