Interface ExtendLineOperation

All Known Implementing Classes:

ArcExtendLineOperation, CurveExtendLineOperation

public interface ExtendLineOperation

Represents an operation to extend curve.

Method Summary

Modifier and Type	Method and Description
Curve	extendLine(Curve curveToBeExtended, Point insertedPoint, FeatureSelection boundaryObjects) Extend line to boundary objects received as parameters.Inserted point is the point inserted by user.It is used to determinate what side of curve it must extend.If curveToBeExtended does not intersect with any geometry, the geometry will not be modified.
Curve	extendLine(Curve curveToBeExtended, Point insertedPoint, Geometry boundaryObject) Extend line to boundary objects received as parameters.Inserted point is the point inserted by user.It is used to determinate what side of curve it must extend.If curveToBeExtended does not intersect with any geometry, the geometry will not be modified.

Method Detail

extendLine

Curve extendLine(Curve curveToBeExtended,
                 Point insertedPoint,
                 FeatureSelection boundaryObjects)
          throws GeometryOperationNotSupportedException,
                 GeometryOperationException,
                 DataException,
                 GeometryException

Extend line to boundary objects received as parameters.Inserted point is the point inserted by user.It is used to determinate what side of curve it must extend.If curveToBeExtended does not intersect with any geometry, the geometry will not be modified.

Parameters:

curveToBeExtended - Curve to be extended.

insertedPoint - Point inserted by user to determinate what side of curve must be extended.

boundaryObjects - If curveToBeExtended intersects with some boundary object, it will be extend to it. If there are several boundary objects that intersects with curveToBeExtended, it will be extended to nearest point.

Returns:

extended line.

Throws:

GeometryOperationNotSupportedException

GeometryOperationException

DataException

GeometryException
