## db_vector

### Function Details

    db_vector(Db *dbp=NULL,
        DbEnv *penv=NULL)

Constructor.

Note that we do not need an allocator in db-stl containser, but we need backing up Db* and DbEnv*, and we have to verify that the passed in bdb handles are valid for use by the container class. See class detail for handle requirement.

#### Parameters

##### dbp

The same as that of db_container(Db*, DbEnv*) ;

##### penv

The same as that of db_container(Db*, DbEnv*) ;

#### See Also

db_container(Db*, DbEnv*) ;

    db_vector(size_type n, const T &val=T(), Db *dbp=NULL,
        DbEnv *penv=NULL)

Constructor.

This function supports auto-commit. Insert n elements of T type into the database, the value of the elements is the default value or user set value. See class detail for handle requirement.

#### Parameters

##### dbp

The same as that of db_container(Db*, DbEnv*) ;

##### penv

The same as that of db_container(Db*, DbEnv*) ;

##### val

The value of elements to insert.

##### n

The number of elements to insert.

Copy constructor.

This function supports auto-commit. Insert all elements in x into this container.

    db_vector(Db *dbp, DbEnv *penv, InputIterator first,
        InputIterator last)

Insert a range of elements into this container.

The range is [first, last), which contains elements that can be converted to type T automatically. See class detail for handle requirement.

#### Parameters

##### dbp

The same as that of db_container(Db*, DbEnv*) ;

##### first

Range closed boundary.

##### last

Range open boundary.

##### penv

The same as that of db_container(Db*, DbEnv*) ;

db_vector(Db*, DbEnv*) ;

    db_vector(const_iterator first, const_iterator last, Db *dbp=NULL,
        DbEnv *penv=NULL)

Range constructor.

This function supports auto-commit. Insert the range of elements in [first, last) into this container. See class detail for handle requirement.

#### Parameters

##### dbp

The same as that of db_container(Db*, DbEnv*) ;

##### first

Range closed boundary.
