Interface ILcdRunway

All Superinterfaces:
Cloneable, ILcdBounded, ILcdCloneable, ILcdDataObject, ILcdPointList, ILcdPolyline, ILcdShape, Serializable
All Known Subinterfaces:
ILcdEditableRunway
All Known Implementing Classes:
TLcdFeaturedRunway, TLcdRunway
public interface ILcdRunway extends ILcdDataObject, ILcdPolyline
This interface describes the geometry and the relationships of a runway. A runway is modeled by its center line which is a polyline. Typically this polyline consists of the end points and the threshold points of the runway. A runway can be associated with 1 or to 2 runway directions.

The end point of the runway direction at position 0 should be stored at the first position of the runway center line (position 0). The end point of the runway direction at position 1 should be stored at the last position of the runway center line (position getPointCount() - 1). In other words: the physical beginning and the physical end of the runway will have the lowest index and the highest index in the polyline that determines the shape of the runway. The individual points of a runway may be of the type ILcdRunwayClinePoint, but this is not a general condition.

Attributes and relationships in AIS domain objects can be required or optional. When unspecified, an attribute or relationship is optional. Note that most optional attributes are modeled using features.

In future releases of AIS, optional attributes or relationship may be added to this interface. When this would happen, existing implementations may just return a specified default value for these new attributes or relationships (for instance 'null'). This will require a minimal effort to update existing code to a new version of AIS.

      ILcdRunwayDirection getRunwayDirection(int aIndex)
      Returns the direction at the given index.
      Parameters:
      aIndex - The index of the direction to be returned.
      Returns:
      the direction at the given index.

      int getRunwayDirectionCount()
      Returns the number of directions. The number of directions is 1 or 2.
      Returns:
      the number of runway directions.

    • getWidth

      double getWidth()
      Returns the width of the runway.
      Returns:
      the width of the runway in meter.
