Detailed Description

Deprecated:

Classes RWDBBinaryVector and RWDBBinaryVectorElement are deprecated. Please use classes RWDBBlob and RWDBTBuffer<RWDBBlob>.

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);

Examples

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
