Chapter 3 Building Structural Diagrams
You can create the following types of objects in a composite structure diagram:
| Object | Tool | Symbol | Description |
|---|---|---|---|
| Class | 
|
|
Set of objects sharing the same attributes, operations, methods, and relationships. See "Classes (OOM)". |
| Interface | 
|
|
Descriptor for the externally visible operations of a class, object, or other entity without specification of internal structure. See "Interfaces (OOM)". |
| Port | 
|
|
Interaction point between a classifier and its environment. See "Ports (OOM)". |
| Part | 
|
|
Classifier instance playing a particular role within the context of another classifier. See "Parts (OOM)". |
| Generalization | 
|
|
Link between classes showing that the sub-class shares the structure or behavior defined in one or more superclasses. See "Generalizations (OOM)". |
| Require Link | 
|
|
Connects classifiers to interfaces. See "Require Links (OOM)". |
| Assembly Connector |
|
|
Connects parts to each other. See "Assembly Connectors (OOM)". |
| Delegation Connector |
|
|
Connects parts to ports on the outside of classifiers. See "Delegation Connectors (OOM)". |
| Association | 
|
|
Structural relationship between objects of different classes. See "Associations (OOM)". |
| Aggregation | 
|
|
A form of association that specifies a part-whole relationship between a class and an aggregate class (example: a car has an engine and wheels). See "Associations (OOM)". |
| Composition | 
|
|
A form of aggregation but with strong ownership and coincident lifetime of parts by the whole; the parts live and die with the whole (example: an invoice and its invoice line). See "Associations (OOM)". |
| Dependency | 
|
|
Relationship between two modeling elements, in which a change to one element will affect the other element. See "Dependencies (OOM)". |
| Realization | 
|
|
Semantic relationship between classifiers, in which one classifier specifies a contract that another classifier guarantees to carry out. See "Realizations (OOM)". |
| Attribute | N/A | N/A | Named property of a class. See "Associations (OOM)". |
| Operation | N/A | N/A | Service that can be requested from a class. See "Operations (OOM)". |
