Class Job

java.lang.Object

polyglot.frontend.Job

public class Job
extends java.lang.Object

A Job encapsulates work done by the compiler for a single compilation unit. A Job contains all information for a particular compilation unit carried between phases of the compiler. Only one pass should be run over a job at a time. TODO: The class should probably be renamed to, say, CompilationUnit.
