Interface ILspSnappable

All Known Implementing Classes:
TLspGXYLayerAdapter, TLspGXYLayerTreeNodeAdapter, TLspLayer, TLspLayerTreeNode
public interface ILspSnappable
Determines whether the implementing object can be snapped to during edit operations. When an object is ILspSnappable, the isSnapTarget() method determines whether it should be regarded as a source for snapping points or not.

Note that the creation of snapping candidates is separate from this interface. This interface is merely used to toggle whether snapping should be applied or not for the implementing object.

The most common implementer of this interface is TLspLayer.

Since:
2012.0
