features

protected Map<Class<Object>,Object> features

The feature instances of this component, stored by the feature type.

id

protected ComponentIdentifier id

The id.

access

protected IExternalAccess access

The external access.

accessfactory

protected static Function<Component,IExternalAccess> accessfactory

The external access supplier.

Constructor Details

Component

public Component()

Create a new component and instantiate all features (except lazy features). Uses an auto-generated componment identifier.

Component

public Component(ComponentIdentifier id)

Create a new component and instantiate all features (except lazy features).

Parameters:

id - The id to use or null for an auto-generated id.

Throws:

IllegalArgumentException - when the id already exists.

Method Details

getId

public ComponentIdentifier getId()

Get the id.

Specified by:

getId in interface IComponent

Returns:

The id.

getFeatures

public Collection<Object> getFeatures()

Get the internal set of currently instantiated features. Does not include lazy, which have not yet been accessed.

hasFeature

public boolean hasFeature(Class<?> type)

Check if has a feature.

Returns:

True, if it has the feature.

getFeature

public <T> T getFeature(Class<T> type)

Get the feature instance for the given type. Instantiates lazy features if needed.

Specified by:

getFeature in interface IComponent

terminate

public void terminate()

Terminate the component.

Specified by:

terminate in interface IComponent

getPojo

public Object getPojo()

Get the pojo.

Specified by:

getPojo in interface IComponent

Returns:

The pojo.

putFeature

protected void putFeature(Class<Object> type,
 Object feature)

getExternalAccess

public IExternalAccess getExternalAccess()

Get the external access.

Specified by:

getExternalAccess in interface IComponent

Returns:

The external access.

handleException

public void handleException(Exception exception)

getExternalAccess

public IExternalAccess getExternalAccess(ComponentIdentifier cid)

Get the external access.

Specified by:

getExternalAccess in interface IComponent

Parameters:

cid - The component id.

Returns:

The external access.

setExternalAccessFactory

public static void setExternalAccessFactory(Function<Component,IExternalAccess> factory)

Set the external access factory.

Parameters:

factory - The factory.
