Method Detail

run

public void run()

Description copied from class: SystemBaseAction

This is the method called when the user selects this action. Child classes need to override this. If you need the parent shell, call getShell. If you need to know the current selection, call getSelection(), or getFirstSelection() followed by getNextSelection() until null is returned.

Specified by:

run in interface IAction

Overrides:

run in class SystemBaseAction

See Also:

Action.run()

updateSelection

public boolean updateSelection(IStructuredSelection selection)

Called when the selection changes in the systems view. This determines the input object for the command and whether to enable or disable the action.

Overrides:

updateSelection in class SystemBaseAction

Parameters:

selection - the current seleciton

Returns:

whether to enable or disable the action

getActionLabelForSingleSelection

protected String getActionLabelForSingleSelection()

Extending classes must override this method, otherwise when there is one selection, the action label will be "Extract to xxxx", where xxxx is a dynamically created directory name. Note: you can also eliminate this behaviour by overriding the updateSelection method.

Returns:

Set this to return the normal action label if you don't want the name dynamically created.

getExtractedName

protected String getExtractedName(IRemoteFile selection)

getRunnableContext

protected IRunnableContext getRunnableContext(Shell shell)
