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

setCategoryName

public void setCategoryName(java.lang.String value)

initialize

public void initialize(PlugInContext context)
                throws java.lang.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:

java.lang.Exception

createEnableCheck

public static MultiEnableCheck createEnableCheck(WorkbenchContext workbenchContext)

execute

public boolean execute(PlugInContext context)
                throws java.lang.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 action completed, false if it was aborted. Used by ThreadedPlugIns to indicate that their #run method needn't be called next.

Throws:

java.lang.Exception - if a problem occurs during plug-in execution

run

public void run(TaskMonitor monitor,
                PlugInContext context)
         throws java.lang.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

Throws:

java.lang.Exception

updateControls

protected void updateControls(MultiInputDialog dialog)
