Detailed Description

template<class T>
class OFGlobal< T >

Template class which allows to declare global objects that are protected by a Mutex if used in multi-thread applications.

Must be compiled with -DWITH_THREADS for multi-thread-operation. Template class T must have copy constructor and assignment operator.

Constructor & Destructor Documentation

OFGlobal()

template<class T >

OFGlobal< T >::OFGlobal ( const T &  arg )

inline

constructor.

Parameters

arg	value to which this object is initialised

Member Function Documentation

get()

template<class T >

T OFGlobal< T >::get ( )

inline

returns the value of this object.

If compiled for multi-thread operation, access to the value of the object is protected by a Mutex. The result is returned by value, not by reference.

Returns

value of this object.

References OFMutex::lock(), OFGlobal< T >::theMutex, OFMutex::unlock(), and OFGlobal< T >::val.

set()

template<class T >

void OFGlobal< T >::set ( const T &  arg )

inline

assigns new value to this object.

If compiled for multi-thread operation, access to the value of the object is protected by a Mutex.

Parameters

arg

new value

References OFMutex::lock(), OFGlobal< T >::theMutex, OFMutex::unlock(), and OFGlobal< T >::val.

xget()

template<class T >

void OFGlobal< T >::xget ( T &  arg )

inline

gets the value of this object.

If compiled for multi-thread operation, access to the value of the object is protected by a Mutex.

Parameters

arg	return value is assigned to this parameter.
