Static Public Member Functions
void	copy (unsigned const char *from, unsigned char *dest, const int size, const int count)
	Copies the the data in XDR, i.e.
template<class T> void	tostream (std::string &s, T *t, unsigned count)
	Writes count objects of (simple) type T to the string s in Xdr format.
template<class T> unsigned	fromstream (const std::string &s, unsigned position, T *t, unsigned count)
	Read count objects of (simple) type t from the string/stream s at position. Callers have to keep the current position within the string.
void	tostream (std::string &s, std::string *strVal, unsigned count)
	Specialization for strings - count is ignored and taken to be 1.
unsigned	fromstream (const std::string &s, unsigned index, std::string *strVal, unsigned count)
	Specialization for strings - count is ignored and taken to be 1.

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.

Member Function Documentation

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

unsigned lccd::Xdr::fromstream (  const std::string &  s, unsigned  index, std::string *  strVal, unsigned  count )  [inline, static]

Specialization for strings - count is ignored and taken to be 1. Returns: the new position in the stream.

template<class T> unsigned lccd::Xdr::fromstream (  const std::string &  s, unsigned  position, T *  t, unsigned  count )  [inline, static]

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.
