getBounds in class TLcdGML31AbstractCurveSegment

Returns:

the ILcdBounds by which the geometry of this ILcdBounded object is bounded.

getInterpolationAttr

public ELcdGML31CurveInterpolation getInterpolationAttr()

Returns the value of the property that maps to the interpolation attribute.

The attribute "interpolation" specifies the curve interpolation mechanism used for this segment. This mechanism uses the control points and control parameters to determine the position of this curve segment. For an GeodesicString the interpolation is fixed as "geodesic".

Returns:

the value of the INTERPOLATION_ATTR_PROPERTY property.

setInterpolationAttr

public void setInterpolationAttr(ELcdGML31CurveInterpolation aValue)

Sets the value of the property that maps to the interpolation attribute.

The attribute "interpolation" specifies the curve interpolation mechanism used for this segment. This mechanism uses the control points and control parameters to determine the position of this curve segment. For an GeodesicString the interpolation is fixed as "geodesic".

Parameters:

aValue - the value to set for the INTERPOLATION_ATTR_PROPERTY property.

getPosGroup

public Object getPosGroup()

Returns the value of the property that maps to the choice between the posList and pos and pointProperty elements.

The possible values for this property are instances of

• TLcdGML31DirectPositionList
• List<TLcdGML31DirectPosition>
• List<TLcdGML31PointProperty>

Returns:

the value of the POS_GROUP_PROPERTY property.

setPosGroup

public void setPosGroup(Object aValue)

Sets the value of the property that maps to the choice between the posList and pos and pointProperty elements.

The possible values for this property are instances of

• TLcdGML31DirectPositionList
• List<TLcdGML31DirectPosition>
• List<TLcdGML31PointProperty>

Parameters:

aValue - the value to set for the POS_GROUP_PROPERTY property.

getNumDerivativeInterior

public long getNumDerivativeInterior()

Returns the value of the property that maps to the numDerivativeInterior attribute.

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. A value of "n" for any integer means the function and its first n derivatives are continuous: "C n " continuity. NOTE: Use of these values 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.

Returns:

the value of the NUM_DERIVATIVE_INTERIOR_PROPERTY property.

setNumDerivativeInterior

public void setNumDerivativeInterior(long aValue)

Sets the value of the property that maps to the numDerivativeInterior attribute.

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. A value of "n" for any integer means the function and its first n derivatives are continuous: "C n " continuity.

Parameters:

aValue - the value to set for the NUM_DERIVATIVE_INTERIOR_PROPERTY property.

getNumDerivativesAtEnd

public long getNumDerivativesAtEnd()

Returns the value of the property that maps to the numDerivativesAtEnd attribute.

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. NOTE: Use of these values is only appropriate when the basic curve definition is an underdetermined system.

getNumDerivativesAtStart

public long getNumDerivativesAtStart()
