RepositionEObjectCommand

public RepositionEObjectCommand(org.eclipse.emf.transaction.TransactionalEditingDomain editingDomain,
                                java.lang.String label,
                                org.eclipse.emf.common.util.EList elements,

                                int displacement)

Constructs a runtime instance of RepositionEObjectCommand.

Parameters:: editingDomain - the editing domain through which model changes are made; label - label for command; elements - the list of elements in which reposition will take place; element - target element; displacement - amount of movement

Method Detail

doExecuteWithResult

protected 
CommandResult doExecuteWithResult(
IProgressMonitor progressMonitor,
                                            
IAdaptable info)

ExecutionException

Description copied from class: AbstractTransactionalCommand

Implemented by subclasses to perform the model changes. These changes are applied by manipulation of the EMF metamodel's API, not by executing commands on the editing domain's command stack.

Specified by:: doExecuteWithResult in class AbstractTransactionalCommand

Parameters:: progressMonitor - the progress monitor provided by the operation history; info - the adaptable provided by the operation history
Returns:: the result of the execution
Throws:: ExecutionException - if, for some reason, I fail to complete the operation
