public class BufferPlugIn
extends AbstractThreadedUiPlugIn

PlugIn performing buffer operations authorized by JTS BufferOp class. It takes a number of options :

• union selected features or all features of a selected layers
• buffer size
• number of segments by quadrant

Method Details

initialize

public void initialize(PlugInContext context)
                throws Exception

Description copied from class: AbstractUiPlugIn

Method to be overridden by implementations to initialize the plug-in. Plug-ins must invoke super.initialize().

Specified by:

initialize in interface PlugIn

Overrides:

initialize in class AbstractUiPlugIn

Parameters:

context - The plug-in context.

Throws:

Exception - if an exception occur during initialization

createEnableCheck

public static MultiEnableCheck createEnableCheck(WorkbenchContext workbenchContext)

execute

public boolean execute(PlugInContext context)
                throws Exception

Description copied from class: AbstractUiPlugIn

Method to be overridden by implementations to execute the plug-in.

Specified by:

execute in interface PlugIn

Overrides:

execute in class AbstractUiPlugIn

Parameters:

context - The plug-in context.

Returns:

true if the PlugIn has been executed

Throws:

Exception - if an Exception occurs during execution

run

public void run(TaskMonitor monitor,
 PlugInContext context)
         throws Exception

Description copied from interface: ThreadedPlugIn

Runs the task. This method will be executed in a separate thread, so that the GUI remains responsive (but only partially so, as a modal progress dialog will be in the way). Don't call GUI classes in this method as it is not executed on the GUI thread.

Parameters:

monitor - context to which this task can report its progress and check whether a party has requested its cancellation

context - context of this PlugIn

Throws:

Exception - if an Exception occurs during the run

updateControls

protected void updateControls(PlugInContext context,
 MultiInputDialog dialog,
 boolean useSelection)
