Method Details

__init__(self, name, parent=None, has_remote_launched_nodes=False, is_group=False)
(Constructor)

source code 

Initialize the GroupItem object with given values.

Parameters:
  • name (str) - the name of the group
  • parent (QtGui.QStandardItem) - the parent item. In most cases this is the HostItem. The variable is used to determine the different columns of the NodeItem.
Overrides: object.__init__

is_in_cap_group(self, nodename, config, ns, groupname)

source code 

Returns `True` if the group contains the node.

Parameters:
  • nodename (str) - the name of the node to test
  • config (str) - the configuration name
  • ns (str) - namespace
  • groupname (str) - the group name
Returns: bool
`True`, if the nodename is in the group

addCapabilities(self, config, capabilities, masteruri)

source code 

Add new capabilities. Based on this capabilities the node are grouped. The view will be updated.

Parameters:
  • config (str) - The name of the configuration containing this new capabilities.
  • masteruri (str) - The masteruri is used only used, if new nodes are created.
  • capabilities (dict(namespace: dict(group:dict('type' : str, 'images' : [str], 'description' : str, 'nodes' : [str])))) - The capabilities, which defines groups and containing nodes.

move_nodes2group(self, group_item, config, ns, groupname, host_item)

source code 

Returns `True` if the group was changed by adding a new node.

Parameters:
  • GroupItem, group_item - item to parse the children for nodes.
  • str, config - the configuration name
  • str, ns - namespace
  • str, groupname - the group name
  • HostItem, host_item - the host item contain the capability groups
Returns: bool
`True`, if the group was changed by adding a new node.

remCapablities(self, config)

source code 

Removes internal entry of the capability, so the new nodes are not grouped. To update view NodeTreeModel.removeConfigNodes() and GroupItem.clearUp() must be called.

Parameters:
  • config (str) - The name of the configuration containing this new capabilities.

getCapabilityGroups(self, node_name)

source code 

Returns the names of groups, which contains the given node.

Parameters:
  • node_name (str) - The name of the node
Returns: dict(config : [str])
The name of the configuration containing this new capabilities.

getNodeItemsByName(self, node_name, recursive=True)

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
  • recursive (bool) - Searches in (sub) groups
Returns: [QtGui.QStandardItem]
The list with node items.

getNodeItems(self, recursive=True)

source code 

Returns all nodes in this group and subgroups.

Parameters:
  • recursive (bool) - returns the nodes of the subgroups
Returns: [QtGui.QStandardItem]
The list with node items.

getGroupItem(self, group_name, is_group=True, nocreate=False)

source code 

Returns a GroupItem with given name. If no group with this name exists, a new one will be created. Assumption: No groups in group!!

Parameters:
  • group_name (str) - the name of the group
  • nocreate - avoid creation of new group if not exists. (Default: False)
Returns: GroupItem
The group with given name

addNode(self, node, cfg='')

source code 

Adds a new node with given name.

Parameters:
  • node (NodeInfo) - the NodeInfo of the node to create
  • cfg (str) - The configuration, which describes the node

clearUp(self, fixed_node_names=None)

source code 

Removes not running and not configured nodes.

Parameters:
  • fixed_node_names ([str]) - If the list is not None, the node not in the list are set to not running!

updateRunningNodeState(self, nodes)

source code 

Updates the running state of the nodes given in a dictionary.

Parameters:

getRunningNodes(self)

source code 

Returns the names of all running nodes. A running node is defined by his PID.

Returns: [str]
A list with node names

See Also: master_dicovery_fkie.NodeInfo

markNodesAsDuplicateOf(self, running_nodes, is_sync_running=False)

source code 

While a synchronization same node on different hosts have the same name, the nodes with the same on other host are marked.

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 errors.

updateTooltip(self)

source code 

Creates a tooltip description based on text set by updateDescription() and all childs of this host with valid sensor description. The result is returned as a HTML part.

Returns: str
the tooltip description coded as a HTML part

updateDescription(self, descr_type, descr_name, descr)

source code 

Sets the description of the robot. To update the tooltip of the host item use updateTooltip().

Parameters:

type(self)

source code 
Overrides: PyQt4.QtGui.QStandardItem.type

__eq__(self, item)
(Equality operator)

source code 

Compares the name of the group.

Overrides: PyQt4.QtGui.QStandardItem.__eq__

__ne__(self, item)

source code 

x!=y

Overrides: PyQt4.QtGui.QStandardItem.__ne__
(inherited documentation)

__gt__(self, item)
(Greater-than operator)

source code 

Compares the name of the group.

Overrides: PyQt4.QtGui.QStandardItem.__gt__
