Constructor Details

ExtensionBean

public ExtensionBean()

Create a new empty extension bean. Use the setter methods to set the properties before registering the extension with Registry.registerExtension(Extension, ClassLoader).

ExtensionBean

public ExtensionBean(String id,
String extensionPoint,
float position,
About about,
ActionFactory<? extends A> actionFactory,
RendererFactory<? super A> rendererFactory)

Create a new fully initialised extension bean. See the Extension interface for a description of the parameters.

Method Details

toString

public String toString()

Overrides:

toString in class Object

getId

public String getId()

Description copied from interface: Extension

Get the ID of the extension.

Specified by:

getId in interface Extension<A extends Action>

Returns:

A non-null unique identifier value

setId

public void setId(String id)

getExtends

public String getExtends()

Description copied from interface: Extension

Get the ID of the extension point this extension is extending.

Specified by:

getExtends in interface Extension<A extends Action>

Returns:

A non-null identifier value

setExtends

public void setExtends(String extensionPoint)

getIndex

public float getIndex()

Description copied from interface: Extension

The extensions in an extension point are by default ordered by their index value. Extensions with a low value are ordered before extensions with a high value. The ordering may be overridden by providing an external ExtensionsFilter implementation.

Specified by:

getIndex in interface Extension<A extends Action>

Returns:

The index value

setIndex

public void setIndex(float index)

getActionFactory

public ActionFactory<? extends A> getActionFactory()

Description copied from interface: Extension

Get the factory class for creating actions. The factory must create objects of the same class or a subclass as the ExtensionPoint.getActionClass() method of the extended extension point returns.

Specified by:

getActionFactory in interface Extension<A extends Action>

Returns:

An action factory (required)

setActionFactory

public void setActionFactory(ActionFactory<? extends A> actionFactory)

getRendererFactory

public RendererFactory<? super A> getRendererFactory()

Description copied from interface: Extension

Get an optional factory class for creating renderers for the actions. This factory will only be used if the extension point allows it.

Specified by:

getRendererFactory in interface Extension<A extends Action>

Returns:

A renderer factory or null

See Also:

ExtensionPoint.allowRendererOverride()

setRendererFactory

public void setRendererFactory(RendererFactory<? super A> rendererFactory)

getAbout

public About getAbout()

Description copied from interface: Extension

Get information about the extensions. This is optional, but we recommend that at least some documentation and contact information is given.

Specified by:

getAbout in interface Extension<A extends Action>

Returns:

Optional information about the extension

setAbout

public void setAbout(About about)
