Class Summary

Class	Description
ArrayNormalizer	Replace array accesses and instantiations with calls to the Array class.
AssertionNormalizer	Replaces all assertion statements in the AST with if statements.
AssertionRemover	Removes all assertion statements from the AST.
AstDumper	A simple utility to dump a JProgram to a temp file, which can be called sequentially during a compilation/optimization run, so intermediate steps can be compared.
AutoboxUtils	Utilities for managing autoboxing of Java primitive types.
CatchBlockNormalizer	Merge multi-catch blocks into a single catch block that uses instanceof tests to determine which user block to run.
CloneExpressionVisitor	A general purpose expression cloner.
CompileTimeConstantsReplacer	Replaces compile time constants by their values.
CompoundAssignmentNormalizer	Replace problematic compound assignments with a sequence of simpler operations, all of which are either simple assignments or are non-assigning operations.
ComputeCastabilityInformation	Builds minimal cast maps to cover cast and instanceof operations.
ComputeExhaustiveCastabilityInformation	Builds exhaustive cast maps for class types defined in and array types used in this library.
ComputeInstantiatedJsoInterfaces	Record all Cast operations on JSOs as instantiations.
ComputePotentiallyObservableUninitializedValues	Determines conservatively which classes can potentially see uninitialized values of their subclasses' fields.
ControlFlowAnalyzer	This class finds out what code in a program is live based on starting execution at a specified location.
DeadCodeElimination	Removes certain kinds of dead code, and simplifies certain expressions.
DeadCodeElimination.FindBreakContinueStatementsVisitor	Examines code to find out whether it contains any break or continue statements.
Devirtualizer	Devirtualization is the process of converting virtual method calls on instances that might be a JSO, a string or and array (like "obj.doFoo();") to static calls (like "SomeClass.doFoo__devirtual$(obj)).
EnumOrdinalizer	This optimizer replaces enum constants with their ordinal value (a simple int) when possible.
EnumOrdinalizer.Tracker	A simple Tracker class for compiling lists of enum classes processed by this optimizer.
EqualityNormalizer	Rewrite Java == so that it will execute correctly in JavaScript.
ExpressionAnalyzer	Analyzes an expression and make a number of static analysis flags available based on the information available solely through the expression.
Finalizer	Finds all items are effectively final.
FixAssignmentsToUnboxOrCast	Most autoboxing is handled by GenerateJavaAST.
GenerateJavaScriptAST	Creates a JavaScript AST from a JProgram node.
GwtAstBuilder	Constructs a GWT Java AST from a single isolated compilation unit.
HandleCrossFragmentReferences	Rewrite JavaScript to better handle references from one code fragment to another.
ImplementCastsAndTypeChecks	Replace cast and instanceof operations with calls to the Cast class.
ImplementClassLiteralsAsFields	Create fields to represent the mechanical implementation of class literals.
ImplicitUpcastAnalyzer	This class will identify instances of an implicit upcast between non-primitive types, and call the overridable processImplicitUpcast method.
JavaToJavaScriptMapImpl	The default implementation of a JavaToJavaScriptMap.
JjsUtils	General utilities related to Java AST manipulation.
JModVisitorWithTemporaryVariableCreation	A JModVisitor capable of creating temporary local variables and placing their declarations in an appropriate preceding place.
JsAbstractTextTransformer	Base class for transforming program text.
JsFunctionClusterer	Re-orders function declarations according to a given metric and clustering algorithm in order to boost gzip/deflation compression efficiency.
JsniRefLookup	Deprecated find alternatives, only a couple of corner cases use this now.
JsniRestrictionChecker	Checks and throws errors for invalid JSNI constructs.
JsNoopTransformer	A TextTransformer that makes no modifications.
JsTypeLinker	Transforms program JS source by performing a per-type link.
LongCastNormalizer	Synthesize explicit casts to and from the primitive long type where such a cast would have been implicit.
LongEmulationNormalizer	Replaces long operations with calls to the emulation library.
MakeCallsStatic	This is an interesting "optimization".
MethodCallSpecializer	For each JMethodCall that contains a specialization, retarget the method to the specialized call if possible.
MethodCallTightener	Update polymorphic method calls to tighter bindings based on the type of the qualifier.
MethodInliner	Inline methods that can be inlined.
OptimizerStats	Stores statistics on the results of running an optimizer pass.
PostOptimizationCompoundAssignmentNormalizer	Normalize compound assignments as needed after optimization.
Pruner	Remove globally unreferenced classes, interfaces, methods, parameters, and fields from the AST.
ReboundTypeRecorder	Records all rebinds in an AST that has not been unified.
RecordRebinds	Records all live rebinds.
ReferenceMapper	Creates unresolved references to types, fields, and methods.
RemoveEmptySuperCalls	Removes calls to no-op super constructors.
RemoveEmptySuperCalls.EmptySuperCallVisitor	Removes calls to no-op super constructors.
RemoveSpecializations	Remove all method specializations before final pruning pass.
ReplaceGetClassOverrides	Prune all overrides of Object.getClass() except when the enclosing class is JavaScriptObject (to permit getClass() devirtualization in Devirtualizer to continue to work).
ResolveRebinds	Replaces any "GWT.create()" calls with a new expression for the actual result of the deferred binding decision.
ResolveRuntimeTypeReferences	Assigns and replaces JRuntimeTypeReference nodes with a type id literal.
ResolveRuntimeTypeReferences.IntTypeMapper	Sequentially creates int type ids for types.
ResolveRuntimeTypeReferences.StringTypeMapper	Predictably creates String type id literals for castable and instantiable types.
SameParameterValueOptimizer	Detects when same literal is passed as parameter value, and uses literal instead of parameter.
Simplifier	Methods that both construct and try to simplify AST nodes.
SourceGenerationVisitor	Generates Java source from our AST.
SourceInfoCorrelator	Fix up SOYC parents and add correlations.
TextOutputVisitor	A convenience base class that combines a JVisitor with a TextOutput.
ToStringGenerationVisitor	Implements a reasonable toString() for all JNodes.
TypeCoercionNormalizer	Type coercion (and operator overloading) semantics differ widely in Java and JavaScript.
TypeRefDepsChecker	A Java AST visitor that verifies that "Type A"->"Type B" references are enabled by matching "Type A Module"->"Type B Module" inherits.
TypeReferencesRecorder	Collects and Type->Type references.
TypeRemapper	A visitor that changes all JType references in the AST.
TypeTightener	The purpose of this pass is to record "type flow" information and then use the information to infer places where "tighter" (that is, more specific) types can be inferred for locals, fields, parameters, and method return types.
UnifyAst	Take independently-compiled types and merge them into a single AST.
VerifySymbolMap	Verify the validity of the symbol.
