public abstract class AbstractPlugIn
extends Object
implements PlugIn

Default implementation of PlugIn, with useful functions for auto-generating a name, converting a PlugIn into an ActionListener (for use with JButtons, for example), and supporting undo.

Method Detail

execute

protected void execute(UndoableCommand command,
           PlugInContext context)

initialize

public void initialize(PlugInContext context)
                throws Exception

Description copied from interface: PlugIn

Called when Workbench starts up to allow plugins to initialize themselves.

Specified by:

initialize in interface PlugIn

Throws:

Exception

execute

public boolean execute(PlugInContext context)
                throws Exception

Description copied from interface: PlugIn

Performs the action for this plugin. For threaded plugins with dialogs, this method contains the code to invoke the dialog. If the user cancels the dialog, this method should return false to prevent the run method from being called.

Specified by:

execute in interface PlugIn

Returns:

true if the action completed, false if it was aborted. Used by ThreadedPlugIns to indicate that their #run method needn't be called next.

Throws:

Exception - if a problem occurs during plug-in execution

getName

public String getName()

Description copied from interface: PlugIn

Returns a very brief description of this PlugIn e.g. for display as a menu item

Specified by:

getName in interface PlugIn

Returns:

the class name, minus "PlugIn", with spaces inserted at the appropraite point before each uppercase+lowercase and lowercase+uppercase combination.

createName

public static String createName(Class plugInClass)

toActionListener

public static ActionListener toActionListener(PlugIn plugIn,
                              WorkbenchContext workbenchContext,
                              TaskMonitorManager taskMonitorManager)

Parameters:

taskMonitorManager - can be null if you do not wish to use the Task Monitor progress-reporting framework

execute

public static void execute(UndoableCommand command,
           LayerManagerProxy layerManagerProxy)

toString

public String toString()

Overrides:

toString in class Object

reportNothingToUndoYet

protected void reportNothingToUndoYet(PlugInContext context)

Indicates that this plug-in either (1) is undoable but hasn't modified the system yet or (2) does not modify the system. In either case, the undo history will be preserved. If this method is not called, then this plug-in will be assumed to be non-undoable, and the undo history will be truncated.

isRollingBackInvalidEdits

protected boolean isRollingBackInvalidEdits(PlugInContext context)
