Class RadialLayoutAlgorithm

  • All Implemented Interfaces:
    ILayoutAlgorithm

    public class RadialLayoutAlgorithm
    extends java.lang.Object
    implements ILayoutAlgorithm
    This layout will take the given entities, apply a tree layout to them, and then display the tree in a circular fashion with the roots in the center.

      • applyLayout

        public void applyLayout​(LayoutContext layoutContext,
                                boolean clean)
        Description copied from interface: ILayoutAlgorithm
        Makes this algorithm perform layout computation and apply it to its context.
        Specified by:
        applyLayout in interface ILayoutAlgorithm
        Parameters:
        layoutContext - The LayoutContext that provides all relevant information about what to layout.
        clean - if true the receiver should assume that the layout context has changed significantly and recompute the whole layout even if it keeps track of changes with listeners. False can be used after dynamic layout in a context is turned back on so that layout algorithm working in background can apply accumulated changes. Static layout algorithm can ignore this call entirely if clean is false.
      • setRangeToLayout

        public void setRangeToLayout​(double startDegree,
                                     double endDegree)
        Set the range the radial layout will use when applyLayout(LayoutContext, boolean) is called. Both values must be in radians.
        Parameters:
        startDegree - The start angle for this algorithm (in degree).
        endDegree - The end angle for this algorithm (in degree).
      • isResizing

        public boolean isResizing()
        Returns:
        true if this algorithm is set to resize elements
      • setResizing

        public void setResizing​(boolean resizing)
        Parameters:
        resizing - true if this algorithm should resize elements (default is false)
