Parameters

service	The service to connect to
persistent	Whether to keep this connection alive for more than one service call
request_md5sum	The md5sum of the request message
response_md5sum	The md5sum of the response message

lookupService()

bool ros::ServiceManager::lookupService	(	const std::string &	name,
		std::string &	serv_host,
		uint32_t &	serv_port
	)

Lookup the host/port of a service.

Parameters

name	The name of the service
serv_host	OUT – The host of the service
serv_port	OUT – The port of the service

lookupServicePublication()

ServicePublicationPtr ros::ServiceManager::lookupServicePublication

(

const std::string &

service

)

Lookup an advertised service.

This method iterates over advertised_services, looking for one with name matching the given topic name. The advertised_services_mutex is locked during this search. This method is only used internally.

Parameters

service

The service name to look for.

Returns

Pointer to the matching ServicePublication, NULL if none is found.

removeServiceServerLink()

void ros::ServiceManager::removeServiceServerLink

(

const ServiceServerLinkPtr &

client

)

Remove the specified service client from our list.

Parameters

client

The client to remove

unadvertiseService()

bool ros::ServiceManager::unadvertiseService

(

const std::string &

serv_name

)

Unadvertise a service.

This call unadvertises a service, which must have been previously advertised, using advertiseService().

After this call completes, it is guaranteed that no further callbacks will be invoked for this service.

This method can be safely called from within a service callback.

Parameters

serv_name

The service to be unadvertised.

Returns

true on successful unadvertisement, false otherwise.
