Detailed Description

template<class T>
class NLMISC::CUnfairSynchronized< T >

This class ensure that the Value is accessed by only one thread. First you have to create a CSynchronized class with you type. Then, if a thread want to modify or do anything on it, you create a CAccessor in a sub scope. You can modify the value of the CUnfairSynchronized using the value() function until the end of the scope. So you have to put the smaller scope as you can.

Internally, this class uses a CUnfairMutex object (see CUnfairMutex for programming considerations).

 // the value that you want to be thread safe.
 CUnfairSynchronized<int> val;
 { // create a new scope for the access
   // get an access to the value
   CUnfairSynchronized<int>::CAccessor acces(&val);
   // now, you have a thread safe access until the end of the scope, so you can do whatever you want. for example, change the value
   acces.value () = 10;
 } // end of the access
