Detailed Description

Deprecated:

As of SourcePro 6, use RWDBTBuffer<RWCString> and RWCString instead.

RWDBStringVector instances are used to transfer character arrays of width width between the application and the database via classes RWDBBulkReader and RWDBBulkInserter. Note that it is the user's responsibility to ensure that the elements of the vectors are null terminated, and so the width of each element should be set to accommodate this additional character.

Synopsis

#include <rw/db/dbvector.h>

RWDBStringVector stringVector(width, length);

Example

In the following example, the ith element of an RWDBStringVector is set to the string "Hello";

RWDBStringVector stringVector(width, length);
.
.
.
stringVector[i] = RWCString("Hello");

Constructor & Destructor Documentation

RWDBStringVector::RWDBStringVector ( size_t  width, size_t  length  )

inline

Constructs an RWDBStringVector of length elements, each of whose elements is width wide.

Member Function Documentation

size_t RWDBStringVector::length ( ) const

inline

Returns the number of elements in self.

RWDBStringVectorElement RWDBStringVector::operator[] ( size_t  i )

inline

Returns an RWDBStringVectorElement instance holding a reference to the i ^th element of self.
