public class DbMultipleKeyDataIterator
extends com.sleepycat.db.DbMultipleIterator

The DbMultipleKeyDataIterator class is used to iterate through data returned using the `Db.DB_MULTIPLE_KEY` flag from a database belonging to the Btree or Hash access methods.

Constructor Summary
`DbMultipleKeyDataIterator(Dbt dbt)` The constructor takes the data `Dbt` returned by the call to `Db.get` or `Dbc.get` that used the `Db.DB_MULTIPLE_KEY` flag.

Method Summary
`boolean` `next(Dbt key, Dbt data)` The DbMultipleKeyDataIterator.next method takes two `Dbt`s, one for a key and one for a data item, that will each be filled in with a reference to a buffer, a size, and an offset that together yield the next key and data item in the original bulk retrieval buffer.

Constructor Detail

### DbMultipleKeyDataIterator

    public DbMultipleKeyDataIterator(Dbt dbt)

  The constructor takes the data `Dbt` returned by the call to `Db.get` or `Dbc.get` that used the `Db.DB_MULTIPLE_KEY` flag.

Parameters:
  `dbt` - a data `Dbt` returned by the call to `Db.get` or `Dbc.get` that used the `Db.DB_MULTIPLE_KEY` flag.

Method Detail

### next

    public boolean next(Dbt key,
                        Dbt data)

  The DbMultipleKeyDataIterator.next method takes two `Dbt`s, one for a key and one for a data item, that will each be filled in with a reference to a buffer, a size, and an offset that together yield the next key and data item in the original bulk retrieval buffer. The DbMultipleKeyDataIterator.next method returns false if no more data are available, and true otherwise.

  Parameters:
    `key` - The key parameter will be filled in with a reference to a buffer, a size, and an offset that yields the next key item in the original bulk retrieval buffer.
    `data` - The data parameter will be filled in with a reference to a buffer, a size, and an offset that yields the next data item in the original bulk retrieval buffer.
  Returns:
    The DbMultipleKeyDataIterator.next method returns false if no more data are available, and true otherwise.
