# Db.set_re_len |

`

###

    import com.sleepycat.db.*;

    public void set_re_len(int re_len)
    	throws DbException;

# Description

For the Queue access method, specify that the records are of length re_len.

For the Recno access method, specify that the records are fixed-length, not byte delimited, and are of length re_len.

Any records added to the database that are less than re_len bytes long are automatically padded (see Db.set_re_pad for more information).

Any attempt to insert records into the database that are greater than re_len bytes long will cause the call to fail immediately and return an error.

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

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

# Errors

EINVAL
  An invalid flag value or parameter was specified.

  Called after Db.open was called.
