All Implemented Interfaces:

public class MoveRequest

extends 
AbstractEditCommandRequest

Request to move a collections of model elements from one location to another. The request can specify the target features that should be used to contain each of the elements being moved.

If the target feature is not specified for a given element being moved, then a default feature is found in the target according to the following rules:

  • If the feature fomerly containing the moved element exists in the target element, it will be used.
  • Otherwise, the first feature in the target that can contain the moved element will be used.

elementToMove - the element to be moved

MoveRequest

public MoveRequest(org.eclipse.emf.transaction.TransactionalEditingDomain editingDomain,
                   org.eclipse.emf.ecore.EObject targetContainer,
                   org.eclipse.emf.ecore.EObject elementToMove)

MoveRequest

public MoveRequest(org.eclipse.emf.transaction.TransactionalEditingDomain editingDomain,
                   org.eclipse.emf.ecore.EObject targetContainer,
                   java.util.List elementsToMove)
Constructs a new request to move a collection of model element into a new container. The features in the target used to contain the moved elements will be derived as follows:
  • If the feature fomerly containing the moved element exists in the target element, it will be used.
  • Otherwise, the first feature in the target that can contain the moved element will be used.

Parameters:
editingDomain - the editing domain in which I am requesting to make model
targetContainer - the target container
elementsToMove - the list of EObjects to be moved.

Returns:
the container into which the element will be moved

setTargetFeature

public void setTargetFeature(org.eclipse.emf.ecore.EObject element,
                             org.eclipse.emf.ecore.EReference targetFeature)
Sets the reference feature into which an element should be moved.

Parameters:
element - the element to be moved
targetFeature - the target feature

getTargetFeature

public org.eclipse.emf.ecore.EReference getTargetFeature(org.eclipse.emf.ecore.EObject element)
Gets the feature in the target element that should contain element after it is moved.

Parameters:
element - the element to be moved
Returns:
the feature that will contain the element in the target

getElementsToEdit

public java.util.List getElementsToEdit()
Description copied from interface: IEditCommandRequest
Gets the elements that will be changed when the work is done for this request.

Specified by:
getElementsToEdit in interface IEditCommandRequest
Overrides:

Returns:
the elements that will be edited

getDefaultLabel

protected java.lang.String getDefaultLabel()

Returns:
the default label

getEditHelperContext

public java.lang.Object getEditHelperContext()
Description copied from interface: IEditCommandRequest
Gets the edit helper context for this request. The context can be an IElementType or an EObject, or an IEditHelperContext. It determines which edit helper should be used to find a command to do the work in the request.
