Interface IMultiShape

All Superinterfaces:
Cloneable, IGeometry, Serializable
All Known Implementing Classes:
Region, Ring
public interface IMultiShape extends IGeometry

In contradiction to the relation of the IPolyCurve to the ICurve interfaces, the IMultiShape interface does not extend the IShape interface. Anyhow, they share their interface methods. You can test an IGeometry for containment using the contains(IGeometry) method and the outline segments can be retrieved via the getOutlineSegments() method.

  • Method Details

    • contains

      boolean contains(IGeometry g)
      Checks if the given IGeometry is fully contained by this IMultiShape.
      Parameters:
      g - The IGeometry which is tested for containment.
      Returns:
      true if the IGeometry is contained by this IMultiShape, otherwise false

    • getOutlines

      ICurve[] getOutlines()

      Computes the outlines of this IMultiShape.

      The outlines are returned as an array of ICurves. For every closed outline of this IMultiShape one ICurve is returned.

      Returns:
      an array of ICurves, one for each closed outline

    • getOutlineSegments

      ICurve[] getOutlineSegments()

      Computes the outline segments of this IMultiShape.

      Each ICurve segment of the outline of the internal IShape s can be either an inner segment or an outer segment. This method extracts only the outer segments. The segments bordering voids are considered to be outer segments, too.

      Returns:
      the outline segments of this IMultiShape

    • getShapes

      IShape[] getShapes()
      Returns the IShapes that constitute this IMultiShape.
      Returns:
      an array of IShapes, representing the parts that make up this IMultiShape.
