<H2>DESCRIPTION</H2><PRE>
|
|
The DB library is a family of classes that provides a
|
|
modular programming interface to transactions and record-
|
|
oriented file access. The library includes support for
|
|
transactions, locking, logging and file page caching, as
|
|
well as various indexed access methods. Many of the
|
|
classes (e.g., the file page caching class) are useful
|
|
independent of the other DB classes, although some classes
|
|
are explicitly based on other classes (e.g., transactions
|
|
and logging). For a general description of the DB
|
|
package, see <B><A HREF="db_intro.html">db_intro(3)</A></B>.
|
|
|
|
This manual page describes the DbLsn class.
|
|
|
|
A DbLsn is a "log sequence number" that is fully
|
|
encapsulated. The class itself has no methods, other than
|
|
a default constructor, so there is no way for the user to
|
|
manipulate its data directly. It is initialized and used
|
|
by methods in <B><A HREF="DbLog.j.html">DbLog(3)</A></B> and <B><A HREF="DbMpool.j.html">DbMpool(3)</A></B>.
