Since the class is mutable and exposes its fields publicly, we cannot cache the hashCode!

 2013-08-11 12:45:26 -07:00
Laurent FABRE 36470b61e9 The comparison method used in PointOrderStrategy#compare(Coord3d, Coord3d) 
violates the comparison contract used by the new collection sorting algorithm
of JDK/JRE7 (TimSort).

Writing:
        if (d1<d2)
            return 1;
        else
            return -1;
violates the reflexivity condition required by the new algorithm,
because it implies that A > B AND B > A are true at the same time for a
certain set of inputs A and B (in fact for all A and B such as A = B).
The condition A > B if, and only if B < A is not satisfied.
The reason is that two equal objects are not recognized as being equal
by the previous implementation of PointOrderingStrategy#compare.

Up to JDK/JRE6, the default algorithm used for sorting collection (MergeSort)
does not care about the reflexivity condition and sort the collection given
as input without throwing an error, however the new TimSort algorithm throws
an exception when it finds that the Comparator<T> provided to sort the collection
violates the reflexivity condition.

    java.lang.IllegalArgumentException: Comparison method violates its general contract!

    java.util.TimSort.mergeHi(TimSort.java:868)
    java.util.TimSort.mergeAt(TimSort.java:485)
    java.util.TimSort.mergeForceCollapse(TimSort.java:426)
    java.util.TimSort.sort(TimSort.java:223)
    java.util.TimSort.sort(TimSort.java:173)
    java.util.Arrays.sort(Arrays.java:659)
    java.util.Collections.sort(Collections.java:217)
    org.jzy3d.plot3d.rendering.ordering.AbstractOrderingStrategy.sort(AbstractOrderingStrategy.java:25)
    org.jzy3d.plot3d.rendering.scene.Graph.draw(Graph.java:182)
    org.jzy3d.plot3d.rendering.scene.Graph.draw(Graph.java:160)

It is possible to make JDK/JRE7 use the old algorithm by specifying the
following JVM option when starting the program:
    -Djava.util.Arrays.useLegacyMergeSort=true

However it looks safer and more portable to adapt the comparator so it does
not violate the contract, like in the follwing:
            if (d1<d2)
                return 1;
            else if (d2>d1)
                return -1;
            else
                return 0;

The behavior should be the same, without throwing exceptions when run
on JDK/JRE7.

I added a test org.jzy3d.tests.TestPointOrderingStrategy#testPointOrdering
that fails with previous sorting implementation on JDK/JRE7 without the
-Djava.util.Arrays.useLegacyMergeSort=true options. The test is successfull
with the new implementation of PointOrderStrategy#compare(Coord3d, Coord3d)
on both JDK/JRE6 and 7.

cmh b38e2b160b first refactoring pass : 
- distinct draw path for Open GL ES
- use newt events as primary event types
- partial AWT classes removal

Mouse event are partially broken : click are ok, drags are lost in a
simple AWT Canvas test. Next step is development of a working Android
subset.
