ApplicationRegistry

• java.lang.Object

Fields Summary
protected Hashtable	appID2ClassLoader application id vs class loader
protected Hashtable	moduleID2ClassLoader stand alone module id vs class loader
protected Hashtable	classLoader2Application ClassLoader vs Application Objects
protected Hashtable	descriptor2Container EJBDescriptor vs Container
private HashSet	uniqueIds holds unique ids of ejb containers for each deployed applications
private static ApplicationRegistry	_instance the singleton instance

Constructors Summary
private ApplicationRegistry() Initializes the registry. this.appID2ClassLoader = new Hashtable(); this.moduleID2ClassLoader = new Hashtable(); this.descriptor2Container = new Hashtable(); this.classLoader2Application = new Hashtable(); this.uniqueIds = new HashSet();

Methods Summary
void	addAppId2ClassLoader(java.lang.String appID, java.lang.ClassLoader classLoader) Stores class loader against the given registration name for application. param appID registration name of the application param classLoader class loader associated with this application appID2ClassLoader.put(appID, classLoader);
void	addClassLoader2Application(java.lang.ClassLoader classLoader, com.sun.enterprise.deployment.Application app) Stores the deployment descriptor hierarchy against the class loader. param classLoader class loader used in an app param app deployment descriptor hierarchy classLoader2Application.put(classLoader, app);
void	addDescriptor2Container(com.sun.enterprise.deployment.EjbDescriptor desc, com.sun.ejb.Container container) Stores the given deployment descriptor and ejb container in a table. param desc deployment descriptor of an ejb param container ejb container descriptor2Container.put(desc, container);
void	addModuleId2ClassLoader(java.lang.String moduleID, java.lang.ClassLoader classLoader) Stores class loader against the given registration name for stand alone module. We are keeping separate table because of possible name space collision. param moduleID registration name of stand alone module param classLoader class loader associated with this module moduleID2ClassLoader.put(moduleID, classLoader);
java.util.Collection	getAllEjbContainers() Returns all the ejb containers available in this registry. This includes J2EE applications and stand alone ejb modules. return a collection of ejb containers Collection containers = null; if (this.descriptor2Container != null) { containers = this.descriptor2Container.values(); } return containers;
public com.sun.enterprise.deployment.Application	getApplication(java.lang.ClassLoader loader) Return the Application for the given classloader. It is assumed that there is a 1-to-1 mapping from app to loader. This is called at runtime from the Persistence Manager. param loader class loader return deployment descriptor hierarchy for the given class loader return (Application) classLoader2Application.get(loader);
public java.lang.ClassLoader	getClassLoaderForApplication(java.lang.String appID) Get the class loader of a given application. Used in ServletDeployerImpl param appID registration name of an application return the class loader for the given registration name return (ClassLoader) appID2ClassLoader.get(appID);
public java.lang.ClassLoader	getClassLoaderForModule(java.lang.String moduleID) Get the class loader of the given stand alone module. param moduleID registration name of a stand alone module return the class loader for the given stand alone module registration name return (ClassLoader) moduleID2ClassLoader.get(moduleID);
public com.sun.ejb.Container	getContainer(com.sun.enterprise.deployment.EjbDescriptor desc) Return the Container for the given EjbDescriptor. This is called at runtime from the Persistence Manager. param desc ejb deployment descriptor return the ejb container for the given descriptor obj return (Container) descriptor2Container.get(desc);
public static com.sun.enterprise.server.ApplicationRegistry	getInstance() Returns the singleton instance. return the singleton instance _instance = new ApplicationRegistry(); return _instance;
boolean	isUnique(long uniqueId) Returns true if the given id is not already present in this registry. It adds the specified unique id to the registry if not already present. This is used to detect collision between two ejb bean containers. param uniqueId unique id of an ejb bean container return true if the given id is not already present in this registry return this.uniqueIds.add( new Long(uniqueId) );
java.lang.ClassLoader	removeAppId2ClassLoader(java.lang.String appID) Removes the class loader associated with the given registration name. param appID registration name of an app return the removed class loader return (ClassLoader) appID2ClassLoader.remove(appID);
com.sun.enterprise.deployment.Application	removeClassLoader2Application(java.lang.ClassLoader cl) Removes the deployment descriptor hierarchy associated with the given class loader. param cl class loader used in an app return the removed deployment descriptor hierarchy return (Application) classLoader2Application.remove(cl);
com.sun.ejb.Container	removeDescriptor2Container(com.sun.enterprise.deployment.EjbDescriptor desc) Removes the ejb container associated with the given deployment descriptor. param desc ejb deployment descriptor return the removed ejb container return (Container) descriptor2Container.remove(desc);
java.lang.ClassLoader	removeModuleId2ClassLoader(java.lang.String moduleID) Removes the class loader associated with the given stand alone module registration name. We are keeping separate table because of possible name space collision. param moduleID registration name of stand alone module return the removed class loader return (ClassLoader) moduleID2ClassLoader.remove(moduleID);
boolean	removeUniqueId(long uniqueId) Removes the given id from this registry. param uniqueId unique if of an ejb bean container return true if the registry contained the specified id return this.uniqueIds.remove( new Long(uniqueId) );
