Interface IPipelinedTreeContentProvider2
- All Superinterfaces:
- ICommonContentProvider, IContentProvider, IMementoAware, IPipelinedTreeContentProvider, IStructuredContentProvider, ITreeContentProvider
public interface IPipelinedTreeContentProvider2
- extends IPipelinedTreeContentProvider
A pipelined content provider allows an extension to reshape the contributions
of an upstream content extension.
An "upstream" extension is either:
- the extension overridden by this extension using the
org.eclipse.ui.navigatorContent/navigatorContent/override element, or
- another extension that overrides the same extension this extension
overrides, but with higher priority than this extension.
Overridden extensions form a tree where the nodes of the tree represent the
content extensions, children represent overriding extensions, and the
children are sorted by priority. Pipeline contributions traverse the tree,
allowing children to override the contributions of their parent, giving
precedence to the children of highest priority.
ITreeContentProvider
is respected by the Common Navigator.
Note: this should be used instead of IPipelinedTreeContentProvider
so
that the hasChildren indication reflects the actual pipelined children that
will be presented.
