An implementation of a TimerCallback that provides a simple counter.

All of the functions in this class are thread-safe so that multiple threads can be accessing the Counter at the same time.

Member Function Documentation

void GNE::Counter::adjustCount

(

int

val

)

Adjusts the counter's value by adding val to the current count.

This means that negative numbers will subtract from the current count.

Counter::sptr GNE::Counter::create

(

)

[static]

Create a Counter.

Pass this Counter into a Timer class to use it.

See also:

TimerCallback

void GNE::Counter::setCount

(

int

newCount

)

Sets the current count to newCount.

Parameters:

newCount

the new value for the Counter

void GNE::Counter::timerCallback

(

)

[virtual]

The callback function that the Timer calls.

You should not call this function directly.

Implements GNE::TimerCallback.

void GNE::Counter::waitAndDecrement

(

)

This method blocks until the count is greater than zero.

If the count is already greater than zero it returns immediately. In either case, the value of the counter is decremented.
