Method Detail

getComponent

public Object getComponent(Object componentKeyOrType)

Description copied from interface: PicoContainer

Retrieve a component instance registered with a specific key or type. If a component cannot be found in this container, the parent container (if one exists) will be searched.

Specified by:

getComponent in interface PicoContainer

Parameters:

componentKeyOrType - the key or Type that the component was registered with.

Returns:

an instantiated component, or null if no component has been registered for the specified key.

getComponent

public <T> T getComponent(Class<T> componentType)

Specified by:

getComponent in interface PicoContainer

getComponents

public List getComponents()

Description copied from interface: PicoContainer

Retrieve all the registered component instances in the container, (not including those in the parent container). The components are returned in their order of instantiation, which depends on the dependency order between them.

Specified by:

getComponents in interface PicoContainer

Returns:

all the components.

getParent

public PicoContainer getParent()

Description copied from interface: PicoContainer

Retrieve the parent container of this container.

Specified by:

getParent in interface PicoContainer

Returns:

a PicoContainer instance, or null if this container does not have a parent.

getComponentAdapter

public ComponentAdapter<?> getComponentAdapter(Object componentKey)

Description copied from interface: PicoContainer

Find a component adapter associated with the specified key. If a component adapter cannot be found in this container, the parent container (if one exists) will be searched.

Specified by:

getComponentAdapter in interface PicoContainer

Parameters:

componentKey - the key that the component was registered with.

Returns:

the component adapter associated with this key, or null if no component has been registered for the specified key.

getComponentAdapter

public <T> ComponentAdapter<T> getComponentAdapter(Class<T> componentType,
                                                   ParameterName componentParameterName)

Description copied from interface: PicoContainer

Find a component adapter associated with the specified type. If a component adapter cannot be found in this container, the parent container (if one exists) will be searched.

Specified by:

getComponentAdapter in interface PicoContainer

Parameters:

componentType - the type of the component.

Returns:

the component adapter associated with this class, or null if no component has been registered for the specified key.

getComponentAdapters

public Collection<ComponentAdapter<?>> getComponentAdapters()

Description copied from interface: PicoContainer

Retrieve all the component adapters inside this container. The component adapters from the parent container are not returned.

Specified by:

getComponentAdapters in interface PicoContainer

Returns:

a collection containing all the ComponentAdapters inside this container. The collection will not be modifiable.

See Also:

a variant of this method which returns the component adapters inside this container that are associated with the specified type.

getComponentAdapters

public <T> List<ComponentAdapter<T>> getComponentAdapters(Class<T> componentType)

Description copied from interface: PicoContainer

Retrieve all component adapters inside this container that are associated with the specified type. The addComponent adapters from the parent container are not returned.

Specified by:

getComponentAdapters in interface PicoContainer

Parameters:

componentType - the type of the components.

Returns:

a collection containing all the ComponentAdapters inside this container that are associated with the specified type. Changes to this collection will not be reflected in the container itself.

getComponents

public <T> List<T> getComponents(Class<T> componentType)

Description copied from interface: PicoContainer

Returns a List of components of a certain componentType. The list is ordered by instantiation order, starting with the components instantiated first at the beginning.

Specified by:

getComponents in interface PicoContainer

Parameters:

componentType - the searched type.

Returns:

a List of components.

accept

public void accept(PicoVisitor visitor)

Description copied from interface: PicoContainer

Accepts a visitor that should visit the child containers, component adapters and component instances.

Specified by:

accept in interface PicoContainer

Parameters:

visitor - the visitor
