Constructor Detail

InterpreterGenerator

public InterpreterGenerator(Architecture a,
                            Printer p)

The constructor for the InterpreterGenerator class builds an object capable of generating the interpreter for a particular architecture that outputs to the specified printer. In this implementation, the interpreter generator simply outputs visit() methods for each instruction that are meant to be pasted into a template file containing the rest of the interpreter. This can be done by constructing a SectionFile instance.

Parameters:

a - the architecture to generate an interrupter for

p - a printer to output the code implementing the interpreter
