Constructor Detail

SetConnectionEndsCommand

public SetConnectionEndsCommand(org.eclipse.emf.transaction.TransactionalEditingDomain editingDomain,
                                java.lang.String label)

constructor

Parameters:: editingDomain - the editing domain through which model changes are made; label - the command label

Method Detail

getAffectedFiles

public java.util.List getAffectedFiles()

Description copied from class: AbstractTransactionalCommand

Returns the IFiles for resources that may be modified when the operation is executed, undone or redone.

Specified by:: getAffectedFiles in interface ICommand
Overrides:: getAffectedFiles in class AbstractTransactionalCommand

Returns:: the list of IFiles that will be modified

getEdgeAdaptor

public 
IAdaptable getEdgeAdaptor()

gets the edge adaptor.

Returns:: the edge adapter

getNewSourceAdaptor

public 
IAdaptable getNewSourceAdaptor()

gets the new source adaptor.

Returns:: new source adaptor.

getNewTargetAdaptor

public 
IAdaptable getNewTargetAdaptor()

gets the new target adaptor.

Returns:: the new target adaptor.

setEdgeAdaptor

public void setEdgeAdaptor(
IAdaptable edgeAdaptor)

Sets the edge adaptor.

Parameters:: edgeAdaptor - the edgeAdaptor to set

setNewSourceAdaptor

public void setNewSourceAdaptor(
IAdaptable newSourceAdaptor)

Sets the new source adaptor.

Parameters:: newSourceAdaptor - The newSourceAdaptor to set

setNewTargetAdaptor

public void setNewTargetAdaptor(
IAdaptable newTargetAdaptor)

Sets the new target adaptor.

Parameters:: newTargetAdaptor - The newTargetAdaptor to set

doExecuteWithResult

protected 
CommandResult doExecuteWithResult(
IProgressMonitor progressMonitor,
                                            
IAdaptable info)
                                     throws 
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
