Class InterpreterGenerator

java.lang.Object
  avrora.core.isdl.ast.StmtVisitor.DepthFirst
      avrora.core.isdl.gen.InterpreterGenerator

All Implemented Interfaces:: Architecture.EncodingVisitor, Architecture.InstrVisitor, Architecture.OperandVisitor, Architecture.SubroutineVisitor, Architecture.Visitor, StmtVisitor

Direct Known Subclasses:: FIFInterpreterGenerator

public class InterpreterGenerator
extends StmtVisitor.DepthFirst
implements Architecture.Visitor

The InterpreterGenerator class is a visitor over the code of an instruction declaration or subroutine that generates the appropriate Java code that implements an interpreter for the architecture.

Nested Class Summary
