Contains functions which allow you to query information about the master.
Check whether the master is up.
This method tries to contact the master. You can call it any time after ros::init has been called. The intended usage is to check whether the master is up before trying to make other requests (subscriptions, advertisements, etc.).
|bool ros::master::execute||(||const std::string &||method,|
|const XmlRpc::XmlRpcValue &||request,|
Execute an XMLRPC call on the master.
|method||The RPC method to invoke|
|request||The arguments to the RPC call|
|response||[out] The resonse that was received.|
|payload||[out] The payload that was received.|
|wait_for_master||Whether or not this call should loop until it can contact the master|
|const std::string & ros::master::getHost||(||)|
|bool ros::master::getTopics||(||V_TopicInfo &||topics||)|
Get the list of topics that are being published by all nodes.
This method communicates with the master to retrieve the list of all currently advertised topics.
|topics||A place to store the resulting list. Each item in the list is a pair <string topic, string type>. The type is represented in the format "package_name/MessageName", and is also retrievable through message.__getDataType() or MessageName::__s_getDataType().|
