• C++ scoped static initialization is not thread-safe, on purpose!

class singleton { ... }; 
singleton& singleton::get_instance( ) 
{ 
        static singleton the_instance; 
        return the_instance; 
}

the above becomes:

if(!flag) 
{ 
        flag = true; 
        construct_object(); 
}

State vs. Strategy vs. Bridge

• "Strategy, State, Bridge (and to some degree Adapter) have similar solution structures. They all share elements of the "handle/body" idiom. They differ in intent - that is, they solve different problems." [Coplien, Advanced C++, p58]
  • A State object encapsulates a state-dependent behavior (and possibly state transitions)
  • A Strategy object encapsulates an algorithm
  • Bridge decouple an abstraction from its implementation so that the two can vary independently.

Interpreter vs. Visitor

Composite	Inteprepter

• Interpreter pattern builds on the existing infrastructure of Composite pattern.
