Constructor Summary

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

Method Summary

protected Command	createAddCommand(EditingDomain domain, EObject owner, EStructuralFeature feature, Collection collection, int index) This creates a primitive AddCommand.
Command	createCommand(Object object, EditingDomain editingDomain, Class commandClass, CommandParameter commandParameter) This does the same thing as EditingDomain.createCommand, i.e., it creates commands for a domain's model objects.
protected Command	createMoveCommand(EditingDomain domain, EObject owner, EStructuralFeature feature, EObject value, int index) This creates a primitive MoveCommand.
protected Command	createNameMatchMappingCommand(MappingDomain domain, Mapping mapping) This creates a primitive NameMatchMappingCommand.
protected Command	createRemoveCommand(EditingDomain domain, EObject owner, EStructuralFeature feature, Collection collection) This creates a primitive RemoveCommand.
protected Command	createSetCommand(EditingDomain domain, EObject owner, EStructuralFeature feature, Object value) This creates a primitive SetCommand.
protected Command	createTypeMatchMappingCommand(MappingDomain domain, Mapping mapping) This creates a primitive TypeMatchMappingCommand.
static Iterator	createValueIterator(Object object)
void	dispose() This will remove this adapter from all its the targets and dispose any remainging children wrappers in the children store.
protected Command	factorAddCommand(EditingDomain domain, CommandParameter commandParameter) This method factors an AddCommand for a collection of objects into one or more primitive add command, i.e., one per unique feature.
protected EStructuralFeature	getChildFeature(Object object, Object child) This returns the most appropriate feature of the object into which the given child could be added.
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 createCommand(java.lang.Object, org.eclipse.emf.edit.domain.EditingDomain, java.lang.Class, org.eclipse.emf.edit.command.CommandParameter).

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

MappingItemProvider

public MappingItemProvider(AdapterFactory adapterFactory)

This constructs an instance from a factory and a notifier.

Method Detail

getPropertyDescriptorsForHelper

public void getPropertyDescriptorsForHelper(Mapping mapping)

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 createCommand(java.lang.Object, org.eclipse.emf.edit.domain.EditingDomain, java.lang.Class, org.eclipse.emf.edit.command.CommandParameter).

Overrides:

getChildFeature

protected EStructuralFeature getChildFeature(Object object,

Description copied from class: ItemProviderAdapter

This returns the most appropriate feature of the object into which the given child could be added. This default implementation first calls the deprecated getChildReference, for backwards compatibility. If that does not yield a non-null result, it returns the first feature returned by getChildrenFeatures that has a type compatible with the child. You can override this to return a better result or to compute it more efficiently.
