4.2.2 Containment tree terminology
Refer to 4.2.1 - Graphical representation of the containment tree on page 41 for a figure of a containment
tree.
The following table explains the terminology associated with the containment tree:
Term Description
containment tree The containment tree represents the hierarchical structure of the Telindus 1031
Router. It is composed of a number of objects that are ordered in a tree. This tree
resembles a Windows directory structure:
• it is also a levelled structure, with nodes which can be expanded or reduced.
• the containment tree objects can be compared with file folders.
• the objects contain attributes like file folders contain files.
object An object represents a physical interface, an application or a combination of both.
Each object has its own set of attributes.
parent and child
object Some objects are not present in the containment tree by default. If you want to use
the features associated with such an object, then you have to add the object first.
You always add an object under another object. The object you add is called the
child object. The object under which you add this child object is called the parent
object.
index name Of some objects more than one object is present in the containment tree. The dif-
ferent objects are distinguished from one another by adding an index. E.g.
linePair[1]
and
linePair[2]
, where
1
and
2
are the indexes. Also child objects are given an index
(by the user when adding the object).
An index name is also often referred to as index , instance value or instance name .
attribute An attribute is a parameter related to a certain object. It has a certain value.
value An attribute has a certain value which is …
• changeable in case of a configuration attribute (provided you have write
access).
• read only in case of a status, performance and alarm attribute.
structured value Some attribute values contain underlying values: a structured value. These values
are displayed in the structured value window. If an attribute contains structured val-
ues, then a bit string,
<Table>
or
<Struct>
is displayed after the attribute.
A structured value is also often referred to as just structure .
