    import com.sleepycat.db.*;

    public void set_lorder(int lorder)
        throws DbException;

# Description

Set the byte order for integers in the stored database metadata. The number should represent the order as an integer; for example, big endian order is the value 4,321, and little endian order is the value 1,234. If lorder is not explicitly set, the host order of the machine where the Berkeley DB library was compiled is used.

The value of lorder is ignored except when databases are being created. If a database already exists, the byte order it uses is determined when the database is opened.

The access methods provide no guarantees about the byte ordering of the application data stored in the database, and applications are responsible for maintaining any necessary ordering.

The Db.set_lorder interface may be used only to configure Berkeley DB before the Db.open interface is called.

The Db.set_lorder method throws an exception that encapsulates a non-zero error value on failure.

# Errors

The Db.set_lorder method may fail and throw an exception encapsulating a non-zero error for the following conditions:

EINVAL
  An invalid flag value or parameter was specified.

  Called after Db.open was called.

The Db.set_lorder method may fail and throw an exception for errors specified for other Berkeley DB and C library or system methods. If a catastrophic error has occurred, the Db.set_lorder method may fail and throw a DbRunRecoveryException, in which case all subsequent Berkeley DB calls will fail in the same way.
