## rbegin

### Function Details

    reverse_iterator rbegin(ReadModifyWriteOption rmw=
        ReadModifyWriteOption::no_read_modify_write(), bool readonly=false,
        BulkRetrievalOption bulk_read=BulkRetrievalOption::no_bulk_retrieval(),
        bool directdb_get=true)

Create a reverse iterator.

This function creates a reverse iterator initialized to sit on the last element in the underlying database, and can be used to read/write. The meaning and usage of its parameters are identical to the above begin function.

#### Parameters

##### directdb_get

Same as that of begin(ReadModifyWrite, bool, BulkRetrievalOption, bool);

##### bulk_read

Same as that of begin(ReadModifyWrite, bool, BulkRetrievalOption, bool);

##### rmw

Same as that of begin(ReadModifyWrite, bool, BulkRetrievalOption, bool);

##### readonly

Same as that of begin(ReadModifyWrite, bool, BulkRetrievalOption, bool);

#### Return Value

The created iterator.

#### See Also

begin(ReadModifyWrite, bool, BulkRetrievalOption, bool);

    const_reverse_iterator rbegin(BulkRetrievalOption bulkretrieval=
        BulkRetrievalOption(BulkRetrievalOption::no_bulk_retrieval()),
        bool directdb_get=true) const

Create a const reverse iterator.

This function creates a const reverse iterator initialized to sit on the last element in the backing database, and can only read the element, it is only available to const db_vector containers. The meaning and usage of its parameters are identical as above.

#### Parameters

##### directdb_get

Same as that of begin(ReadModifyWrite, bool, BulkRetrievalOption, bool);

##### bulkretrieval

Same as that of begin(ReadModifyWrite, bool, BulkRetrievalOption, bool);

#### Return Value

The created iterator.

#### See Also

begin(ReadModifyWrite, bool, BulkRetrievalOption, bool);
