ObjStore Rm+O ObjectStore OODBMS Interface JPRIT
Interface to ObjectStore OODBMS (
http://www.odi.com). Stores scalars,
sets, hashes, and references directly in the database without
flattening nested or circular structures. Databases can be accessed
from Perl, C++, or Java. Designed for easy extension of the internal
data representation or data types of built-in data structures. Uses
the virtual memory mechanism to make read/write access nearly as fast
as memory mapped files.

### FUTURE PLANS ###
Preliminary design of Verity full text indexing interface below. Should
the index membership be kept in each member or not? Leaning towards
'no'.
$Txt->index($indexHandle, $userPointer)
$indexHandle - the specific Verity index object
$userPointer - returned together with the match score after a search
This can be called multiple times for different indexes. The OSSV
will
keep track of the indexes to which it has been added?
$Txt->reindex; # called if string is changed
$Txt->unindex([$indexHandle]); # called upon destruction
### RECENT CHANGES ###
** 08-11-97 Released 1.10
- Overloaded the '""' (stringify) operator for persistent objects.
- ospeek [-addr]
- Important typemap fixes plus other minor stuff.
** 08-06-97 Released 1.09
- At our site we are now using osperl for about 2GB worth of data!
- Now built to a shared library!! Anyone up for
Apache/Perl/ObjectStore?
- New, Improved Documentation.
- Persistent blessings now fully tested and working.
- ObjectStore transactions and exceptions now fully integrated into
Perl. Cursors have been removed from persistent data; read_only
transactions now properly supported. Read_only transactions are
blazingly fast!
- Regularized allocators. Specify cardinality when creating containers.
new ObjStore::$type($near, $card); Customize representation selector.
- Regularized peristent typing in preparation for extensibility.
- Peek rewrite with ideas from Data::Dumper. Peek on circular data
structures. Peek reports percent utilization to the delight of the
accountants everywhere.
- Unions removed from the schema. This major fix makes it possible to
evolve databases in the event of future schema enhancements.
- Reference counts are now 32bits wide and check for overflow.
- Static functions (e.g. ObjStore::Segment::of) are now called with ::
instead of -> for greater efficiency.
- Plus hundreds of fixes...
