Detailed Description

Utility functions for DB streamer objects.

These functions take care of the byte ordering and make sure the streamed data adheres to the xdr convention, e.g. every data item starts at a 32-bit word boundary.

static void lccd::Xdr::copy ( unsigned const char *  from, unsigned char *  dest, const int  size, const int  count  )

static

Copies the the data in XDR, i.e.

machine independent format from one location to the another

Referenced by fromstream(), and tostream().

template<class T >

static unsigned lccd::Xdr::fromstream ( const std::string &  s, unsigned  position, T *  t, unsigned  count  )

inlinestatic

Read count objects of (simple) type t from the string/stream s at position.

Callers have to keep the current position within the string.

Returns

the new position in the stream.

inlinestatic

Specialization for strings - count is ignored and taken to be 1.

Returns

the new position in the stream.
