Detailed Description

template<size_t MaxServices = 8, typename EventVariant = DefaultEvents>
class corium::BasicServiceRegistry< MaxServices, EventVariant >

Non-allocating ServiceRegistry storing service handles in a fixed stack/static array. Zero heap allocations, zero vtables/RTTI.

Template Parameters

MaxServices	Maximum number of background services allowed per registry (default 8).
EventVariant	Supported event variant type list.

Member Function Documentation

getService()

template<size_t MaxServices = 8, typename EventVariant = DefaultEvents>

template<typename ServiceType >

ServiceType * corium::BasicServiceRegistry< MaxServices, EventVariant >::getService ( ) const

inlinenoexcept

Retrieve a registered service instance by concrete type.

Template Parameters

ServiceType

Type of the background service.

Returns

Pointer to registered ServiceType instance, or nullptr if not found.

Here is the call graph for this function:

getServiceById()

template<size_t MaxServices = 8, typename EventVariant = DefaultEvents>

void * corium::BasicServiceRegistry< MaxServices, EventVariant >::getServiceById ( internal::TypeIdPtr  typeId ) const

inlinenoexcept

Retrieve a registered service instance by static type ID.

Here is the caller graph for this function:

getServiceSink()

template<size_t MaxServices = 8, typename EventVariant = DefaultEvents>

template<typename ServiceType >

EventSinkT< EventVariant > corium::BasicServiceRegistry< MaxServices, EventVariant >::getServiceSink ( ) const

inlinenoexcept

Retrieve event sink handle of a target registered service if available.

Template Parameters

ServiceType

Type of the target background service.

Returns

EventSinkT handle targeting the service's incoming queue, or empty handle if unavailable.

initialize()

template<size_t MaxServices = 8, typename EventVariant = DefaultEvents>

void corium::BasicServiceRegistry< MaxServices, EventVariant >::initialize ( ServiceContextType  ctx )

inline

Initialize and launch all registered background service jthreads.

Here is the call graph for this function:

registerService()

template<size_t MaxServices = 8, typename EventVariant = DefaultEvents>

template<typename ServiceType >

bool corium::BasicServiceRegistry< MaxServices, EventVariant >::registerService ( ServiceType &  serviceInstance )

inline

Register a background service instance by reference.

Template Parameters

ServiceType

Type of the background service.

Parameters

serviceInstance

Reference to service instance.

Returns

true if service was registered successfully; false if registry is full.

shutdown()

template<size_t MaxServices = 8, typename EventVariant = DefaultEvents>

void corium::BasicServiceRegistry< MaxServices, EventVariant >::shutdown ( )

inlinenoexcept

Stop and join all registered background service threads.

size()
