Class FlexTarget

java.lang.Object

org.apache.flex.compiler.internal.targets.FlexTarget

public abstract class FlexTarget
extends Object

Delegate class used by flex specific targets to generate flex specific code. If we were writing this compiler in C++ this would be a mix-in class.

Field Detail

flexProject

protected final FlexProject flexProject

accessibleClassNames

protected final HashSet<String> accessibleClassNames

Set of classes referenced from accessibility meta-data.

For Example:

[AccessibilityClass(implementation="mx.accessibility.ButtonAccImpl")]

This set is accumulated as we discover direct dependencies, which is not as maintainable as I would like.

Method Detail

codegenCallInContextMethod

protected final void codegenCallInContextMethod(ClassGeneratorHelper classGen,
                              boolean isOverride)

Codegen IFlexModuleFactory.callInContext(); public final override function callInContext(fn:Function, thisArg:Object, argArray:Array, returns:Boolean=true) : * { var ret : * = fn.apply(thisArg, argArray); if (returns) return ret; return; }

Parameters:

classGen -

isOverride - true if the generated method overrides a base class method, false otherwise.

codegenCreateMethod

protected final void codegenCreateMethod(ClassGeneratorHelper classGen,
                       Name mainApplicationName)

Codegen IFlexModuleFactory.create() override public function create(... params):Object { var mainClass : Class; if (params.length <= 0) { mainClass = getlex MainApplicationClass } else if (params[0] is String) { mainClass = getDefinitionByName(params[0]) } else return super.create.apply(this, params); if (!mainClass) return null; var instance:Object = new mainClass(); if (instance is IFlexModule) (IFlexModule(instance)).moduleFactory = this; return instance; }

Parameters:

classGen -

mainApplicationName - Name that will refer to the main application class at runtme. May not be null but a library.swf for a SWC may pass in a Name that resolves to "Object" at runtime.

codegenInfoMethod

protected final void codegenInfoMethod(ClassGeneratorHelper classGen,
                     Integer compatibilityVersion,
                     String mainClassQName,
                     IResolvedQualifiersReference preloaderReference,
                     IResolvedQualifiersReference runtimeDPIProviderReference,
                     org.apache.flex.compiler.internal.targets.FlexSplashScreenImage splashScreen,
                     IASNode rootNode,
                     ITargetAttributes targetAttributes,
                     Collection<String> compiledLocales,
                     org.apache.flex.compiler.internal.targets.FlexFrame1Info frame1Info,
                     Set<String> accessibilityClassNames,
                     String flexInitClassName,
                     String stylesClassName,
                     List<String> rsls,
                     org.apache.flex.compiler.internal.targets.FlexRSLInfo rslInfo,
                     Collection<ICompilerProblem> problemCollection,
                     boolean isAppFlexInfo)
                                throws InterruptedException

Codegen the IFlexModuleFactory.info() method. public override final function info() : Object { if (!_info) { _info = { currentDomain : ApplicationDomain.currentDomain . . . } } }

Parameters:

classGen - used to create the function

compatibilityVersion - compatibility version set in the compiler option. May be null if not configured.

mainClassQName - qName of the main class of the application. May be null of library swfs.

preloaderReference - reference to the configured preloader class. May be null for library swfs.

runtimeDPIProviderReference - configured runtimeDPIProvider. May be null for library swfs.

splashScreen - reference to the configured splash screen.

rootNode - root node of the application. May be null for library swfs.

compiledLocales - the locales supported by this application. May be null for library swfs.

rsls - legacy RSLs. May be null for library swfs.

problemCollection - problems found when generating the info method are added to the collection.

Throws:

InterruptedException

getAccessibilityDependencies

public Target.DirectDependencies getAccessibilityDependencies(ICompilationUnit compilationUnit)
                                                       throws InterruptedException

Find the accessible compilation units on a set of compilation units. The accessible compilation units are gathered from the [AccessiblityClass] meta-data on a class.

Unfortunately this method has a side effect, it updates the set of accessibility classes.

Parameters:

compilationUnit - A compilation unit.

Returns:

A Target.DirectDependencies object with the set of compilation units representing the new compilation units needed for accessibility. If no accessible compilation units are found or accessibility is not enabled on the target, then the returned Target.DirectDependencies object will contain an empty set.

Throws:

InterruptedException

addProductInfoToSWF

public void addProductInfoToSWF(ISWF swf)

Update the SWF model by adding a ProductInfoTag.

Parameters:

swf - the swf model to update.
