The values will appear in ascending order by default. Reversing the order of a collection can be made by calling reverseOrderOf. All these methods modify the underlying collection, so any indexes should always be regenerated. </P></DIV><DIVCLASS="REFSECT1"><ANAME="AEN16285"></A><H2>Protocols adopted by QSort</H2><P> <AHREF="swarm.objectbase.swarmobject.protocol.html">SwarmObject</A> <AHREF="swarm.defobj.creatable.protocol.html">CREATABLE</A></P></DIV><DIVCLASS="REFSECT1"><ANAME="AEN16290"></A><H2>Methods</H2><DIVCLASS="REFSECT2"><ANAME="AEN16292"></A><H3>Phase: Using</H3><P></P><UL><LI><DIVCLASS="FUNCSYNOPSIS"><ANAME="SWARM.SIMTOOLS.QSORT.METHOD.PU.M73"></A><P></P>+ (void)<BCLASS="FUNCPROTOTYPE">sortObjectsIn:</B> <VARCLASS="PDPARAM">aCollection</VAR> <BR> The sortObjectsIn: method will sort the objects in the collection with the "compare' function for the object.
