  • All Implemented Interfaces:
    Drawing

    public abstract class UnplannedDrawing
    extends java.lang.Object
    implements Drawing
    Convenience partial implementation of Drawing where no plan is used. Concrete impleentations have to provide an implementation of the plan-less paintData(Paper,DataStore) method.

      • calculatePlan

        public java.lang.Object calculatePlan​(java.lang.Object[] knownPlans,
                                              DataStore dataStore)
        Returns null.
        Specified by:
        calculatePlan in interface Drawing
        Parameters:
        knownPlans - list of zero or more plans that may have been previously calculated by this class
        dataStore - data-bearing object
        Returns:
        plan to present to the paintData method
      • paintData

        public void paintData​(java.lang.Object plan,
                              Paper paper,
                              DataStore dataStore)
        Specified by:
        paintData in interface Drawing
        Parameters:
        plan - drawing plan, from calculatePlan
        paper - graphics destination
        dataStore - data-bearing object
      • getReport

        public ReportMap getReport​(java.lang.Object plan)
        Description copied from interface: Drawing
        Obtains information associated with the plot. The plan argument must be the result of an earlier call to this object's Drawing.calculatePlan(java.lang.Object[], uk.ac.starlink.ttools.plot2.data.DataStore) method. The hasReports method of the corresponding Plotter indicates whether the return value may contain general-interest reports; special-purpose reports may be returned in any case.

        If there is nothing interesting to report, which will often be the case, the return value may be null, which is shorthand for an empty map.

        This ought not to be an expensive operation.

        Specified by:
        getReport in interface Drawing
        Parameters:
        plan - drawing plan, from calculatePlan
        Returns:
        information generated by the plot, or null
