CreateMiddleware()

template<typename MiddlewareBaseType , typename HandlerInfo >

virtual std::shared_ptr< MiddlewareBase > middlewares::MiddlewareFactoryComponentBase< MiddlewareBaseType, HandlerInfo >::CreateMiddleware ( const HandlerInfo & info, const yaml_config::YamlConfig & middleware_config ) const

pure virtual

Returns a middleware according to the component's settings.

Parameters

info	is a handler info for the middleware.
middleware_config	config for the middleware.

Warning

Don't store info by reference. info object will be dropped after the CreateMiddleware call.

GetComponentHealth()

ComponentHealth components::ComponentBase::GetComponentHealth ( ) const

inlineoverridevirtualinherited

Override this function to inform the world of the state of your component.

Warning

The function is called concurrently from multiple threads.

Reimplemented from components::RawComponentBase.

Reimplemented in server::handlers::Restart.

Definition at line 35 of file component_base.hpp.

GetMiddlewareConfigSchema()

template<typename MiddlewareBaseType , typename HandlerInfo >

virtual yaml_config::Schema middlewares::MiddlewareFactoryComponentBase< MiddlewareBaseType, HandlerInfo >::GetMiddlewareConfigSchema ( ) const

inlinevirtual

This method should return the schema of a middleware configuration. Always write return GetStaticConfigSchema(); in this method.

Reimplemented in ugrpc::client::middlewares::log::Component, ugrpc::server::middlewares::headers_propagator::Component, and ugrpc::server::middlewares::log::Component.

Definition at line 76 of file runner.hpp.

GetStaticConfigSchema()

OnAllComponentsAreStopping()

void components::ComponentBase::OnAllComponentsAreStopping ( )

inlineoverridevirtualinherited

Component may use this function to stop doing work before the stop of the components that depend on it.

Base components may override it and make final to do some work before the derived object constructor is called. Don't use it otherwise.

Reimplemented from components::RawComponentBase.

Reimplemented in urabbitmq::ConsumerComponentBase, and components::Server.

Definition at line 58 of file component_base.hpp.

OnAllComponentsLoaded()

void components::ComponentBase::OnAllComponentsLoaded ( )

inlineoverridevirtualinherited

Component may use this function to finalize registration of other components that depend on it (for example, handler components register in server component, and the latter uses OnAllComponentsLoaded() to start processing requests).

Base components may override it and make final to do some work after the derived object constructor is called. Don't use it otherwise.

Reimplemented from components::RawComponentBase.

Reimplemented in urabbitmq::ConsumerComponentBase, components::Server, and server::handlers::Ping.

Definition at line 51 of file component_base.hpp.

OnLoadingCancelled()

void components::ComponentBase::OnLoadingCancelled ( )

inlineoverridevirtualinherited

Called once if the creation of any other component failed. If the current component expects some other component to take any action with the current component, this call is a signal that such action may never happen due to components loading was cancelled. Application components might not want to override it.

Reimplemented from components::RawComponentBase.
