Constructor & Destructor Documentation

ServiceDiscovery() [1/2]

rtctk::componentFramework::ServiceDiscovery::ServiceDiscovery ( std::unique_ptr< ServiceRegistryIf > && adapter, const std::string & comp_name = "" )

explicit

Create a new ServiceDiscovery object.

Parameters

[in]	adapter	A unique_ptr to the Service Registry to use for service discovery.
[in]	comp_name	Optional: the component name if used from within an RTC component.

ServiceDiscovery() [2/2]

rtctk::componentFramework::ServiceDiscovery::ServiceDiscovery ( const elt::mal::Uri & registry, const std::string & comp_name = "" )

explicit

Create a new ServiceDiscovery object.

Parameters

[in]	registry	URI to the Service Registry, currently only file:// and consul URIs are supported.
[in]	comp_name	Optional: the component name if used from within an RTC component.

Member Function Documentation

GetOldbEndpoint()

ServiceDiscovery::ServiceEndpoint rtctk::componentFramework::ServiceDiscovery::GetOldbEndpoint

(

)

Get the Oldb Endpoint from the ServiceDiscovery.

GetPersistentRepoEndpoint()

ServiceDiscovery::ServiceEndpoint rtctk::componentFramework::ServiceDiscovery::GetPersistentRepoEndpoint

(

)

Get the Persistent Repository Endpoint from the ServiceDiscovery.

GetPubSubEndpoint()

ServiceDiscovery::ServiceEndpoint rtctk::componentFramework::ServiceDiscovery::GetPubSubEndpoint	(	const std::string &	component_name = "",
		const std::string &	service_type = ServiceRegistryIf::COMPONENT_TYPE,
		const bool	health_check = true )

Get the PubSub Endpoint of a component.

Parameters

[in]	component_name	Optional: instance (component) name, otherwise component name during construction is used.
	service_type	type of service e.g. rtctk_component
[in]	health_check	Optional: if should be checked for the health of the component before returning a valid endpoint

GetReqRepEndpoint()

ServiceDiscovery::ServiceEndpoint rtctk::componentFramework::ServiceDiscovery::GetReqRepEndpoint	(	const std::string &	name = "",
		const std::string &	service_type = ServiceRegistryIf::COMPONENT_TYPE,
		const bool	health_check = true )

Get the Request/Reply Endpoint of a service like component.

Parameters

[in]	name	Optional: instance (component) name, otherwise component name during construction is used.
	service_type	type of service e.g. rtctk_component
[in]	health_check	Optional: if should be checked for the health of the service (component) before returning a valid endpoint

GetRuntimeRepoEndpoint()

ServiceDiscovery::ServiceEndpoint rtctk::componentFramework::ServiceDiscovery::GetRuntimeRepoEndpoint

(

)

Get the Runtime Repository Endpoint from the ServiceDiscovery.

GetTelegrafEndpoint()

ServiceDiscovery::ServiceEndpoint rtctk::componentFramework::ServiceDiscovery::GetTelegrafEndpoint

(

)

Get the Telegraf Endpoint from the ServiceDiscovery.

ListComponents()

std::vector< std::string > rtctk::componentFramework::ServiceDiscovery::ListComponents

(

const std::string &

service_type = ServiceRegistryIf::COMPONENT_TYPE

)

Get known components.

Use this method to retrieve all services of a certain type (components by default) known to the service discovery

Parameters

service_type

type of service e.g. rtctk_component, if empty all types will be considered

Returns

vector of strings containing the component names
