Class JavaToJavaScriptCompiler

java.lang.Object

com.google.gwt.dev.jjs.JavaToJavaScriptCompiler

public final class JavaToJavaScriptCompiler
extends Object

A base for classes that compile Java JProgram representations into corresponding Js source.
Work is split between a precompile() stage which is only called once and compilePerms() stage which is called once per permutation. This allow build systems the option of distributing and parallelizing some of the work.

Method Summary

Modifier and Type	Method and Description
static PermutationResult	compilePermutation(UnifiedAst unifiedAst, TreeLogger logger, CompilerContext compilerContext, Permutation permutation) Compiles a particular permutation.
protected ResolveRuntimeTypeReferences.TypeMapper<?>	normalizeSemantics() Transform patterns that can't be represented in JS (such as multiple catch blocks) into equivalent but compatible patterns and take JVM semantics (such as numeric casts) that are not explicit in the AST and make them explicit. These passes can not be reordering because of subtle interdependencies.

Method Detail

precompile

public static UnifiedAst precompile(TreeLogger logger,
                                    CompilerContext compilerContext,
                                    PrecompilationContext precompilationContext)
                             throws UnableToCompleteException

Throws:

UnableToCompleteException

compilePermutation

public static PermutationResult compilePermutation(UnifiedAst unifiedAst,
                                                   TreeLogger logger,
                                                   CompilerContext compilerContext,
                                                   Permutation permutation)
                                            throws UnableToCompleteException

Compiles a particular permutation.

Parameters:

logger - the logger to use

compilerContext - shared read only compiler state

permutation - the permutation to compile

Returns:

the permutation result

Throws:

UnableToCompleteException - if an error other than OutOfMemoryError occurs

normalizeSemantics

protected ResolveRuntimeTypeReferences.TypeMapper<?> normalizeSemantics()

Transform patterns that can't be represented in JS (such as multiple catch blocks) into equivalent but compatible patterns and take JVM semantics (such as numeric casts) that are not explicit in the AST and make them explicit.
These passes can not be reordering because of subtle interdependencies.
