getComponentIds

public Set<String> getComponentIds()

Description copied from interface: BlueprintContainer

Returns the set of component ids managed by this Blueprint Container.

Specified by:

getComponentIds in interface BlueprintContainer

Returns:

An immutable Set of Strings, containing the ids of all of the components managed within this Blueprint Container.

getComponentInstance

public Object getComponentInstance(String id)
                            throws NoSuchComponentException

Description copied from interface: BlueprintContainer

Return the component instance for the specified component id. If the component's manager has not yet been activated, calling this operation will atomically activate it. If the component has singleton scope, the activation will cause the component instance to be created and initialized. If the component has prototype scope, then each call to this method will return a new component instance.

Specified by:

getComponentInstance in interface BlueprintContainer

Parameters:

id - The component id for the requested component instance.

Returns:

A component instance for the component with the specified component id.

Throws:

NoSuchComponentException - If no component with the specified component id is managed by this Blueprint Container.

getComponentMetadata

public ComponentMetadata getComponentMetadata(String id)

Description copied from interface: BlueprintContainer

Return the Component Metadata object for the component with the specified component id.

Specified by:

getComponentMetadata in interface BlueprintContainer

Parameters:

id - The component id for the requested Component Metadata.

Returns:

The Component Metadata object for the component with the specified component id.

getMetadata

public <T extends ComponentMetadata> Collection<T> getMetadata(Class<T> clazz)

Description copied from interface: BlueprintContainer

Return all ComponentMetadata objects of the specified Component Metadata type. The supported Component Metadata types are ComponentMetadata (which returns the Component Metadata for all defined manager types), BeanMetadata , ServiceReferenceMetadata (which returns both ReferenceMetadata and ReferenceListMetadata objects), and ServiceMetadata. The collection will include all Component Metadata objects of the requested type, including components that are declared inline.

Specified by:

getMetadata in interface BlueprintContainer

Parameters:

clazz - The super type or type of the requested Component Metadata objects.

Returns:

An immutable collection of Component Metadata objects of the specified type.

getConverter

public Converter getConverter()

Specified by:

getConverter in interface ExtendedBlueprintContainer

getComponentDefinitionRegistry

public ComponentDefinitionRegistryImpl getComponentDefinitionRegistry()

Specified by:

getComponentDefinitionRegistry in interface ExtendedBlueprintContainer

getBundleContext

public org.osgi.framework.BundleContext getBundleContext()

Specified by:

getBundleContext in interface ExtendedBlueprintContainer

destroy

public void destroy()

quiesce

protected void quiesce()

namespaceHandlerRegistered

public void namespaceHandlerRegistered(URI uri)

Description copied from interface: NamespaceHandlerRegistry.Listener

Called when a NamespaceHandler has been registered for the specified URI.

Specified by:

namespaceHandlerRegistered in interface NamespaceHandlerRegistry.Listener

Parameters:

uri - the URI of the newly registered namespace handler

namespaceHandlerUnregistered

public void namespaceHandlerUnregistered(URI uri)

Description copied from interface: NamespaceHandlerRegistry.Listener
