Detailed Description

template<typename T> class log4cpp::threading::ThreadLocalDataHolder< T >

This class holds Thread local data of type T, i.e.

for each thread a ThreadLocalDataHolder holds 0 or 1 instance of T. The held object must be heap allocated and will be deleted upon termination of the thread to which it belongs.

for each thread a ThreadLocalDataHolder holds 0 or 1 instance of T. The held object must be heap allocated and will be deleted upon termination of the thread to wich it belongs. This is an omni_threads based equivalent of Boost.Threads thread_specific_ptr<T> class.

template<typename T > T* log4cpp::threading::ThreadLocalDataHolder< T >::get () const [inline]

template<typename T > T* log4cpp::threading::ThreadLocalDataHolder< T >::get () const [inline]

Obtains the Object held for the current thread. Returns:

a pointer to the held Object or NULL if no Object has been set for the current thread.

template<typename T > T* log4cpp::threading::ThreadLocalDataHolder< T >::get () const [inline]

Obtains the Object held for the current thread. Returns:

a pointer to the held Object or NULL if no Object has been set for the current thread.

template<typename T > T* log4cpp::threading::ThreadLocalDataHolder< T >::get () const [inline]

template<typename T > T* log4cpp::threading::ThreadLocalDataHolder< T >::get () const [inline]

template<typename T > T& log4cpp::threading::ThreadLocalDataHolder< T >::operator* () const [inline]

template<typename T > T& log4cpp::threading::ThreadLocalDataHolder< T >::operator* () const [inline]

Obtains the Object held for the current thread. Precondition:

get() != NULL

Returns:

a reference to the held Object.

template<typename T > T& log4cpp::threading::ThreadLocalDataHolder< T >::operator* () const [inline]

Obtains the Object held for the current thread. Precondition:

get() != NULL

Returns:

a reference to the held Object.

template<typename T > T* log4cpp::threading::ThreadLocalDataHolder< T >::operator-> () const [inline]

template<typename T > T* log4cpp::threading::ThreadLocalDataHolder< T >::operator-> () const [inline]

Obtains the Object held for the current thread. Initially each thread holds NULL.

Returns:

a pointer to the held Object or NULL if no Object has been set for the current thread.

template<typename T > T* log4cpp::threading::ThreadLocalDataHolder< T >::operator-> () const [inline]

Obtains the Object held for the current thread. Initially each thread holds NULL.

Returns:

a pointer to the held Object or NULL if no Object has been set for the current thread.

template<typename T > T* log4cpp::threading::ThreadLocalDataHolder< T >::operator-> () const [inline]

template<typename T > T* log4cpp::threading::ThreadLocalDataHolder< T >::operator-> () const [inline]

template<typename T > T* log4cpp::threading::ThreadLocalDataHolder< T >::release () [inline]

template<typename T > T* log4cpp::threading::ThreadLocalDataHolder< T >::release () [inline]

Releases the Object held for the current thread. Postcondition:

get() == NULL

Returns:

a pointer to the Object thas was held for the current thread or NULL if no Object was held.

template<typename T > T* log4cpp::threading::ThreadLocalDataHolder< T >::release () [inline]

Releases the Object held for the current thread. Postcondition:

get() == NULL

Returns:

a pointer to the Object thas was held for the current thread or NULL if no Object was held.

template<typename T > void log4cpp::threading::ThreadLocalDataHolder< T >::reset (T * p = NULL) [inline]

template<typename T > void log4cpp::threading::ThreadLocalDataHolder< T >::reset (T * p = NULL) [inline]

Sets a new Object to be held for the current thread. A previously set Object will be deleted.

Parameters:

p the new object to hold.

Postcondition:

get() == p

template<typename T > void log4cpp::threading::ThreadLocalDataHolder< T >::reset (T * p = NULL) [inline]

Sets a new Object to be held for the current thread. A previously set Object will be deleted.

Parameters:

p the new object to hold.

Postcondition:

get() == p

template<typename T > void log4cpp::threading::ThreadLocalDataHolder< T >::reset (T * p = NULL) [inline]
