Flow.apex is created to simplify the creation of a Function. It simulates the procedural invocation of Functions, and weave them to build a larger and more complicated Function. Flow.apex acts as a bridge between the small Funcs and big custom Funcs that you create by subclassing Func.
Flow.apex offers a fluent API to build a custom Func without subclassing Func.
Flow.apex has adequate block structures to help weaving your Funcs.
Flow.apex enables a mechanism to support embedded scripting in Flows.
It is the cousin of R.apex, only more powerful.
Flow.apex uses procedral structures to build Funcs in the form of Flows.
Flow.apex not only creates Funcs, but also creates executable blocks of code.
Flow.apex includes a script that naturally integrates with R.apex and all of your Funcs.
