Constructor Detail

AbstractChartNode

public AbstractChartNode(AbstractChartNode parent)

Method Detail

clone

protected final List clone(List in,
                           Map hashClonedNode)

Returns a deep copy of a vector of ChartNode's.

clone

protected Object clone(Map hashClonedNode)

Returns a deep-copy clone of this node. Each class derived from this class should override this function IF the derived class contains ChartNode objects or double[] arrays as member data. The overriden function should call this function and then clone each of its ChartNode data members. For example, in AxisXY we have

        protected Object clone(Hashtable hashClonedNode)
        {
            AxisXY t = (AxisXY)super.clone(hashClonedNode);
            t.axisX = (Axis1D)axisX.clone(hashClonedNode);
            t.axisY = (Axis1D)axisY.clone(hashClonedNode);
            return t;
        }
        

Parameters:

hashClonedNode - Hashtable of nodes that have already been cloned. We need to clone each ChartNode exactly once even if multiple references to it exist in the graphics tree. In this hashtable keys are existing ChartNode objects and values are their clones.

clone

protected final Map clone(Map hashIn,
                          Map hashClonedNode)

Returns a deep copy of a Hashtable. We assume the keys are immutable (e.g. Strings) and so do not have to be cloned. We cannot just use Hashtable.clone() because we want to specially handle cloning of ChartNodes that may occur in the hashtable. (Need to clone each ChartNode exactly once even if multiple references to it exist in the graphics tree.)

clone

protected Object clone(Object value,
                       Map hashClonedNode)

Returns a deep copy of an Object. Handles non-immutable object types ChartNode, Hashtable, Vector, double[], String[], and int[]. (Immutable objects can just be reused, they do not have to be cloned.)

If other non-immutable object types are used in the tree then the nodes where they are defined should override this function to handle the cloning. The new function calls super.clone(value, hashClonedNode) for values handled here.
