A node is a run-time physical object on which components
may be deployed. In the UML metamodel it is a sub-class of
A node is represented on a class diagram as a three dimensional box, labeled with its name.
The details tabs that are active for nodes are as follows.
Standard tab. The
field defines the bounding box for the node on the
Beware that in the 0.18 release of ArgoUML, the bounding box just refers to the front face of the cube. This means that the three dimensional top and side may be ignored, for example when determining the limits of a diagram for saving graphics.
Standard tab, but with no contents.
A node should not generate any code, so having this tab active is probably a mistake.

Derived nodes still have their value in analysis to introduce useful names or concepts, and in design to avoid re-computation.
Navigate up through the package structure.
This creates a new reception, navigating immediately to the properties tab for that reception.
This creates a new Stereotype (see Section 16.6, “ Stereotype ”) for the selected node, navigating immediately to the properties tab for that stereotype.
This deletes the node from the model
This is a deletion from the model
not just the diagram. To delete
a node from the diagram, but keep it within the
model, use the main menu
Text box. The name of the node. The name of a node has a leading capital letter, with words separated by “bumpy caps”.
ArgoUML does not enforce this naming convention.
Drop down selector. Node is a type of classifier,
and so it has the default stereotypes of a classifier
as defined in the UML standard. ArgoUML provides the
standard stereotypes for a classifier:
icon. If a stereotype has been selected, this will navigate to the stereotype property panel (see Section 16.6, “ Stereotype ”).
Drop down selector. Allows altering the namespace for the node. This is the package hierarchy.
Check box, with entries
abstract is used to
declare that this node cannot be instantiated, but
must always be specialized. The name of an abstract
node is displayed in italics on the diagram.
leaf indicates that this
node cannot be further specialized.
root indicates the node
can have no generalization.
Text area. Lists any node that generalizes this node.
Button 1 double click navigates to the generalization and opens its property tab.
Text box. Lists any specialized node (i.e. for which this node is a generalization.
Button 1 double click navigates to the specialization and opens its property tab.
Text box. Lists any residents (see Section 23.4, “ Component ”) designed to be deployed on this type of node.
Button 1 double click navigates to the selected entry.
