Description

Interface Summary

ClassInspector	Service that provides a common interface to other lower level reflection services to provide a common set of functionality for reflection when using a 1.4 or >= 1.5 jre.
DeferredScript	A wrapper around IScriptSource that will obtain an IScript instance as needed.
EnhancedClassValidator
EnhancementOperation	A process object representing enhancements to a component class.
EnhancementWorker	A worker that is employed by the ComponentConstructorFactory to perform some enhancement.
InjectEnhancementWorker	A kind of enhancement worker dedicated to injection, based on the <inject> element of the specification.
MethodSignature	A representation of a Method, identifying the name, return type, parameter types and exception types.

Class Summary

AbstractFab	Common code for ClassFabImpl and InterfaceFabImpl.
AbstractPropertyWorker	No, this class isn't abstract ...
AutowireWorker	An enhancement worker which automatically injects HiveMind services into pages/components if exactly one service point exists which is compatible with the read-only property's type.
AutowireWorkerFactory	Constructs AutowireWorkers.
ClassFabImpl	Implementation replacement for hivemind ClassFab utiltity to get around some javassist incompatibilties found with the latest 3.4 version of javassist.
ClassFactoryImpl	Implementation of the hivemind core ClassFactory service to get around some incompatibilities the current 1.1.1 implementation of hivemind has with the latest (3.4) version of javassist.
ClassInspectorImpl	Implemenation of ClassInspector that is compatible with 1.4 jres.
ClientIdPropertyWorker	Enhances the IComponent.getClientId() property.
ComponentConstructorImpl
CtClassSource	Wrapper around Javassist's ClassPool and our own ClassFactoryClassLoader that manages the creation of new instance of CtClass and converts finished CtClass's into instantiable Classes.
DeferredScriptImpl
DispatchToInjectWorker	Iterates over the InjectSpecifications and locates and delegates to a InjectEnhancementWorker for each one.
EnhancedClassValidatorImpl	Validates that an enhanced class is correct; checks that all inherited abstract methods are, in fact, implemented in the class.
EnhancementOperationImpl	Implementation of EnhancementOperationthat knows how to collect class changes from enhancements.
EnhanceUtils	Convienience methods needed by various parts of the enhancement subsystem.
GenericsClassInspectorImpl	Implementation of ClassInspector that can properly handle jre 1.5 generic types.
GenericsMethodSignatureImpl	Implementation of MethodSignature that supports jdk 1.5 generic typing support.
HiveMindClassPool	Used to ensure that ClassPool.appendClassPath(javassist.ClassPath) is invoked with a synchronized lock.
InitialValueBindingCreator	Encapsulates information needed to construct an initial value binding for a specified property (with an initial value).
InjectAssetWorker	Injects assets as component properties.
InjectBeanWorker	Injects a property that will dynamically access a managed bean.
InjectComponentWorker	Injects components for which the property attribute of the <component> element was specified.
InjectEventInvokerWorker	Injects the component's event invoker as the eventInvokerproperty.
InjectListenerRegistrationWorker	Checks to see if the component implements a specific interface, and adds code to the component's finishLoad() method to register (with the page) for such notifications.
InjectMessagesWorker	Injects the read-only messagesproperty into all components.
InjectMetaWorker	Injects meta data obtained via ComponentPropertySource (meaning that meta-data is searched for in the component's specification, then it's namespace (library or application specification), then the global application properties.
InjectObjectWorker	Implementation for injection type "object" (the default).
InjectPageWorker	Injects code to access a named page within the application.
InjectRenderWorker	Injects the component's render worker chain as the renderWorkerproperty.
InjectScriptWorker	Injects IScript instances directly into pages or components.
InjectSpecificationWorker	Injects the component's specification as the specificationproperty.
InjectStateFlagWorker	Injects a boolean property that indicates if a particular application state object already exists.
InjectStateWorker	Worker for injecting application state objects as properties of the component.
InterfaceFabImpl
JavaClassMapping
MethodFabImpl	Implementation of hivemind MethodFab utiltity.
MethodSignatureImpl	JDK 1.4 based version of MethodSignature.
ParameterPropertyWorker	Responsible for creating properties for connected parameters.
SpecifiedPropertyWorker	Responsible for adding properties to a class corresponding to specified properties in the component's specification - which may come from .jwc / .page specifications or annotated abstract methods.
