Detailed Description

template<typename T>
class ScopedSetter< T >

ScopedSetter sets value to given variable and when goes out of scope, reset its original state.

 // assume bool member variable m_isSet == true
 ...
 std::cout << (m_isSet ? "true" : "false") << std::endl; // print 'true'
 {     
     SCOPED_SETTER(bool, m_isSet, false); // false is required state
     std::cout << (m_isSet ? "true" : "false") << std::endl; // print 'false'
 } // end of scope - return orig state
 
 std::cout << (m_isSet ? "true" : "false") << std::endl; // print 'true'
