All Implemented Interfaces:
ILcdInitialLayerIndexProvider
public class TLspInitialLayerIndexProvider extends Object implements ILcdInitialLayerIndexProvider

    Method
    Description
    int
    getInitialLayerIndex(ILcdLayer aLayer, ILcdLayerTreeNode aLayerNode)
    Looks at the layer's type and determines an initial index as follows: For BACKGROUND layers, this method starts from the bottom up and inserts the new layer just below the first layer which is not also a background layer. For INTERACTIVE layers, the method starts from the bottom up and inserts the new layer just above the first layer which is not a BACKGROUND or INTERACTIVE layer. For EDITABLE layers, the method starts from the top down and inserts the new layer just below the first layer which is not a REALTIME layer. REALTIME layers are simply added at the top of the layer list.
