public int get_type();
28
<p>The Db.get_type method
29
returns the type of the underlying access method (and file format).
30
The returned value is one of Db.DB_BTREE, Db.DB_HASH,
31
Db.DB_RECNO, or Db.DB_QUEUE. This value may be used to
32
determine the type of the database after a return from <a href="../api_java/db_open.html">Db.open</a>
33
with the <b>type</b> argument set to Db.DB_UNKNOWN.
34
<p>The Db.get_type interface may not be called before the <a href="../api_java/db_open.html">Db.open</a>
35
interface has been called.
37
<p>The Db.get_type method may fail and throw an exception encapsulating a non-zero error for the following conditions:
39
<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.
40
<p>Called before <a href="../api_java/db_open.html">Db.open</a> was called.
42
<p>The Db.get_type method may fail and throw an exception for errors specified for other Berkeley DB and C library or system methods.
43
If a catastrophic error has occurred, the Db.get_type method may fail and
44
throw a <a href="../api_java/runrec_class.html">DbRunRecoveryException</a>,
45
in which case all subsequent Berkeley DB calls will fail in the same way.
