        SyncThread

A thread to synchronize the local ROS master with a remote master. While the synchronization only the topic of the remote ROS master will be registered by the local ROS master. The remote ROS master will be keep unchanged.

Instance Methods

__init__(self, name, uri, discoverer_name, monitoruri, timestamp, sync_on_demand=False)
Initialization method for the SyncThread.

source code

SyncMasterInfo

getSyncInfo(self)
Returns the synchronized publisher, subscriber and services.

source code

update(self, name, uri, discoverer_name, monitoruri, timestamp)
Sets a request to synchronize the local ROS master with this ROS master.

source code

setOwnMasterState(self, own_state, sync_on_demand=False)
Sets the state of the local ROS master state.

source code

stop(self)
Stops running thread.

Method Details

init(self, name, uri, discoverer_name, monitoruri, timestamp, sync_on_demand=False)
(Constructor)

source code

Initialization method for the SyncThread.

Parameters:

name (str) - the name of the ROS master synchronized with.
uri (str) - the URI of the ROS master synchronized with
discoverer_name (str) - the name of the discovery node running on ROS master synchronized with.
monitoruri (str) - The URI of RPC server of the discovery node to get the ROS master state by calling a method only once.
timestamp (float64) - The timestamp of the current state of the ROS master info.
sync_on_demand (bool) - Synchronize topics on demand

Overrides: object.__init__

update(self, name, uri, discoverer_name, monitoruri, timestamp)

source code

Sets a request to synchronize the local ROS master with this ROS master.

Parameters:

name (str) - the name of the ROS master synchronized with.
uri (str) - the URI of the ROS master synchronized with
discoverer_name (str) - the name of the discovery node running on ROS master synchronized with.
monitoruri (str) - The URI of RPC server of the discovery node to get the ROS master state by calling a method only once.
timestamp (float64) - The timestamp of the current state of the ROS master info.

Note: If currently a synchronization is running this request will be ignored!

setOwnMasterState(self, own_state, sync_on_demand=False)

source code

Sets the state of the local ROS master state. If this state is not None, the topics on demand will be synchronized.

Parameters:

own_state (master_discovery_fkie/MasterInfo) - the state of the local ROS master state
sync_on_demand (bool) - if True, sync only topic, which are also local exists (Default: False)
