[Squirrel-sql-develop] Update Feature Patch: hierachical table display ..

[Henner Z. <HZ...@me...>]

Hi,
In the former patch to this topic I replaced the ArrayList to store the
table infos with a HashSet - this was because its O(n) to remove from an
ArrayList but only O(1) from an HashSet. Unfortunatly, this destroys the
order of the tables, sine the hash function has no order ..

.. so now I implemented this with a TreeSet that orders the tables
alphabetically (for this, I made the IDatabaseObjectInfo extend Comparable
and compare the qualified names in DatabaseObjectInfo). This has the nice
side-effect, that table names are always sorted, even if JDBC-drivers
fail so return them sorted.

See attached patch. This is a patch agains current CVS.

ciao,
