Detailed Description

Deprecated:
As of SourcePro 6, use RWDBTBuffer<RWDBBlob> and RWDBBlob instead.

RWDBBinaryVector instances are used to transfer binary arrays of width width between the application and the database via classes RWDBBulkReader and RWDBBulkInserter.

Synopsis
#include <rw/db/dbvector.h>
RWDBBinaryVector binaryVector(width, length);
Example

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.

RWDBBinaryVector binaryVector(width, length);
.
.
.
binaryVector[i] = RWDBBlob("Hello", 5);
.
.
.
RWDBBinaryVectorElement element = binaryVector[i];
// print the contents of the element
cout << "length of element is: " << binaryVector.width(i) << endl;
cout << "the element's data is: ";
unsigned char* ptr = (unsigned char*) element;
for (size_t j = 0; j < binVector.width(i); ++j, ++ptr)
cout.put(*ptr);
cout << endl;

Program Output:

length of element is: 5
the element's data is: Hello

Constructor & Destructor Documentation

RWDBBinaryVector::RWDBBinaryVector ( size_t  width,
size_t  length 
)
inline

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

Member Function Documentation

size_t RWDBBinaryVector::length ( ) const
inline

Returns the number of elements in self.

RWDBBinaryVectorElement RWDBBinaryVector::operator[] ( size_t  i)
inline

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