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

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

    Attachment: DERBY2416_NewCharClassWithDifferentCollationSupport_stat_v2.txt
                DERBY2416_NewCharClassWithDifferentCollationSupport_diff_v2.txt

I am attaching a new patch, DERBY2416_NewCharClassWithDifferentCollationSupport_diff_v2.txt
which has incorporated some of the feedback on the first patch.
1)I have renamed the new class as CollatorSQLChar
2)I have renamed intArray as collationElementsForString
3)I have renamed intLength as countOfCollationElements
4)Added javadocs for the fields and methods.
5)I have changed the javadoc for the class to talk in terms of RuleBasedCollator rather than
the interface Collator because the class is using RuleBasedCollator.

I will commit this patch in few more minutes but if anyone has any further comments on this
patch, please feel free to raise them. I can address those comments in a followup patch.

> 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.
