ipc::shm::classic::stat Namespace Reference

Stats-related sub-namespace, for ADL segregation and general organization. More...

Classes
struct	Arena_info_dump
	Printable (with knobs in contained util::stat::Info_dump_format) bundling of stats/info pertaining to a particular SHM-classic Pool_arena, as stat-consumed at a particular point in time. More...
struct	Arena_stats
	Cumulative stats relevant to one SHM-classic arena – in this case single SHM-pool in shared memory, accessed via 1+ Pool_arena objects over time. More...
struct	Local_stats
	Cumulative stats relevant to a given SHM-classic arena object – a Pool_arena – and excluding those in Arena_stats which track the underlying in-SHM arena (pool) itself. More...

Functions
std::ostream &	operator<< (std::ostream &os, const Arena_info_dump &val)
	Prints string representation of the given Arena_info_dump to the given ostream. More...
template<typename Visitor >
void	declare_stats (const flow::util::stat::Stat_name &name_prefix, const Arena_stats *src_stats, Arena_stats *target_stats, Visitor &&visitor)
	Declares the stats for Arena_stats. More...

		Visitor &&	visitor
	)

Declares the stats for Arena_stats.

Not invoked directly except by flow::util::stat internals, or when composing this stat-set into another.

See also

flow::util::stat namespace doc header for background on the declare/visit mechanism.

Template Parameters

Visitor

See above.

Parameters

name_prefix	See above.
src_stats	See above.
target_stats	See above.
visitor	See above.

		const Local_stats *	src_stats,
		Local_stats *	target_stats,
		Visitor &&	visitor
	)

Declares the stats for Local_stats.

Not invoked directly except by flow::util::stat internals, or when composing this stat-set into another.

operator<<()

std::ostream & ipc::shm::classic::stat::operator<<	(	std::ostream &	os,
		const Arena_info_dump &	val
	)

Prints string representation of the given Arena_info_dump to the given ostream.

Note

val.m_fmt (util::stat::Info_dump_format) may contain knobs to affect the shape of the printed output.

Parameters

os	Stream to which to write.
val	Object to serialize.

Returns

os.
