db_map_iterator(const db_map_iterator< kdt, ddt,
    value_type_sub > &vi)

Copy constructor.

The other iterator of the same type to initialize this.

db_map_iterator(const db_map_base_iterator< kdt, realddt,
    ddt > &vi)

Base copy constructor.

Initialize from a base class iterator.

db_map_iterator(db_container *powner, u_int32_t b_bulk_retrieval=0,
    bool brmw=false, bool directdbget=true,
    bool b_read_only=false)

Constructor.

The bulk read buffer size. 0 means bulk read disabled.

Whether set DB_RMW flag in underlying cursor.

The container which creates this iterator.

Whether do direct database get rather than using key/data values cached in the iterator whenever read.

Whether open a read only cursor. Only effective when using Berkeley DB Concurrent Data Store.

db_map_iterator()

Default constructor, dose not create the cursor for now.

Do not create iterators directly using these constructors, but call db_map::begin or db_multimap_begin to get instances of this class.
