Properties

Inherited from object: __class__

Method Details

__init__(self, host_address, masteruri, parent=None)
(Constructor)

source code 

Initialize the model.

Overrides: object.__init__

flags(self, index)

source code 
Overrides: PyQt4.QtCore.QAbstractItemModel.flags

getHostItem(self, masteruri, address)

source code 

Searches for the host item in the model. If no item is found a new one will created and inserted in sorted order.

Parameters:
  • masteruri (str) - ROS master URI
  • address (str) - the address of the host
Returns: HostItem
the item associated with the given master

updateModelData(self, nodes)

source code 

Updates the model data.

Parameters:
  • nodes (dict(str:NodeInfo, ...)) - a dictionary with name and info objects of the nodes.

set_std_capablilities(self, capabilities)

source code 

Sets the default capabilities description, which is assigned to each new host.

Parameters:
  • capabilities (dict(namespace: dict(group:dict('type' : str, 'description' : str, 'nodes' : [str])))) - the structure for capabilities

addCapabilities(self, masteruri, host_address, cfg, capabilities)

source code 

Adds groups to the model

Parameters:
  • masteruri (str) - ROS master URI
  • host_address (str) - the address the host
  • cfg (str or (str, str))) - the configuration name (launch file name or tupel for default configuration)
  • capabilities (dict(namespace: dict(group:dict('type' : str, 'description' : str, 'nodes' : [str])))) - the structure for capabilities

appendConfigNodes(self, masteruri, host_address, nodes)

source code 

Adds nodes to the model. If the node is already in the model, only his configuration list will be extended.

Parameters:
  • masteruri (str) - ROS master URI
  • host_address (str) - the address the host
  • nodes (dict(str : str)) - a dictionary with node names and their configurations

removeConfigNodes(self, cfg)

source code 

Removes nodes from the model. If node is running or containing in other launch or default configurations , only his configuration list will be reduced.

Parameters:
  • cfg (str) - the name of the confugration to close

getNode(self, node_name)

source code 

Since the same node can be included by different groups, this method searches for all nodes with given name and returns these items.

Parameters:
  • node_name (str) - The name of the node
Returns: [PySide.QtGui.QStandardItem]
The list with node items.

markNodesAsDuplicateOf(self, running_nodes, is_sync_running=False)

source code 

If there are a synchronization running, you have to avoid to running the node with the same name on different hosts. This method helps to find the nodes with same name running on other hosts and loaded by a configuration. The nodes loaded by a configuration will be inform about a currently running nodes, so a warning can be displayed!

Parameters:
  • running_nodes (dict(str:str)) - The dictionary with names of running nodes and their masteruri
  • is_sync_running (bool) - If the master_sync is running, the nodes are marked as ghost nodes. So they are handled as running nodes, but has not run informations. This nodes are running on remote host, but are not syncronized because of filter or errrors.

updateHostDescription(self, masteruri, host, descr_type, descr_name, descr)

source code 

Updates the description of a host.

Parameters:

Instance Variable Details

hostInserted(...)

source code 
the Qt signal, which is emitted, if a new host was inserted. Parameter: QtCore.QModelIndex of the inserted host item

Property Details

local_addr

Get Method:
unreachable.local_addr(self)
