UiModelTreeContentProvider

public class UiModelTreeContentProvider extends Object implements org.eclipse.jface.viewers.ITreeContentProvider
UiModelTreeContentProvider is a trivial implementation of {@link ITreeContentProvider} where elements are expected to be instances of {@link UiElementNode}.

Fields Summary
private com.android.ide.eclipse.editors.descriptors.ElementDescriptor[]
mDescriptorFilters
The descriptor of the elements to be displayed as root in this tree view. All elements of the same type in the root will be displayed.
private final com.android.ide.eclipse.editors.uimodel.UiElementNode
mUiRootNode
The uiRootNode of the model.
