Detailed Description

template<class ServiceDataType>
class object_manipulator::MultiArmServiceWrapper< ServiceDataType >

A wrapper for multiple instances of a given service, one for each arm in the system.

This function performs mapping from an arm_name to a service for that arm.

It obtains the name of the service by adding a prefix and/or suffix to the name of the arm.

For each arm, it also performs "wait on first use service". When the service for a given arm name is first requested, it will wait for the service, then create the client and return it. It will also remember the client, so that on subsequent calls the client is returned directly without additional waiting.

Member Function Documentation

template<class ServiceDataType>

ros::ServiceClient& object_manipulator::MultiArmServiceWrapper< ServiceDataType >::client	(	std::string	arm_name,
		ros::Duration	timeout = `ros::Duration(5.0)`
	)		`[inline]`

Returns a service client for the requested arm.

Service name is obtained as prefix + arm_name + suffix. On first request for a given arm, a service client will be initialized, and the service will be waited for. On subsequent calls for the same arm, the service is returned directly.
