// This header is used to include the core portions of the calculator
|

|
// framework. The comments that follow describe the main classes within
|
||
|
|
// the framework and how they interact.
|
||
|
|
//
|
||
|
|
// Calculator: A class which clients subclass to do actual work.
|
||
|
|
// It receives input and produces output which may go to many other
|
||
|
|
// Calculators connected in a directed acyclic graph.
|
||
|
|
//
|
||
|
|
// CalculatorGraph: A class which sets up a CalculatorGraphConfig and
|
||
|
|
// runs it. This is the controller class which governs the top level
|
||
|
|
// behavior of the framework and how things are run.
|
||
|
|
//
|
||
|
|
// CalculatorNode: A class which keeps track of a single Calculator and
|
||
|
|
// framework level details that the client does not need to worry about
|
||
|
|
// (such as how to advertise that the Calculator is blocked or unblocked).
|
||
|
|
//
|
||
|
|
// InputStream: A class which holds the next value in an input stream
|
||
|
|
// for a Calculator to use and provides access to the stream header.
|
||
|
|
// It is the superclass of InputStreamImpl which holds implementation
|
||
|
|
// details for the framework.
|
||
|
|
//
|
||
|
|
// InputStreamImpl: All information for the input stream.
|
||
|
|
// A CalculatorNode and OutputStreamImpl has access to this information,
|
||
|
|
// but the Calculator does not.
|
||
|
|
//
|
||
|
|
// OutputStream: A class which gets the output packets from a Calculator
|
||
|
|
// and relays them to the next calculators or the framework.
|
||
|
|
//
|
||
|
|
// OutputStreamImpl: The framework level information for an OutputStream.
|
||
|
|
// A CalculatorNode has access to this information but the Calculator
|
||
|
|
// does not.
|
||
|
|
//
|
||
|
|
// CalculatorState: Data class to hold information the Calculator needs
|
||
|
|
// access to. This data persists across multiple runs of the graph,
|
||
|
|
// whereas the Calculators will be destroyed and recreated.
