Compares two instances of TransitionTarget in terms of the
SCXML tree hierarchy.
Important Remarks:
does not fullfill the Comparator contract,
since it returns 0 if o1 == o2 and also if they are not related to each
other and at the same time the chain-to-parent length for o1 is the
same length as for o2 (that is, they are equally deeply nested)
Parameters: o1 - The first TransitionTarget object Parameters: o2 - The second TransitionTarget object int The comparation result See Also:java.util.Comparator.compare(java.lang.Objectjava.lang.Object) See Also:TransitionTarget
