| Call the service aliased by this handle with the specified service request/response. | |

| bool | call (MReq &req, MRes &res) |
| Call the service aliased by this handle with the specified request/response messages. | |
| bool | exists () |
| Checks if this is both advertised and available. | |
| std::string | getService () |
| Returns the name of the service this ServiceClient connects to. | |
| bool | isValid () const |
| Returns whether or not this handle is valid. For a persistent service, this becomes false when the connection has dropped. Non-persistent service handles are always valid. | |

| Shutdown the connection associated with this ServiceClient. | |

| void ros::ServiceClient::shutdown | ( | ) |
Shutdown the connection associated with this ServiceClient.
This method usually does not need to be explicitly called, as automatic shutdown happens when all copies of this ServiceClient go out of scope
This method overrides the automatic reference counted shutdown, and does so immediately.
Definition at line 166 of file service_client.cpp.
| bool ros::ServiceClient::waitForExistence | ( | ros::Duration | timeout = ros::Duration(-1) |
) |
Wait for this service to be advertised and available. Blocks until it is.
| timeout | The amount of time to wait for before timing out. If timeout is -1 (default), waits until the node is shutdown |
