Detailed Description

Base class for all application components, it depends on components::Logger and components::Tracer.

Constructor & Destructor Documentation

~LoggableComponentBase()

components::LoggableComponentBase::~LoggableComponentBase ( )

overridedefault

It is a good place to stop your work here. All components dependent on the current component were destroyed. All components on which the current component depends are still alive.

Member Function Documentation

GetComponentHealth()

ComponentHealth components::LoggableComponentBase::GetComponentHealth ( ) const

inlineoverride

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

Warning

The function is called concurrently from multiple threads.

Definition at line 35 of file loggable_component_base.hpp.

OnAllComponentsAreStopping()

void components::LoggableComponentBase::OnAllComponentsAreStopping ( )

inlineoverride

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.

Definition at line 60 of file loggable_component_base.hpp.

OnAllComponentsLoaded()

void components::LoggableComponentBase::OnAllComponentsLoaded ( )

inlineoverride

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.

Definition at line 53 of file loggable_component_base.hpp.

OnLoadingCancelled()

void components::LoggableComponentBase::OnLoadingCancelled ( )

inlineoverride

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.
