common.hpp File Reference

Classes
class	flow::Function< Result(Args...)>
	Intended as the polymorphic function wrapper of choice for Flow, internally and externally; to be used instead of std::function or boost::function. More...

Namespaces
namespace	flow
	Catch-all namespace for the Flow project: A collection of various production-quality modules written in modern C++17, originally by ygoldfel.

Macros
#define	FLOW_OS_LINUX
	Macro that is defined if and only if the compiling environment is Linux.
#define	FLOW_OS_MAC
	Macro that is defined if and only if the compiling environment is Mac OS X or higher macOS (not iOS and such!).
#define	FLOW_OS_WIN
	Macro that is defined if and only if the compiling environment is Windows.

Typedefs
using	flow::uint8_t = unsigned char
	Byte. Best way to represent a byte of binary data. This is 8 bits on all modern systems.
using	flow::int8_t = signed char
	Signed byte. Prefer to use uint8_t when representing binary data. This is 8 bits on all modern systems.
using	flow::Fine_clock = boost::chrono::high_resolution_clock
	Clock used for delicate time measurements, such that the now() method gets the current time relative to some unknown but constant epoch (reference point). More...
using	flow::Fine_time_pt = Fine_clock::time_point
	A high-res time point as returned by Fine_clock::now() and suitable for precise time math in general.
using	flow::Fine_duration = Fine_clock::duration
	A high-res time duration as computed from two Fine_time_pts.
using	flow::Error_code = boost::system::error_code
	Short-hand for a boost.system error code (which basically encapsulates an integer/enum error code and a pointer through which to obtain a statically stored message string); this is how Flow modules report errors to the user; and we humbly recommended all C++ code use the same techniques. More...

Enumerations
enum class	flow::Flow_log_component { flow::S_END_SENTINEL }
	The flow::log::Component payload enumeration comprising various log components used by Flow's own internal logging. More...

Variables
const boost::unordered_multimap< Flow_log_component, std::string >	flow::S_FLOW_LOG_COMPONENT_NAME_MAP
	The map generated by flow::log macro magic that maps each enumerated value in flow::Flow_log_component to its string representation as used in log output and verbosity config. More...
