Classes
class	madara::transport::FragmentMessageHeader
	Defines a fragmentation header which allows for multi-part messages that are only applied once all fragments are received. More...

	madara::transport
	Provides the network transport layer for knowledge bases to communicate within and across agents.

Typedefs
typedef std::map< uint64_t, FragmentMap >	madara::transport::ClockFragmentMap
	Map of clocks to fragments. More...
typedef std::map< uint32_t, const char * >	madara::transport::FragmentMap
	Map of fragment identifiers to fragments. More...

Functions
MADARA_EXPORT char *	madara::transport::add_fragment (const char *originator, uint64_t clock, uint32_t update_number, const char *fragment, uint32_t queue_length, OriginatorFragmentMap &map, bool clear=true)

MADARA_EXPORT void	madara::transport::delete_fragments (FragmentMap &map)
	Deletes fragments within a fragment map and clears the map. More...
MADARA_EXPORT bool	madara::transport::exists (const char *originator, uint64_t clock, uint32_t update_number, OriginatorFragmentMap &map)
	Checks if a fragment already exists within a fragment map. More...
MADARA_EXPORT void	madara::transport::frag (const char *source, uint32_t fragment_size, FragmentMap &map)
	Breaks a large packet into smaller packets. More...
MADARA_EXPORT bool	madara::transport::is_complete (const char *originator, uint64_t clock, OriginatorFragmentMap &map)
	Breaks a large packet into smaller packets. More...
