Detailed Description

---

Class representing a feature flag

Modules can use this class to define flags they are interested in. Data provided by module includes

1. Flag name
2. Description
3. Context Info (optional)
4. Callback for run-time updates (optional) The Flag class will in turn register this Flag with the Flag Manager.

Constructor & Destructor Documentation

process::Flag::Flag	(	FlagManager *	manager,
		const std::string &	name,
		const std::string &	description,
		bool	enabled,
		ContextVec &	context_infos
	)

This constructor is used to create a feature flag with basic information; name, description, default behavior and optional context information.

process::Flag::Flag	(	const Flag &	flag,
		FlagStateCb	callback
	)

This constructor takes a Flag object with basic information with provision for components to act on run-time updates through a callback
