Typedefs
using	vg::io::message_consumer_function_t = function< void(const string &)>
	This is the type of a function that can be fed a series of messages. More...
using	vg::io::message_sender_function_t = function< void(const message_consumer_function_t &)>
	This is the type of a function that can be given a message consumer to feed messages to. More...
using	vg::io::load_function_t = function< void *(const message_sender_function_t &)>
	This is the type of a function that can allocate and load an object of unspecified type from a message source. More...
using	vg::io::save_function_t = function< void(const void *, const message_consumer_function_t &)>
	This is the type of a function that can serialize an object of unspecified type to a message consumer. More...
using	vg::io::bare_load_function_t = function< void *(istream &)>
	This is the type of a function that can load an object of unspecified type from a bare input stream. More...
using	vg::io::bare_load_function_with_filename_t = function< void *(istream &, const string &)>
	Like above, but keep track of an optional (can be empty) filename (ie where stream comes from) More...
using	vg::io::bare_save_function_t = function< void(const void *, ostream &)>
	This is the type of a function that can save an object of unspecified type to a bare output stream. More...

Functions
auto	vg::io::wrap_bare_loader (function< void *(istream &)> istream_loader) -> load_function_t
void	vg::io::with_function_calling_stream (const message_consumer_function_t &emit_message, const function< void(ostream &)> &use_stream)
auto	vg::io::wrap_bare_saver (function< void(const void *, ostream &)> ostream_saver) -> save_function_t

Detailed Description

Handles bookkeeping for the various data type tags in stream files.

TO ADD A PROTOBUF TYPE:

• Add a register_protobuf<Type>("TAG") to Registry::register_everything() in registry.cpp TO ADD A NON-PROTOBUF LOADER/SAVER:
• Write your own static initialization code somewhere that will end up in your binary.
• Make it call Registry::register_loader_saver<Type[, Base[, Base[...]]]>(tag, load_function, save_function)
