Interface Summary

Interface	Description
ExtensionInfo	ExtensionInfo is the main interface for defining language extensions.
FileSource	This interface is provided for backward compatibility.
JobExt	A JobExt encapsulates work done by the compiler on behalf of one source file.
Parser	A parser interface.
Pass	A Pass represents a compiler pass that runs on a Job.
Source	Interface for defining source files
SourceLoader	Interface for defining source file loader

Class Summary

Class	Description
AbstractExtensionInfo	This is an abstract ExtensionInfo.
AbstractPass	The base class for most passes.
Compiler	This is the main entry point for the compiler.
CupParser	A parser implemented with a Cup generated-parser.
EmptyPass	An EmptyPass does nothing.
JLExtensionInfo	This is the default ExtensionInfo for the Java language.
JLScheduler	Comment for Scheduler
JLVersion	Version information for the base compiler.
Job	A Job encapsulates work done by the compiler for a single compilation unit.
OutputPass	An output pass generates output code from the processed AST.
ParserlessJLExtensionInfo	This class implements most of the ExtensionInfo for the Java language.
ParserPass	A pass which runs a parser.
PrettyPrintPass	An output pass generates output code from the processed AST.
Scheduler	The Scheduler manages Goals and runs Passes.
Scheduler.TheEndGoal
Scheduler.TheEndGoal.EndPass
Source_c
Stats	Statistics collection and reporting object.
Stats.Times
TargetFactory	A TargetFactory is responsible for opening output files.
Topics	Extension information for jl extension.
VisitorPass	A pass which runs a visitor.

Enum Summary

Enum	Description
Source.Kind

Exception Summary

Exception	Description
CyclicDependencyException	Thrown during when the compiler tries to run a pass that is already running.
MissingDependencyException	A MissingDependencyException is thrown when a goal cannot be reached (yet) because the it is dependent on another, often just discovered, goal.
SchedulerException	A SchedulerException is a runtime exception that may abort a running pass and return the scheduler to the scheduling loop.

Package polyglot.frontend Description

Contains helper classes for the frontend that are used by polyglot.main. The Compiler class manages the input and output files and starts the compilation process for a given language extension. Language extensions implement the ExtensionInfo interface. The The class AbstractExtensionInfo contains code for invoking the individual passes of the extension. Subclasses of AbstractExtensionInfo define the passes for the extension. The base Java compiler is implemented in the polyglot.frontend.JLExtensionInfo class. Language extensions typically (but not necessarily) subclass polyglot.frontend.JLExtensionInfo.
