public class IntersectPolygonsOneLayerPlugIn
extends ThreadedBasePlugIn

Author:

sstein url www.openjump.org curentdate 27 May 2010 license GPL2 Intersects polygons in one layer. It therefore calculates all geometric intersections between the polygons. Afterwards the attributes are transferred. The later step assumes that a new created intersection polygon has at max only one correspondent polygon per layer.

Method Detail

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

Overrides:

initialize in class AbstractPlugIn

Parameters:

context - context of the PlugIn

Throws:

Exception - if an exception occur during initialization

execute

public boolean execute(PlugInContext context)
                throws Exception

Description copied from class: AbstractPlugIn

Execute the PlugIn.

Specified by:

execute in interface PlugIn

Overrides:

execute in class AbstractPlugIn

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

Overrides:

getName in class AbstractPlugIn

Returns:

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

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

resetFeatureValuesToNaN

public static Feature resetFeatureValuesToNaN(Feature f)

All values are set to NaN.

Parameters:

f - the Feature whose attributes must be set to NaN

Returns:

a clone of f where all numeric and string attributes are set to NaN
