RWDBBinaryVector instances are used to transfer binary arrays of width width
between the application and the database via classes RWDBBulkReader and RWDBBulkInserter.
In the following example, the ith
element of an RWDBBinaryVector is set to hold the data Hello
, and the data and width are output to the screen.
Program Output:
|
inline |
Constructs an RWDBBinaryVector of length elements, each of whose elements is width wide.
|
inline |
Returns the number of elements in self.
|
inline |
Returns an RWDBBinaryVectorElement holding a reference to the i th element of self.
