Constructor Detail

MappingHelperItemProvider

public MappingHelperItemProvider(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 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

getChildren

public java.util.Collection<?> getChildren(java.lang.Object object)
Description copied from class: ItemProviderAdapter
This implements ITreeItemContentProvider.getChildren. If children are already cached in a ItemProviderAdapter.ChildrenStore, they are returned. Otherwise, children are collected from the features returned by getChildrenFeatures. The collected children may or may not be cached, depending on the result of createChildrenStore; by default, no store is returned if getChildrenFeatures returns only containment references. All children are optionally wrapped before being cached and returned. Subclasses may override createWrapper to specify when and with what to wrap children.

Specified by:
getChildren in interface IEditingDomainItemProvider
Specified by:
getChildren in interface ITreeItemContentProvider
Overrides:
getChildren in class ItemProviderAdapter

hasChildren

public boolean hasChildren(java.lang.Object object)
Description copied from class: ItemProviderAdapter
This implements ITreeItemContentProvider.hasChildren by simply testing whether getChildren returns any children. This implementation will always be right, however, for efficiency you may want to override it to return false or use the optimized approach offered by ItemProviderAdapter.hasChildren(Object, boolean) (i.e. by passing true as the second argument).

Specified by:
hasChildren in interface ITreeItemContentProvider
Overrides:
hasChildren in class ItemProviderAdapter
See Also:
ItemProviderAdapter.hasChildren(Object, boolean)

getParent

public java.lang.Object getParent(java.lang.Object object)
This returns the mapper of the MappingHelper.

Specified by:
getParent in interface IEditingDomainItemProvider
Specified by:
getParent in interface ITreeItemContentProvider
Overrides:
getParent in class ItemProviderAdapter

getImage

public java.lang.Object getImage(java.lang.Object object)
This returns MappingHelper.gif.

Specified by:
getImage in interface IItemLabelProvider
Overrides:
getImage in class ItemProviderAdapter

getText

public java.lang.String getText(java.lang.Object object)
Description copied from class: ItemProviderAdapter
This implements IItemLabelProvider.getText by simply calling toString on the argument. This will often be correct as is.

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

notifyChanged

public void notifyChanged(Notification msg)
This handles notification by delegating to fireNotifyChanged.

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

getResourceLocator

public ResourceLocator getResourceLocator()
Return the resource locator for this item provider's resources.

Overrides:
getResourceLocator in class ItemProviderAdapter
