Constructor Detail

SystemKillProcessAction

public SystemKillProcessAction(Shell shell)

Constructor for subclass

Method Detail

updateSelection

public boolean updateSelection(IStructuredSelection selection)

We override from parent to do unique checking...

We simply ensure every selected object is an IRemoteProcess

Overrides:

updateSelection in class SystemBaseAction

See Also:

SystemBaseAction.updateSelection(IStructuredSelection)

getDialogValue

protected Object getDialogValue(Dialog dlg)

Required by parent. It is up to the caller to call wasCancelled() and if not true, do their own killing.

Specified by:

getDialogValue in class SystemBaseDialogAction

Parameters:

dlg - The dialog object, after it has returned from open.

createDialog

protected Dialog createDialog(Shell shell)

If you decide to use the supplied run method as is, then you must override this method to create and return the dialog that is displayed by the default run method implementation.

If you override run with your own, then simply implement this to return null as it won't be used.

Specified by:

createDialog in class SystemBaseDialogAction

See Also:

SystemBaseDialogAction.run()

getRunnableContext

protected IRunnableContext getRunnableContext()

Get an IRunnable context to show progress in. If there is currently a dialog or wizard up with a progress monitor in it, we will use this, else we will create a progress monitor dialog.

run

public void run(IProgressMonitor monitor)
         throws InvocationTargetException,
                InterruptedException

Method required by IRunnableWithProgress interface. Allows execution of a long-running operation modally by via a thread. In our case, it runs the kill operation with a visible progress monitor

Specified by:

run in interface IRunnableWithProgress

Throws:

InvocationTargetException

InterruptedException

doKill

protected boolean doKill(IProgressMonitor monitor,
                         String signal,
                         IRemoteProcess process)
                  throws Exception

Parameters:

monitor - Usually not needed

signal - the signal to be sent to the remote process

process - the process to send the signal to

Throws:

Exception

killComplete

public void killComplete()

Called after all the copy/move operations end, be it successfully or not. Your opportunity to display completion or do post-copy selections/refreshes

getAffectedFilters

protected List getAffectedFilters(Object[] processesDeathRow,
                                  ISubSystem subSystem)

Returns a list of all the filters that are affected by killing the objects in processesDeathRow.

Parameters:

processesDeathRow - the objects that will be sent a kill signal

subSystem - the subsystem to search

Returns:

a list of the affected filters

populateSelectedObjects

protected void populateSelectedObjects()

getKillingMessage

protected SystemMessage getKillingMessage()

getKillingMessage

protected SystemMessage getKillingMessage(String signal,
                                          String processName)

Get the specific "kill" message

showOperationMessage

protected void showOperationMessage(Exception exc,
                                    Shell shell)

Helper method to show an error message resulting from the attempted operation.

showOperationErrorMessage

protected void showOperationErrorMessage(Shell shell,
                                         Throwable exc)

Show an error message when the operation fails. Shows a common message by default. Overridable.

showOperationErrorMessage

protected void showOperationErrorMessage(Shell shell,
                                         SystemMessageException exc)

Show an error message when the operation fails. Shows a SystemMessage that was encapsulated in a SystemMessage exception Overridable.

showOperationCancelledMessage

protected void showOperationCancelledMessage(Shell shell)

Show an error message when the user cancels the operation. Shows a common message by default. Overridable.
