Class TLcdICAORunwayPainter

java.lang.Object
com.luciad.ais.symbology.icao.TLcdICAORunwayPainter
All Implemented Interfaces:
ILcdCloneable, ILcdPropertyChangeSource, ILcdGXYPainter, ILcdGXYPainterProvider, Serializable, Cloneable
public class TLcdICAORunwayPainter extends Object implements ILcdGXYPainter, ILcdGXYPainterProvider
This painter paints ILcdRunway objects according to the ICAO guidelines for aeronautical charts. Each runway with two or more points will be painted as a rectangle. This rectangle is constructed by using the first and the last point of the runway. Runways with less than two points will not be painted; nonetheless, a valid ILcdGXYPainter will be returned for them when invoking getGXYPainter().

If a surface type property is available for the runway objects, the surface type is used to determine a paint style for the rectangle, following the ICAO guidelines:

  • If the surface type is hard, the rectangle will be filled.
  • If the surface type is soft, the rectangle will be dotted.
If the surface type property is not available, the rectangle will be outlined (not filled). To allow this painter to retrieve the surface type for runways, the surface type expression must be set through setSurfaceTypeExpression.

This painter evaluates its expressions using an instance of TLcdDataObjectExpressionLanguage.

    • setObject

      public void setObject(Object aObject)
      Description copied from interface: ILcdGXYPainter
      Sets the Object for which the representation shall be handled by this painter.

      Setting the object on the painter may have an effect on the internal state of the painter, for example, the color to use.

      When the object is set to a painter, the context parameter in subsequent calls to methods in this class must contain a layer that contains this object and for which the painter for this object is this painter.

      Specified by:
      setObject in interface ILcdGXYPainter
      Parameters:
      aObject - the object for which the representation shall be handled by this painter.

    • boundsSFCT

      public void boundsSFCT(Graphics aGraphics, int aSequenceNumber, ILcdGXYContext aContext, ILcd2DEditableBounds aILcd2DEditableBounds) throws TLcdNoBoundsException
      Description copied from interface: ILcdGXYPainter
      Sets the supplied bounds (in view coordinates, pixels) so that it encompasses the representation of the object in the given mode taking into account the given context.

      If this method returns without exception the bounds argument must encompass the representation of the object. A point outside the bounds will not be contained within the painted object.

      The bounds returned in this method can be seen as the equivalent in the view space of the bounds in the model space for ILcdBounded objects.

      Specified by:
      boundsSFCT in interface ILcdGXYPainter
      Parameters:
      aGraphics - the Graphics on which the representation of the object is painted
      aSequenceNumber - the mode the object is represented in (see class documentation). For example, an object may be represented differently in SELECTED mode compared to DEFAULT mode. The returned bounds of the representation must take this different representation into account.
      aContext - the context for which the representation of the object is painted. It contains amongst others the transformations from model to world and world to view.
      aILcd2DEditableBounds - the bounds that must be adapted to encompass the representation of the object in the given mode and context. These bounds must not be taken into account when the method has thrown an exception.
      Throws:
      TLcdNoBoundsException - if no bounds can be determined for the representation of the object. This can happen when the object does not have a representation in the given context, for example when it is located in a part of the world which is not visible in the current view.

    • isTouched

      public boolean isTouched(Graphics aGraphics, int aSequenceNumber, ILcdGXYContext aContext)
      Description copied from interface: ILcdGXYPainter
      Checks if the representation of the object in the given mode is touched at the location as defined in the supplied context.

      The location that must be taken into account to check whether the representation is touched can be retrieved from the context passed with the methods ILcdGXYContext.getX() and ILcdGXYContext.getY(). If the check is part of an ongoing operation of user interaction, for example, when the mouse is being dragged, the location of the start of the operation can also be taken into account using the methods ILcdGXYContext.getDeltaX() and ILcdGXYContext.getDeltaY(). The context contains the transformations required to convert this location into the equivalent location in model space. Implementations of this interface usually follow either of the following patterns:

      • transform the location of the interaction back to model space and compare the coordinates with the object in model space.
      • transform the location to world space and compare with a world representation of the object. This forces the painter into caching a world representation of the object. Caching a view representation of an object is not very practical as it would have to change whenever the view's scale changes or when it is panned. A world representation of an object only changes when the view's XYWorldReference changes, which happens less frequently.

      As the mode influences the way an object is represented, it must also be taken into account when checking whether that representation is being touched. When the mode contains CREATING, RESHAPING or TRANSLATING which indicate that the object must be represented in a state for an ongoing operation, the location of the start of the operation may be taken into account as mentioned above. The painting result can take into account multiple locations, to respond to, for example, multi-touch input. When the mode contains SELECTED, the painter should also check if the non-selected representation is touched, since these are always painted on top of each other.

      The boundsSFCT is often used to speed up the performance of this method as a location outside these bounds can never touch the representation of the object.

      Note that this method does not give an indication of what part of the object is touched. It is up to the painter implementations to provide methods to make this distinction. The method does also not indicate what sensitivity must be applied when checking if an object is touched. It is up to the implementation to decide what should be the maximum distance between the location given in the context and the closest relevant point or area of the representation of the object.

      Specified by:
      isTouched in interface ILcdGXYPainter
      Parameters:
      aGraphics - the Graphics on which the representation of the object is painted
      aSequenceNumber - the mode the object is represented in
      aContext - contains the location of the interaction and the transformations to convert this location into model coordinates
      Returns:
      true if the representation of the object in the given mode is touched by the location as defined in the context passed, false otherwise

    • addPropertyChangeListener

      public void addPropertyChangeListener(PropertyChangeListener aPropertyChangeListener)
      Description copied from interface: ILcdPropertyChangeSource

      Registers the given PropertyChangeListener to be notified when this object's properties change.

      In case you need to register a listener which keeps a reference to an object with a shorter life-time than this change source, you can use a ALcdWeakPropertyChangeListener instance as property change listener.

      Specified by:
      addPropertyChangeListener in interface ILcdPropertyChangeSource
      Parameters:
      aPropertyChangeListener - The listener to be notified

    • anchorPointSFCT

      public void anchorPointSFCT(Graphics aGraphics, int aSequenceNumber, ILcdGXYContext aContext, Point aPoint) throws TLcdNoBoundsException
      Description copied from interface: ILcdGXYPainter
      Moves the Point passed to the location (in view coordinates, pixels) of the anchor point of the representation of the object in the given mode taking into account the given context.

      The anchor point is an important point of the representation, typically the point which would be used when the object would be represented as a single point. The anchor point is mostly used to attach extra information to the representation of an object, for example, using labels. A typical implementation of this method for painters which can handle ILcdShape objects is the location of the focus point of the shape.

      Specified by:
      anchorPointSFCT in interface ILcdGXYPainter
      Parameters:
      aGraphics - the Graphics on which the representation of the object is painted
      aSequenceNumber - the mode the object is painted in (see class documentation)
      aContext - the context for which the representation of the object is painted. It contains amongst others the transformations from model to world and world to view.
      aPoint - the point that has to be moved to the location of the anchor point of the representation of the object. This point must not be taken into account when the method has thrown a TLcdNoBoundsException.
      Throws:
      TLcdNoBoundsException - if no anchor point can be determined for the representation of the object. This can be when the object does not have a representation in the given context, for example when it is located in a part of the world which is not visible in the projection as set in the views world reference.
