All Implemented Interfaces:

EnableChecked, Iconified, PlugIn, Recordable, ShortcutEnabled, ThreadedPlugIn, ActionListener, EventListener

public class ExtractLayersByGeometry
extends AbstractThreadedUiPlugIn

This plugin split a layer into several layers when its features have different geometry dimensions. It can produce a maximum of 4 layers

• Empty geometries
• Punctual geometries
• Linear geometries
• Polygonal geometries

Rules followed to spread features into the 4 layers :

• Empty GeometryCollection's are copied into empty-geometries layer
• Non-empty GeometryCollections are exploded into simple geometry features
• Empty simple features are copied into the layer corresponding to their dimension
• Non-empty simple features are copied into the layer corresponding to their dimension

Method Detail

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

ThreadedPlugIn

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

getName

public String getName()

Description copied from class: AbstractUiPlugIn

Get the name of the plug-in. If a name was not specified ask super class.

Specified by:

getName in interface PlugIn

Overrides:

getName in class AbstractUiPlugIn

Returns:

The plug-in name.
