Subject [jira] Updated: (DERBY-2416) Provide a shell for a subclass of SQLChar and SQLVarch which will use the passed Collator to do the collation rather than the default collation of UCS_BASIC

Mamta A. Satoor updated DERBY-2416:
-----------------------------------

    Attachment: DERBY2416_CollationSensitiverShells_stat_v2.txt
                DERBY2416_CollationSensitiverShells_diff_v2.txt

With patch DERBY2416_CollationSensitiverShells_diff_v2.txt, I am extending the patch attached
yesterday (DERBY2416_CollationSensitiveVarcharShell_diff_v1.txt). This latest patch has collation
sensitive subclasses for SQLVarchar, SQLLongvarchar and SLQClob. The collation sensitive subclass
for SQLChar is already checked in as CollatorSQLChar. 

So, In brief, the change description for yesterday's patch applies to the patch I am attaching
right now. In addition, it applies the same logic for creating subclasses for SQLVarchar,
SQLLongvarchar and SLQClob.

These classes are not hooked into Derby runtime yet and hence won't impact the existing tests.
 

I will go ahead and commit this patch, so I can make more progress on language based ordering
task. If anyone has any comments on this patch, please let me know about them and I can address
them in subsequent patches.

> The existing SQLChar datatype has the Derby's default collation which is UCS_BASIC defined
on them. With Derby 10.3, we want to support an additional collation for char datatypes which
will be based on the territory. This jira issue is the placeholder for creating subclass of
SQLChar which will use the passed Collator to do the collation. The current use of this class
in Derby 10.3 will be for territory based collation but this class can be used in future for
other kinds of collations like case-insensitive etc.
