Class GraphicFenceParameters

  • public final class GraphicFenceParameters
extends FenceParameters
    Geotrigger fence parameters data created from graphics.

    The graphics used to create a GraphicFenceParameters provide a set of geometries and attributes that define targets for a FenceGeotrigger condition. For example, if the condition is "notify me when my position comes within 50 meters of one of my target areas", the fence data is "my target areas".

    A GraphicFenceParameters allows you to track a specific set of Graphic objects: these can be a selection of the graphics from a GraphicsOverlay or graphics that are not displayed on a GeoView. If you wish to track all of the graphics displayed in a GraphicsOverlay, use a GraphicsOverlayFenceParameters.

    A GraphicFenceParameters is created using a list of Graphic objects. The graphics can have point, line, or polygon geometry. A FenceParameters.getBufferDistance() must be supplied for points or lines.

      • GraphicFenceParameters

        public GraphicFenceParameters​(Iterable<Graphic> graphics)
        Creates a GraphicFenceParameters that will apply a buffer distance to the supplied graphics.
        Parameters:
        graphics - a set of graphics that should be used as fences
        Throws:
        IllegalArgumentException - if graphics is null

        public GraphicFenceParameters​(Iterable<Graphic> graphics,
                              double bufferDistance)
        Creates a GraphicFenceParameters that will apply a buffer distance to any graphics that are added to getGraphics().
        Parameters:
        graphics - a set of graphics that should be used as fences
        bufferDistance - a buffer distance in meters to apply to the graphics when checking if a Geotrigger condition is met
        Throws:
        IllegalArgumentException - if graphics is null

      • GraphicFenceParameters

        public GraphicFenceParameters​(double bufferDistance)
        Creates a GraphicFenceParameters that will apply a buffer distance to any graphics that are added to getGraphics().
        Parameters:
        bufferDistance - a buffer distance in meters to apply to graphics when checking if a Geotrigger condition is met

    • Method Detail

      • getGraphics

        public List<Graphic> getGraphics()
        Gets the graphics to use in the GraphicFenceParameters.

        This collection will be tracked when monitoring a Geotrigger such that any graphics that are added will be included and any that are removed will no longer be checked.

        The Geometry of each Graphic will be buffered by the buffer distance.

        Returns:
        the graphics to use in the GraphicFenceParameters
