-/*!
- \class TQMutexPool qmutexpool_p.h
- \brief The TQMutexPool class provides a pool of TQMutex objects.
-
- \internal
-
- \ingroup thread
-
- TQMutexPool is a convenience class that provides access to a fixed
- number of TQMutex objects.
-
- Typical use of a TQMutexPool is in situations where it is not
- possible or feasible to use one TQMutex for every protected object.
- The mutex pool will return a mutex based on the address of the
- object that needs protection.
-
- For example, consider this simple class:
-
- \code
- class Number {
- public:
- Number( double n ) : num ( n ) { }
-
- void setNumber( double n ) { num = n; }
- double number() const { return num; }
-
- private:
- double num;
- };
- \endcode
-
- Adding a TQMutex member to the Number class does not make sense,
- because it is so small. However, in order to ensure that access to
- each Number is protected, you need to use a mutex. In this case, a
- TQMutexPool would be ideal.
-
- Code to calculate the square of a number would then look something
- like this:
-
- \code
- void calcSquare( Number *num )
- {
- TQMutexLocker locker( mutexpool.get( num ) );
- num.setNumber( num.number() * num.number() );
- }
- \endcode
-
- This function will safely calculate the square of a number, since
- it uses a mutex from a TQMutexPool. The mutex is locked and
- unlocked automatically by the TQMutexLocker class. See the
- TQMutexLocker documentation for more details.
