        Parameters:
        arrowLength - Length of the arrowhead as a fraction of the total line length. If the arrowhead length is 0.25, then the arrowhead length will be one quarter of the total line length.

      • getLegLength

        public double getLegLength()
        Indicates the length of legs of the graphic's base.
        Returns:
        The length of the legs of the base, as a fraction of the distance between the control points that define the base.

      • setLegLength

        public void setLegLength​(double legLength)
        Specifies the length of the legs of the graphic's base.
        Parameters:
        legLength - Length of the legs of the graphic's base, as a fraction of the distance between the control points that define the base.

      • setPositions

        public void setPositions​(java.lang.Iterable<? extends Position> positions)
        Specifies the positions of the control points that place and orient the graphic.
        Parameters:
        positions - Control points that orient the graphic. Must provide at least three points.

      • getPositions

        public java.lang.Iterable<? extends Position> getPositions()
        Indicates the positions of the control points that place and orient the graphic.
        Returns:
        positions that orient the graphic. How many positions are returned depends on the type of graphic. Some graphics require only a single position, others require many.

      • getReferencePosition

        public Position getReferencePosition()
        A position associated with the object that indicates its aggregate geographic position. The chosen position varies among implementers of this interface. For objects defined by a list of positions, the reference position is typically the first position in the list. For symmetric objects the reference position is often the center of the object. In many cases the object's reference position may be explicitly specified by the application.
        Returns:
        the object's reference position, or null if no reference position is available.

      • applyDelegateOwner

        protected void applyDelegateOwner​(java.lang.Object owner)
        Invoked each frame to apply to the current delegate owner to all renderable objects used to draw the graphic. This base class will apply the delegate owner to Label objects. Subclasses must implement this method to apply the delegate owner to any Renderables that they will draw in order to render the graphic.
        Specified by:
        applyDelegateOwner in class AbstractTacticalGraphic
        Parameters:
        owner - Current delegate owner.

        position2 - The second control point that defines the graphic base.
        orientationPos - A point on the arrow head side of the graphic. The legs of the base will point away from this position.
        Returns:
        Positions that define the graphic's base.
