public int get_type();
The Db.get_type method
returns the type of the underlying access method (and file format).
The returned value is one of Db.DB_BTREE, Db.DB_HASH,
Db.DB_RECNO, or Db.DB_QUEUE. This value may be used to
determine the type of the database after a return from Db.open
with the type argument set to Db.DB_UNKNOWN.
The Db.get_type interface may not be called before the Db.open
interface has been called.
The Db.get_type method may fail and throw an exception encapsulating a non-zero error for the following conditions:
- An invalid flag value or parameter was specified.
Called before Db.open was called.
The Db.get_type 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.get_type method may fail and
throw a DbRunRecoveryException,
in which case all subsequent Berkeley DB calls will fail in the same way.
