RWDBDecimalVector instances are used to transfer decimal arrays of width width
between the application and the database via instances of RWDBBulkReader and RWDBBulkInserter. Note that it is the user's responsibility to ensure that the elements of the vectors are null terminated.
In the following example, the ith
element of an RWDBDecimalVector is set to the decimal 12.567
:
|
inline |
Constructs an RWDBDecimalVector of length elements, each of whose elements is width wide.
|
inline |
Returns the number of elements in self.
|
inline |
Returns an RWDBDecimalVectorElement instance holding a reference to the i th element of self.
