grpc_protovalidate::client::ValidatorComponent Class Reference

#include <userver/grpc-protovalidate/client/component.hpp>

Detailed Description

Component for gRPC client response validation.

This component checks whether gRPC response satisfies constraints specified in the proto file using protovalidate syntax. If it does not, middleware throws grpc_protovalidate::client::ResponseError with information about violated constraints.

Static options:

Name	Description	Default value
fail-fast	do not check remaining constraints after first error is encountered	false
methods	array of per-method middleware options overrides	[]
methods.name	fully-qualified (with package and service) method name	-
methods.fail-fast	see fail-fast	-

CreateMiddleware() [1/2]

std::shared_ptr< const ugrpc::client::MiddlewareBase > grpc_protovalidate::client::ValidatorComponent::CreateMiddleware ( const ugrpc::client::ClientInfo & , const yaml_config::YamlConfig & middleware_config ) const

override

Definition at line 35 of file component.cpp.

CreateMiddleware() [2/2]

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

pure virtualinherited

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() [1/2]

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.

GetComponentHealth() [2/2]

ComponentHealth components::ComponentBase::GetComponentHealth ( ) const

inlineoverrideinherited

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

Warning

The function is called concurrently from multiple threads.

GetMiddlewareConfigSchema()

yaml_config::Schema grpc_protovalidate::client::ValidatorComponent::GetMiddlewareConfigSchema ( ) const

overridevirtual

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

Reimplemented from middlewares::MiddlewareFactoryComponentBase< MiddlewareBase, ClientInfo >.

OnAllComponentsAreStopping() [1/2]

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 components::Server, and urabbitmq::ConsumerComponentBase.

Definition at line 58 of file component_base.hpp.

OnAllComponentsAreStopping() [2/2]

void components::ComponentBase::OnAllComponentsAreStopping ( )

inlineoverrideinherited

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 58 of file component_base.hpp.

OnAllComponentsLoaded() [1/2]

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

Definition at line 51 of file component_base.hpp.

OnAllComponentsLoaded() [2/2]

void components::ComponentBase::OnAllComponentsLoaded ( )

inlineoverrideinherited

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 51 of file component_base.hpp.

OnLoadingCancelled() [1/2]

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.

OnLoadingCancelled() [2/2]

void components::ComponentBase::OnLoadingCancelled ( )

inlineoverrideinherited

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.
