Method Summary

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
protected EStructuralFeature	getChildFeature(java.lang.Object object, java.lang.Object child)
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)
java.util.List<IItemPropertyDescriptor>	getPropertyDescriptors(java.lang.Object object) This returns the property descriptors for the adapted class

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 ItemProviderAdapter

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 ItemProviderAdapter

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 AdapterImpl

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 ItemProviderAdapter

getResourceLocator

public ResourceLocator getResourceLocator()

Return the resource locator for this item provider's resources.

Overrides:

getResourceLocator in class ItemProviderAdapter

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.
