Detailed Description

Synchronization object allowing to sleep for given timespan.

A bell is a synchronization object enabling one thread to sleep for a particular timespan.

Constructor & Destructor Documentation

Bell::Bell ( )

inline

Constructor.

Constructs a new bell; the newly created bell is, at first, disabled.

void Bell::ring ( )

Ring the bell.

Method called by the Bellringer once the waiting time passed. Wakes up the sleeping thread(s).

unsigned int Bell::residual ( )

Returns the residual waiting time.

Will use Bellringer::residual().

void Bell::set ( unsigned int ms )

Set the bell's waiting time.

This method can be used to set the desired waiting time.

Parameters

ms	Time in milliseconds; will be passed to Bellringer::job()

void Bell::sleep ( )

Sleep until the bell rings.

The bell needs to be configured via Bell::set() prior to calling this method and should not have rung already. (see Bell::residual()).

void Bell::sleep ( unsigned int ms )

static

Creates a temporary bell object and sleeps for the given timespan.

Parameters

ms	time in milliseconds
