Class CurveSegmentImpl

java.lang.Object
  org.deegree.model.spatialschema.CurveSegmentImpl

All Implemented Interfaces:

java.io.Serializable, CurveSegment, GenericCurve

Direct Known Subclasses:

LineStringImpl

public abstract class CurveSegmentImpl
extends java.lang.Object
implements CurveSegment, java.io.Serializable

default implementation of the CurveSegment interface from package deegree.model.spatialschema. the class is abstract because it should be specialized by derived classes LineString for example
