Detailed Description

template<class GUARD>
class SharedSynchronize< GUARD >

Shared synchronization.

This class is used to synchronize executing contexts (shared) with a guard object of your choice. Some guard classes may implement the shared locks using exclusive locks.

class MyResource : public Object {
private:
 
  ReadWriteLock guard;
public:
 
  void myFirstMethod() const
  {
    SynchronizeShared<ReadWriteLock> synchronizeShared(guard);
    // do something as long as it doesn't modify the object
    if (earlyReturn) {
      return; // no need to explicitly release guard
    }
    bassert(!somethingWentWrong, MyResourceException()); // no need to explicitly release guard
  }
 
  void mySecondMethod()
  {
    ExclusiveExclusive<ReadWriteLock> exclusiveShared(guard);
    // do modification of object
    if (earlyReturn) {
      return; // no need to explicitly release guard
    }
    bassert(!somethingWentWrong, MyResourceException()); // no need to explicitly release guard
  }
};
