  ilog.views.maps.datasource.IlvMapDataSource
      ilog.views.maps.datasource.IlvHierarchicalDataSource
          ilog.views.maps.datasource.IlvSplitDataSource

All Implemented Interfaces:

IlvPersistentObject

public class IlvSplitDataSource
extends IlvHierarchicalDataSource

This data source sorts all the graphical objects stored in a specific map layer. It creates a new tree from the map layers, according to the selection made by the criterion filter. This data source goes through all the objects in the manager layer, using the criterion filter to return a value. Each different value found triggers the creation of a single map layer in the layer tree.

Since:

JViews 8.0
