## org.eclipse.gemini.blueprint.blueprint.container
Class SpringBlueprintContainer

    java.lang.Object
      org.eclipse.gemini.blueprint.blueprint.container.SpringBlueprintContainer

All Implemented Interfaces:
  BlueprintContainer

    public class SpringBlueprintContainer

extends Object
implements BlueprintContainer

Default `BlueprintContainer` implementation. Wraps Spring's `ConfigurableListableBeanFactory` in the BlueprintContainer interface. Note: This class does not fully implements the Blueprint contract: for example it does not fire any of the Blueprint events nor performs exception handling - these concerns are left to the Blueprint extender.

Method Detail

### getComponentInstance

    public Object getComponentInstance(String name)
                                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:
    `name` - 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 name)
                                           throws NoSuchComponentException

  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:
    `name` - The component id for the requested Component Metadata.
  Returns:
    The Component Metadata object for the component with the specified component id.
  Throws:
    `NoSuchComponentException` - If no component with the specified component id is managed by this Blueprint Container.

### 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.

### getMetadata

    public Collection<?> getMetadata(Class type)

  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:
    `type` - The super type or type of the requested Component Metadata objects.
  Returns:
    An immutable collection of Component Metadata objects of the specified type.
