# Db.get_type

    import com.sleepycat.db.*;

    public int get_type();

# Description

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 be called only after the Db.open interface has been called.

# Errors

The Db.get_type 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 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.
