connect
Adapts this arc such that its start point and end point coincide with the given start and end point. Note that this modification is only observable when this object is accessed through the
ILcd2DEditableCircularArcByCenterPoint
interface. When accessed using the GML or the ILcdDataObject API, the original state is used.This method should be used for arcs that are part of an
ILcdCompositeCurve
and that have inaccurate coordinates. Drawing such arcs directly may result in exceptions being thrown while painting because theILcdCompositeCurve
contract is not observed. TheILcdCompositeCurve
contract explicitly states that the end point of a curve member should coincide with the start point of the next curve member.In case the difference between the computed start/end point and the given start/end point is too large,
false
is returned. In that case, no adaptation is done. Otherwise,true
is returned. Parameters:
aStart
 the start point that this curve should have (seegetStartPoint()
)aEnd
 the end point that this curve should have (seegetEndPoint()
) Returns:
 true if the curve is adapted to have its start and end point coincide with the given points

orTLcdXYBounds
. Specified by:

 the
ILcdBounds
by which the geometry of thisILcdBounded
object is bounded.

getInterpolationAttr
Returns the value of the property that maps to theinterpolation
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.

 Returns:
 the value of the
INTERPOLATION_ATTR_PROPERTY
property.

setInterpolationAttr

getNumDerivativeInterior
public long getNumDerivativeInterior()Returns the value of the property that maps to thenumDerivativeInterior
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 thenumDerivativeInterior

property.

public long getNumDerivativesAtEnd()Returns the value of the property that maps to thenumDerivativesAtEnd
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.

public void setNumDerivativesAtEnd(long aValue) Sets the value of the property that maps to thenumDerivativesAtEnd
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. 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.
 Parameters:
aValue
 the value to set for theNUM_DERIVATIVES_AT_END_PROPERTY
property.

getNumDerivativesAtStart
public long getNumDerivativesAtStart()Returns the value of the property that maps to thenumDerivativesAtStart
attribute.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. 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_DERIVATIVES_AT_START_PROPERTY
property.
