Class AbstractCompiler

java.lang.Object

com.google.javascript.jscomp.AbstractCompiler

All Implemented Interfaces:

SourceExcerptProvider

Direct Known Subclasses:

Compiler

public abstract class AbstractCompiler
extends Object
implements SourceExcerptProvider

An abstract compiler, to help remove the circular dependency of passes on JSCompiler. This is an abstract class, so that we can make the methods package-private.

AbstractCompiler

public AbstractCompiler()

Method Detail

getInput

public abstract CompilerInput getInput(InputId inputId)

Looks up an input (possibly an externs input) by input id. May return null.

getTypeRegistry

public abstract JSTypeRegistry getTypeRegistry()

Gets a central registry of type information from the compiled JS.

getTopScope

public abstract Scope getTopScope()

Gets the top scope.

report

public abstract void report(JSError error)

Report an error or warning.

getCodingConvention

public abstract CodingConvention getCodingConvention()

Gets the current coding convention.

reportCodeChange

public abstract void reportCodeChange()

Report code changes. Passes should call reportCodeChange when they alter the JS tree. This is verified by CompilerTestCase. This allows us to optimize to a fixed point.

getReverseAbstractInterpreter

public abstract ReverseAbstractInterpreter getReverseAbstractInterpreter()

Get an interpreter for type analysis.

getErrorManager

public abstract ErrorManager getErrorManager()

Gets the error manager.

getProgress

public abstract double getProgress()

Returns:

a number in [0,1] range indicating an approximate progress of the last compile. Note this should only be used as a hint and no assumptions should be made on accuracy, even a completed compile may choose not to set this to 1.0 at the end.
