Any magic, sufficiently analyzed is indistinguishable from technology. 

Here will take a look at how Typhoon assemblies are implemented. This information is not necessary for normal use of Typhoon, but may be useful for contributors or the just plain curious.

#Assembly Instrumentation

Typhoon uses a programming paradigm called Aspect Oriented Programming (AOP) to instrument the methods of your assembly classes with additional behavior.

AOP is used to encapsulate "cross-cutting" concerns. These are the kind of requirements that "cut across" many modules in your system. In our case the requirement is:


Whenever a new definition is created it should be assigned
a unique key based on the method name that defined it. 

Assembly AOP

AOP defines the following kinds of method interceptions:

Interception Description
Before Additional behavior is added before a method invocation.
After Additional behavior is added after a method invocation.
After Throwing Additional behavior is added after an exception occurs.
Around A flexible style that can be used to model any of the above.

TyphoonAssembly instrumentation uses the 'After' style - after a definition is returned it as allocated a unique key based on the method name that defined it.
