Interface for the gml:AbstractCurveSegmentType type.

Curve segment defines a homogeneous segment of a curve.

NOTE Use of the attributes is only appropriate when the basic curve definition is an underdetermined system. For example, line string segments cannot support continuity above C 0 , since there is no spare control parameter to adjust the incoming angle at the end points of the segment. Spline functions on the other hand often have extra degrees of freedom on end segments that allow them to adjust the values of the derivatives to support C 1 or higher continuity.

  • Method Details

    • getNumDerivativesAtStart

      int getNumDerivativesAtStart()
      Deprecated.
      The attribute "numDerivativesAtStart" specifies the type of continuity between this curve segment and its predecessor. If this is the first curve segment in the curve, one of these values, as appropriate, is ignored. The default value of "0" means simple continuity, which is a mandatory minimum level of continuity. This level is referred to as "C 0" in mathematical texts. A value of 1 means that the function and its first derivative are continuous at the appropriate end point: "C 1" continuity. A value of "n" for any integer means the function and its first n derivatives are continuous: "C n" continuity.

    • getNumDerivativesAtEnd

      int getNumDerivativesAtEnd()
      Deprecated.
      The attribute "numDerivativesAtEnd" specifies the type of continuity between this curve segment and its successor. If this is the last curve segment in the curve, one of these values, as appropriate, is ignored. The default value of "0" means simple continuity, which is a mandatory minimum level of continuity. This level is referred to as "C 0" in mathematical texts. A value of 1 means that the function and its first derivative are continuous at the appropriate end point: "C 1" continuity. A value of "n" for any integer means the function and its first n derivatives are continuous: "C n" continuity.

    • getNumDerivativesInterior

      int getNumDerivativesInterior()
      Deprecated.
      The attribute "numDerivativesInterior" specifies the type of continuity that is guaranteed interior to the curve. The default value of "0" means simple continuity, which is a mandatory minimum level of continuity. This level is referred to as "C 0" in mathematical texts. A value of 1 means that the function and its first derivative are continuous at the appropriate end point: "C 1" continuity.
