Constructor Summary

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

Method Summary

Collection	getChildren(Object object) This does the same thing as EditingDomain.getChildren, i.e., it imposes a hierarchical relation on a domain's model objects.
Collection	getChildrenFeatures(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)
Object	getImage(Object object) This returns MappingHelper.gif.
Object	getParent(Object object) This returns the mapper of the MappingHelper.
List	getPropertyDescriptors(Object object) This returns the property descriptors for the adapted class.
ResourceLocator	getResourceLocator() Return the resource locator for this item provider's resources
String	getText(Object object) This does the same thing as ILabelProvider.getlText, it fetches the label text specific to this object instance.
boolean	hasChildren(Object object) This does the same thing as ITreeContentProvider.hasChildren.
void	notifyChanged(Notification msg) This handles notification by delegating to fireNotifyChanged.

Constructor Detail

MappingHelperItemProvider

public MappingHelperItemProvider(AdapterFactory adapterFactory)

This constructs an instance from a factory and a notifier.

Method Detail

getPropertyDescriptors

public List getPropertyDescriptors(Object object)

This returns the property descriptors for the adapted class.

Specified by:

getPropertyDescriptors in interface IItemPropertySource

Overrides:

getPropertyDescriptors in class ItemProviderAdapter

getChildrenFeatures

public Collection getChildrenFeatures(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

getChildren

public Collection getChildren(Object object)

Description copied from interface: IEditingDomainItemProvider

This does the same thing as EditingDomain.getChildren, i.e., it imposes a hierarchical relation on a domain's model objects.

Specified by:

getChildren in interface IEditingDomainItemProvider

Overrides:

getChildren in class ItemProviderAdapter

hasChildren

public boolean hasChildren(Object object)

Specified by:

getImage in interface IItemLabelProvider

Overrides:

getImage in class ItemProviderAdapter

getText

public String getText(Object object)

Description copied from interface: IItemLabelProvider

This does the same thing as ILabelProvider.getlText, it fetches the label text specific to this object instance.

Specified by:

getText in interface IItemLabelProvider

Overrides:

getText in class ItemProviderAdapter

notifyChanged

public void notifyChanged(Notification msg)

This handles notification by delegating to fireNotifyChanged.
