Interface INavigatorContentExtension

All Superinterfaces:

IAdaptable

public interface INavigatorContentExtension
extends IAdaptable

The content extension represents the components of a navigatorContent extension. These handles are managed by a content service INavigatorContentService. An extension is formed from the INavigatorContentDescriptor.

There is a one-to-many correspondence between the INavigatorContentDescriptor and INavigatorContentExtension. An instance of the INavigatorContentExtension is created for each INavigatorContentDescriptor used by a INavigatorContentService.

Since:

3.2

Restriction:

This interface is not intended to be implemented by clients.

Restriction:

This interface is not intended to be extended by clients.

Method Summary

Modifier and Type	Method	Description
ITreeContentProvider	getContentProvider()	Clients may choose to implement ICommonContentProvider, but are only required to supply an implementation of ITreeContentProvider.
INavigatorContentDescriptor	getDescriptor()	There is one descriptor for all instances of a INavigatorContentExtension.
String	getId()
ICommonLabelProvider	getLabelProvider()	The real underlying implementation may only support the ILabelProvider interface, but a simple delegate is used when this is the case to ensure that clients may anticipate an ICommonLabelProvider interface.
IExtensionStateModel	getStateModel()
boolean	isLoaded()

Method Details

getId

String getId()

getDescriptor

INavigatorContentDescriptor getDescriptor()

There is one descriptor for all instances of a INavigatorContentExtension.

Returns:

A handle to the descriptor used to manage this extension.

getContentProvider

ITreeContentProvider getContentProvider()

Clients may choose to implement ICommonContentProvider, but are only required to supply an implementation of ITreeContentProvider.

Returns:

The content provider defined by the navigatorContent extension.

getLabelProvider

ICommonLabelProvider getLabelProvider()

The real underlying implementation may only support the ILabelProvider interface, but a simple delegate is used when this is the case to ensure that clients may anticipate an ICommonLabelProvider interface.

Since 3.4, the returned label provider may also implement DelegatingStyledCellLabelProvider.IStyledLabelProvider to provide styled text labels. Note that the empty styled string signals that the label provider does not wish to render the label.

Returns:

The content provider defined by the navigatorContent extension.

• ICommonLabelProvider
• ILabelProvider

isLoaded

boolean isLoaded()

Returns:

True if any class has been instantiated by this extension.

getStateModel

IExtensionStateModel getStateModel()

The state model associated with this content extension.
