Convenience wrapper that can be used for small chunks of data when you can provide a large enough buffer. The default implementation creates an
scursor and extending to send into the buffer described by dcursor and dend .This function doesn't support chaining of blocks. The returned block cannot be added to, but you don't need to finalize it, too.
Example usage ( KMime::Codec * codec = KMime::Codec::codecForName( "base64" ); kdFatal( !codec ) << "no base64 codec found!?" << endl; QByteArray out( in.size()*1.4 ); // crude maximal size of b64 encoding QByteArray::Iterator iit = in.begin(); QByteArray::Iterator oit = out.begin(); if ( !codec->encode( iit, in.end(), oit, out.end() ) ) { kdDebug() << "output buffer too small" << endl; return; } kdDebug() << "Size of encoded data: " << oit - out.begin() << endl;

Even more convenient, but also a bit slower and more memory intensive, since it allocates storage for the worst case and then shrinks the result QByteArray to the actual size again.

For use with small This method only works for codecs whose output is in the 8bit domain (ie. not in the binary domain). Codecs that do not fall into this category will return a null QCString. |
