Member Function Documentation

FillRequestWithTracingContext()

virtual void tracing::TracingManagerBase::FillRequestWithTracingContext ( const Span & span, clients::http::PluginRequest request ) const

pure virtualinherited

Fill new client requests with tracing information.

Implemented in tracing::GenericTracingManager.

FillResponseWithTracingContext()

virtual void tracing::TracingManagerBase::FillResponseWithTracingContext ( const Span & span, server::http::HttpResponse & response ) const

pure virtualinherited

Fill response with tracing information.

Implemented in tracing::GenericTracingManager.

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.

GetStaticConfigSchema()

static yaml_config::Schema components::ComponentBase::GetStaticConfigSchema ( )

staticinherited

If the component pulls more options from ComponentConfig than its parent component, then it needs to define GetStaticConfigSchema method and add its own options to the parent component's options.

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.

Definition at line 42 of file component_base.hpp.

TryFillSpanBuilderFromRequest()

virtual bool tracing::TracingManagerBase::TryFillSpanBuilderFromRequest ( const server::http::HttpRequest & request, SpanBuilder & span_builder ) const

pure virtualinherited

Fill SpanBuilder params with actual tracing information extracted from the request. You should build Span with SpanBuilder::Build, after calling this.

Returns

Returns bool, that tells us was any of tracing headers used to create new span

Implemented in tracing::GenericTracingManager.
