Detailed Description

Forms a bond to monitor another process.

The bond::Bond class implements a bond, allowing you to monitor another process and be notified when it dies. In turn, it will be notified when you die.

Definition at line 68 of file bond.h.

Constructor & Destructor Documentation

bond::Bond::Bond	(	const std::string &	topic,
		const std::string &	id,
		boost::function< void(void)>	on_broken = `boost::function<void(void)>()`,
		boost::function< void(void)>	on_formed = `boost::function<void(void)>()`
	)

Constructs a bond, but does not connect.

Parameters

topic	The topic used to exchange the bond status messages.
id	The ID of the bond, which should match the ID used on the sister's end.
on_broken	callback that will be called when the bond is broken.
on_formed	callback that will be called when the bond is formed.

Definition at line 67 of file bond.cpp.

bond::Bond::~Bond ( )

Destructs the object, breaking the bond if it is still formed.
