tcspc::access_tracker< Access > Class Template Reference

Description

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

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 access 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

Access

type of access interface for the tracked object

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

Constructor & Destructor Documentation

access_tracker()

template<typename Access>

tcspc::access_tracker< Access >::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_access_factory()

template<typename Access>

template<typename F>

void tcspc::access_tracker< Access >::register_access_factory ( F factory )

inline

Register an access 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 access type.

Template Parameters

F	factory function type

Parameters

factory

function taking reference to this tracker and returning the access object of type Access
