Db.put

						import com.sleepycat.db.*;
						public int put(DbTxn txnid, Dbt key, Dbt data, int flags)
						throws DbException;
					

Description

The Db.put method stores key/data pairs in the database. The default behavior of the Db.put function is to enter the new key/data pair, replacing any previously existing key if duplicates are disallowed, or adding a duplicate data item if duplicates are allowed. If the database supports duplicates, the Db.put method adds the new data value at the end of the duplicate set. If the database supports sorted duplicates, the new data value is inserted at the correct sorted location.

If the operation is to be transaction-protected, the txnid parameter is a transaction handle returned from DbEnv.txn_begin; otherwise, null.
