# sc\_Timer(3)

The Timer class uses RegionTimer to time intervals in an exception safe manner.

## NAME

sc::Timer - The **Timer** class uses **RegionTimer** to time intervals in an exception safe manner.

## SYNOPSIS

`#include <regtime.h>`

### Public Member Functions

**Timer** (const char \*name)\
 Start timing a region using the default **RegionTimer** and activate the timer.  **Timer** (const **Ref**\< **RegionTimer** \> &, const char \*name)\
 Start timing a region using the given **RegionTimer**.  **~Timer** ()\
 Stop timing a region, if active.  void **reset** (const char \*=0)\
 Stop timing the current region, if active.

## Detailed Description

The **Timer** class uses **RegionTimer** to time intervals in an exception safe manner.

It will automatically call RegionTimer::enter when its constructor is called and RegionTimer::exit when its destructor is called. The reset member can also result in **RegionTimer**'s enter and exit routines being called. The programmer is responsible for making sure that timers are exited in the reverse of the order that they are entered. \

### sc::Timer::Timer (const Ref\< RegionTimer \> &, const char \* name)

Start timing a region using the given **RegionTimer**. If a null name pointer is given, then the timer will not be activated.
