public class Compiler

extends java.lang.Object

This is the main entry point for the compiler. It contains a work list that contains entries for all classes that must be compiled (or otherwise worked on).

Field Summary

protected NodeFactory	node_factory The node factory creates AST node objects.
protected SourceLoader	source_loader The source loader is responsible for loading source files from the source path.
protected TargetFactory	target_factory The target factory is responsible for naming and opening output files given a package name and a class or source file name.
protected TypeSystem	type_system The type system.

Constructor Summary

Compiler(Options options_)
Initialize the compiler.

Method Summary

void	addPass(Pass pass) Add a pass to the worklist.
boolean	compile(java.util.Collection sources) Compile all the files listed in the set of strings source.

protected boolean	finish() Run all jobs in the worklist to completion.
Job	jobForSource(Source source) Get a job for the source.
java.util.Collection	jobs() Return a collection of all jobs in the compilation.
LoadedClassResolver	loadedResolver() Get the compiler's parsed-file resolver
NodeFactory	nodeFactory() Get the compiler's node extension factory
java.util.Collection	outputFiles() Return a set of output filenames resulting from a compilation.
int	outputWidth() Maximum number of characters on each line of output
TableResolver	parsedResolver() Get the compiler's parsed-file resolver
boolean	readClass(java.lang.String className) Compile the source file for a given class to completion.
boolean	readSource(Source source) Compile a source file until the types in the source file are constructed.
static void	report(int level, java.lang.String msg) Debug reporting for the frontend.
static void	reportTime(int level, java.lang.String msg) Reports the time taken by every pass.
boolean	runToPass(Pass goal) Run all passes in the worklist until the goal pass completes.
boolean	serializeClassInfo() Should class info be serialized into the output?
SourceLoader	sourceLoader() Get the compiler's source loader

Parameters:

options - Contains jltools options

Method Detail

outputFiles

public java.util.Collection outputFiles()

Return a set of output filenames resulting from a compilation.

readSource

public boolean readSource(Source source)
                   throws java.io.IOException
