class msiempy.device.DevTree(NitroList): (source)

View In Hierarchy

List-Like object. ESM device tree interface.

  • __contains__ method returns: (bool) True/None the name or IP matches the provided search term.

Exemple (list datasources):

>>> from msiempy.device import DevTree
>>> devtree = DevTree()
>>> print("All Datasources")
>>> print(devtree.get_text(fields=["parent_name", "name", "ds_id"]))
Note:
Uses internal API methods such as GRP_GETVIRTUALGROUPIPSLISTDATA to assemble DevTree object.

Method json JSON list of dicts representing the list.
Method perform Wrapper to execute a function on the list of elements
Static Method _confirm_func Ask user inut to confirm the calling of func on elements.

Inherited from NitroObject (via NitroList):
