Detailed Description

template<class T>
class Athena::RCUUpdater< T >

Implementation of Updater for RCUSvc.

This is an implementation of the Updater interface defined in CxxUtils/ConcurrentRangeMap.h using RCUSvc.

This uses RCUObject to manage an instance of type T.

Definition at line 38 of file RCUUpdater.h.

Constructor & Destructor Documentation

RCUUpdater()

template<class T >

template<typename... Args>

Athena::RCUUpdater< T >::RCUUpdater	(	IRCUSvc &	rcusvc,
		Args &&...	args
	)

Constructor.

Parameters

rcusvc	RCU service instance.
args	Additional arguments to pass to the T constructor.

Creates a new instance of T.

Member Function Documentation

defaultContext()

template<class T >

static const Context_t& Athena::RCUUpdater< T >::defaultContext ( )

static

Return the current event context.

discard()

template<class T >

void Athena::RCUUpdater< T >::discard

(

std::unique_ptr< T >

p

)

Queue an object for later deletion.

Parameters

p	The object to delete.

The object p will be queued for deletion once a grace period has passed for all slots. In contrast to using update, this does not change the current object. It also does not mark the current slot as having completed the grace period (so this can be called by a thread running outside of a slot context).

get()

template<class T >

const T& Athena::RCUUpdater< T >::get

(

)

const

Return a reference to the current object.

quiescent()

template<class T >

void Athena::RCUUpdater< T >::quiescent

(

const Context_t &

ctx

)

Mark that an event slot is not referencing this object.

update()

template<class T >

void Athena::RCUUpdater< T >::update	(	std::unique_ptr< T >	p,
		const Context_t &	ctx
	)

Install a new object.

Parameters

p	The new object to install.
ctx	Current execution context.

The existing object should not be deleted until it can no longer be referenced by any thread.

Member Data Documentation

m_obj

template<class T >

RCUObject<T> Athena::RCUUpdater< T >::m_obj
