Detailed Description

A condition variable to allow synchronization between threads.

Condition variables are synchronization primitives to allow threads to wait until a particular condition occurs.

Member Function Documentation

virtual void ICond::broadcast ( )

pure virtual

Resumes all threads that are waiting for the condition.

Calling the method without no threads waiting for signals have no effect.

virtual void ICond::signal ( )

pure virtual

Resumes at least one single thread that is waiting for the condition.

Calling the method without no threads waiting for signals have no effect.

virtual void ICond::wait ( IMutex *  mutex )

pure virtual

The calling thread will wait until the condition variable is signaled by another thread.

This method atomically performs this steps:

• unlocks the passed mutex.
• wait for a signal from another thread (see methods signal and broadcast).
• locks again the mutex.

Parameters

mutex

The mutex to be unlocked/locked.

Precondition

1. The passed mutex is currently locked by the calling thread.

Postcondition

1. The passed mutex is locked back by the calling thread.
