Constructor Detail

EModelElementItemProvider

public EModelElementItemProvider(AdapterFactory adapterFactory)
This constructs an instance from a factory and a notifier.

Method Detail

getPropertyDescriptors

public java.util.List<IItemPropertyDescriptor> getPropertyDescriptors(java.lang.Object object)
This returns the property descriptors for the adapted class.

Specified by:
getPropertyDescriptors in interface IItemPropertySource
Overrides:
getPropertyDescriptors in class EObjectItemProvider

getChildrenFeatures

public java.util.Collection<? extends EStructuralFeature> getChildrenFeatures(java.lang.Object object)
This specifies how to implement ItemProviderAdapter.getChildren(java.lang.Object) and is used to deduce an appropriate feature for an AddCommand, RemoveCommand or MoveCommand in ItemProviderAdapter.createCommand(java.lang.Object, org.eclipse.emf.edit.domain.EditingDomain, java.lang.Class, org.eclipse.emf.edit.command.CommandParameter).

Overrides:
getChildrenFeatures in class ItemProviderAdapter

getChildFeature

protected EStructuralFeature getChildFeature(java.lang.Object object,
                                             java.lang.Object child)

Overrides:
getChildFeature in class ItemProviderAdapter

getText

public java.lang.String getText(java.lang.Object object)
This returns the label text for the adapted class.

Specified by:
getText in interface IItemLabelProvider
Overrides:
getText in class EObjectItemProvider

notifyChanged

public void notifyChanged(Notification notification)
This handles model notifications by calling ItemProviderAdapter.updateChildren(org.eclipse.emf.common.notify.Notification) to update any cached children and by creating a viewer notification, which it passes to ItemProviderAdapter.fireNotifyChanged(org.eclipse.emf.common.notify.Notification).

Specified by:
notifyChanged in interface Adapter
Overrides:
notifyChanged in class EObjectItemProvider
Parameters:
notification - a description of the change.

collectNewChildDescriptors

protected void collectNewChildDescriptors(java.util.Collection<java.lang.Object> newChildDescriptors,
                                          java.lang.Object object)
This adds CommandParameters describing the children that can be created under this object.

Overrides:
collectNewChildDescriptors in class EObjectItemProvider

stripToNull

public java.lang.String stripToNull(java.lang.String value)
Strips whitespace and converts the empty string to null.

Parameters:
value - Any string or null.
Returns:
the trimmed value or null if it's an empty string.
