Detailed Description

Thread-safe counter with capability to wait for zero value.

It is extendible through re-implementation of virtual methods.

Member Function Documentation

dec()

virtual int Arc::SimpleCounter::dec ( void  )

virtual

Decrement value of counter.

Returns

new value. Does not go below 0 value.

forceReset()

virtual void Arc::SimpleCounter::forceReset ( void  )

inlinevirtual

This method is meant to be used only after fork.

It resets state of all internal locks and variables.

get()

virtual int Arc::SimpleCounter::get ( void  ) const

virtual

Returns

current value of counter.

inc()

virtual int Arc::SimpleCounter::inc ( void  )

virtual

Increment value of counter.

Returns

new value.

set()

virtual int Arc::SimpleCounter::set ( int  v )

virtual

Set value of counter.

Returns

new value.

wait() [1/2]

virtual void Arc::SimpleCounter::wait ( void  ) const

virtual

Wait for zero condition.

wait() [2/2]

virtual bool Arc::SimpleCounter::wait ( int  t ) const

virtual

Wait for zero condition no longer than t milliseconds.

If t is negative - wait forever.

Returns

false if timeout occurred.
