Collaboration diagram for Directory:

Classes
class	stapl::detail::default_key_mapper< Key >
	Define default key to location mapping strategy used in the directory class used by containers and the PARAGRAPH. More...

class	stapl::detail::non_migratable_base< Key >
	Trivial class used to unconditionally signal certainty about presence of key on a location when migration is disabled. More...

class	stapl::detail::migratable_base< Key >
	Class used by detail::directory_base to verify a key is still registered on a location when migration is enabled (it's possible key has moved while this request was in flight). More...

struct	stapl::async_transmitter
	Transmitter for Directory that sends requests using async_rmi(). More...

struct	stapl::unordered_async_transmitter
	Transmitter for Directory that sends requests using unordered::async_rmi(). More...

struct	stapl::try_transmitter
	Transmitter for Directory that sends requests with try_rmi(). More...

class	stapl::detail::directory_base< Key, Transmitter, Mapper, Registry, EnableMigration >
	Base class of Directory that provides the bulk of the non migration specific implementation. More...

class	stapl::directory< Key, Transmitter, Mapper, Registry, EnableMigration >
	Provides basic functionality to forward computation (via a generic functor) to a location determined by the distributed registration of key values. The class handles heterogeneous work requests and supports relaxed consistency, placing no synchronization requirements on the registration of key and functor forwarding requests employing that key. More...

class	stapl::directory< Key, Transmitter, Mapper, Registry, true >
	Specialization with migration support. More...

class	stapl::detail::directory_request_base< Key, IntrusiveHook >
	Abstract base representing encapsulation of a buffered directory request which must be buffered at location managing a given key, pending key registration. More...

class	stapl::detail::directory_request< Directory, Functor, IntrusiveHook >
	Derived class of directory_request_base which holds function object associated with request and also defines the pointer to member method of the directory which will be used to service this request. More...

◆ invoke_at_manager() [1/2]

template<typename Key, typename Transmitter, typename Mapper, typename Registry, bool EnableMigration>

template<typename Directory , typename... PMFArgs, typename... Args>

void stapl::detail::directory_base< Key, Transmitter, Mapper, Registry, EnableMigration >::invoke_at_manager	(	Key const &	key,
		void(Directory::*)(PMFArgs...)	pmf,
		Args &&...	args
	)

protected

Forwards functor and arguments to location managing key. The location managing the key will invoke the method with the supplied arguments.

Parameters

key	Key value whose managing location (i.e., where registry entry is stored) is where `pmf` will be invoked.
pmf	Directory member function to be invoked.
args	variadic list of arguments to be applied.

This is used to internally encapsulate to forward various method invocations from the requester (e.g., registration, invoke_where, etc) to the location where they can be serviced, forwarded, etc.
