tcspc::access_tracker< Accessor > Class Template Reference

Description

template<typename Accessor>
class tcspc::access_tracker< Accessor >

Tracker that mediates access to objects via a tcspc::context.

This is a movable (noncopyable) object that tracks its address when moved. The address is stored in the associated tcspc::context from which the tracker was created.

An object stores the tracker instance as a data member and also registers an accessor factory in its constructor. This allows code to later access the object state, even after the tracked object has been embedded in an outer object (as with a processor incorporated into a processing graph).

Template Parameters

Accessor

type of accessor for the tracked object

Public Member Functions
	access_tracker ()=default
	Construct an empty tracker.
template<typename F>
void	register_accessor_factory (F factory)
	Register an accessor factory with this tracker's context.

Constructor & Destructor Documentation

access_tracker()

template<typename Accessor>

tcspc::access_tracker< Accessor >::access_tracker ( )

default

Construct an empty tracker.

Empty instances cannot be used other than by assigning a non-empty instance.

Non-empty instances can only be obtained from a tcspc::context.

Member Function Documentation

register_accessor_factory()

template<typename Accessor>

template<typename F>

void tcspc::access_tracker< Accessor >::register_accessor_factory ( F factory )

inline

Register an accessor factory with this tracker's context.

This is usually called in the tracked object's constructor to arrange for later access to the object via its corresponding accessor type.

Template Parameters

F	factory function type

Parameters

factory

function taking reference to this tracker and returning the accessor of type Accessor
