RWDBStringVector stringVector(width, length);

RWDBStringVectors are used to transfer character arrays of width width between the application and the database via RWDBBulkReaders and RWDBBulkInserters. Note that it is the user's responsibility to insure that the elements of the vectors are null terminated, and so the width of each element should be set to accomodate this additional character.

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

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

RWDBStringVector(size_t width, size_t length);

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

RWDBStringVectorElement
operator[](size_t i);

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

RWBoolean
isNull(size_t index) const;

Returns true if the index^th element of self is null, otherwise returns false. Inherited from RWDBTBuffer<char>.

size_t
length() const;

Returns the number of elements in self.

void 
setNull(size_t index);

Sets the index^th element of self to null. Inherited from RWDBTBuffer<char>.

void 
unsetNull(size_t index);

Sets the index^th element of self to not null. Inherited from RWDBTBuffer<char>.

size_t
width() const;

Returns the width of the elements in self. Inherited from RWDBTBuffer<char>.
