Class MergeFeaturesActionBean

java.lang.Object

nl.b3p.viewer.stripes.MergeFeaturesActionBean

All Implemented Interfaces:

net.sourceforge.stripes.action.ActionBean

@UrlBinding(value="/action/feature/merge")
@StrictBinding
public class MergeFeaturesActionBean
extends Object
implements net.sourceforge.stripes.action.ActionBean

Merge two features, A and B so that A will have the combined geometry of A and B and B will cease to exist. A may be a new feature if that strategy is chosen.

Handles the feature creation/update/deletion strategy. You may want to override this in a subclass to handle workflow.

Parameters:

featureA - the feature that is about to be merged into

featureB - the feature that is about to be merged to A

newGeom - the new geometry that is the result of merging A and B geometries

filterA - filter to get at feature A

filterB - filter to get at feature B

localStore - the store we're working against

localStrategy - the strategy in use

Returns:

A list of FeatureIds is returned, one for each feature in the order created. However, these might not be assigned until after a commit has been performed.

Throws:

Exception - if an error occurs modifying the data source, converting the geometry or an illegal argument was given

afterMerge

protected void afterMerge(List<org.opengis.filter.identity.FeatureId> ids)

Called after the merge is completed and commit was performed. Provides a hook for postprocessing.

Parameters:

ids - The list of committed feature ids
