Fields Summary
CategoriesMap	categories The categories.

Constructors Summary

public ServiceRegistry(Iterator categoriesIterator) Instantiates a new ServiceRegistry with the specified categories. param categoriesIterator an Iterator of Class objects for defining of categories. if (null == categoriesIterator) { throw new IllegalArgumentException("categories iterator should not be NULL"); } while (categoriesIterator.hasNext()) { Class<?> c = categoriesIterator.next(); categories.addCategory(c); }

Methods Summary
public boolean	contains(java.lang.Object provider) Checks whether the specified provider has been already registered. param provider the provider to be checked. return true, if the specified provider has been already registered, false otherwise. throw new UnsupportedOperationException("Not supported yet");
public void	deregisterAll(java.lang.Class category) Deregisters all providers from the specified category. param category the specified category. throw new UnsupportedOperationException("Not supported yet");
public void	deregisterAll() Deregister all providers from all categories. throw new UnsupportedOperationException("Not supported yet");
public boolean	deregisterServiceProvider(T provider, java.lang.Class category) Deregisters the specifies service provider from the specified category. param provider the service provider to be deregistered. param category the specified category. return true, if the provider was already registered in the specified category, false otherwise. throw new UnsupportedOperationException("Not supported yet");
public void	deregisterServiceProvider(java.lang.Object provider) Deregisters the specified service provider from all categories. param provider the specified service provider. throw new UnsupportedOperationException("Not supported yet");
public void	finalize() Finalizes this object. throws Throwable if an error occurs during finalization. // TODO uncomment when deregisterAll is implemented // deregisterAll();
public java.util.Iterator	getCategories() Gets an iterator of Class objects representing the current categories. return the Iterator of Class objects. return categories.list();
public T	getServiceProviderByClass(java.lang.Class providerClass) Gets the registered service provider object that has the specified class type. param providerClass the specified provider class. return the service provider object. throw new UnsupportedOperationException("Not supported yet");
public java.util.Iterator	getServiceProviders(java.lang.Class category, boolean useOrdering) Gets an Iterator of all registered service providers in the specified category. The useOrdering parameter indicates whether the iterator will return all of the server provider objects in a set order. param category the specified category. param useOrdering the flag indicating that providers are ordered in the returned Iterator. return the Iterator of service providers. return (Iterator<T>)categories.getProviders(category, useOrdering);
public java.util.Iterator	getServiceProviders(java.lang.Class category, javax.imageio.spi.ServiceRegistry$Filter filter, boolean useOrdering) Gets an Iterator of registered service providers in the specified category which satisfy the specified Filter. The useOrdering parameter indicates whether the iterator will return all of the server provider objects in a set order. param category the specified category. param filter the specified filter. param useOrdering the flag indicating that providers are ordered in the returned Iterator. return the iterator of registered service providers. return new FilteredIterator<T>(filter, (Iterator<T>)categories.getProviders(category, useOrdering));
public static java.util.Iterator	lookupProviders(java.lang.Class providerClass, java.lang.ClassLoader loader) Looks up and instantiates the available providers of this service using the specified class loader. param providerClass the Class object of the provider to be looked up. param loader the class loader to be used. return the iterator of providers objects for this service. throw new UnsupportedOperationException("Not supported yet");
public static java.util.Iterator	lookupProviders(java.lang.Class providerClass) Looks up and instantiates the available providers of this service using the context class loader. param providerClass the Class object of the provider to be looked up. return the iterator of providers objects for this service. return lookupProviders(providerClass, Thread.currentThread().getContextClassLoader());
public boolean	registerServiceProvider(T provider, java.lang.Class category) Registers the specified service provider object in the specified categories. param provider the specified provider to be registered. param category the category. return true, if no provider of the same class is registered in this category, false otherwise. return categories.addProvider(provider, category);
public void	registerServiceProvider(java.lang.Object provider) Registers the specified service provider object in all categories. param provider the service provider. categories.addProvider(provider, null);
public void	registerServiceProviders(java.util.Iterator providers) Registers a list of service providers. param providers the list of service providers. for (Iterator<?> iterator = providers; iterator.hasNext();) { categories.addProvider(iterator.next(), null); }
public boolean	setOrdering(java.lang.Class category, T firstProvider, T secondProvider) Sets an ordering between two service provider objects within the specified category. param category the specified category. param firstProvider the first provider. param secondProvider the second provider. return true, if a previously unset order was set. throw new UnsupportedOperationException("Not supported yet");
public boolean	unsetOrdering(java.lang.Class category, T firstProvider, T secondProvider) Unsets an ordering between two service provider objects within the specified category. param category the specified category. param firstProvider the first provider. param secondProvider the second provider. return true, if a previously unset order was removed. throw new UnsupportedOperationException("Not supported yet");
