Detailed Description

template<class Mutex>
class RWTCounter< Mutex >

Deprecated:

As of SourcePro 11.1, use RWAtomicCounter.

A class for maintaining a reference count that uses the template type as a lock for atomicity.

Generally, applications will use one of two typedefs provided by the Smart Pointer package. RWSafeCounter is a typedef for RWTCounter<RWMutexLock> and provides thread-safe reference counting. RWUnsafeCounter is a typedef for RWTCounter<RWNullMutexLock> and can be used for greater efficiency when thread safety is not required.

Constructor & Destructor Documentation

template<class Mutex >

RWTCounter< Mutex >::RWTCounter ( unsigned  initCount = 0 )

inline

Constructs a default instance (initializes the reference count). Throws no exceptions.

template<class Mutex >

RWTCounter< Mutex >::RWTCounter ( RWStaticCtor  )

inline

Constructs a static instance (does not initialize the reference count). Throws no exceptions.

template<class Mutex >

RWTCounter< Mutex >::RWTCounter ( const RWTCounter< Mutex > &  second )

inline

Does not copy the internal count. This method is provided as a convenience to derived classes.

Member Function Documentation

template<class Mutex >

RWTCounter< Mutex > & RWTCounter< Mutex >::operator= ( const RWTCounter< Mutex > &  second )

inline

Does not assign the internal count. This method is provided as a convenience to derived classes.
