Chapter 6 Building Implementation Diagrams

Component diagram objects

You can create the following objects in a component diagram:

Object	Tool	Symbol	Description
Component			Represents a shareable piece of implementation of a system. See "Components".
Interface			Descriptor for the externally visible operations of a class, object, or other entity without specification of internal structure. See the "Interfaces" section in the "Building Structural Diagrams" chapter.
Port			Interaction point between a classifier and its environment. See the "Ports" section in the "Building Structural Diagrams" chapter.
Part			Classifier instance playing a particular role within the context of another classifier. See the "Parts" section in the "Building Structural Diagrams" chapter.
Generalization			A link between a general component and a more specific component that inherits from it and add features to it. See the "Generalizations" section in the "Building Structural Diagrams" chapter.
Realization			Semantic relationship between classifiers, in which one classifier specifies a contract that another classifier guarantees to carry out. See the "Realizations" section in the "Building Structural Diagrams" chapter.
Require Link			Connects components to interfaces. See the "Require Links" section in the "Building Structural Diagrams" chapter.
Assembly Connector			Connects parts to each other. See the "Assembly Connectors" section in the "Building Structural Diagrams" chapter.
Delegation Connector			Connects parts to ports on the outside of components. See the "Delegation Connectors" section in the "Building Structural Diagrams" chapter.
Dependency			Relationship between two modeling elements, in which a change to one element will affect the other element. See the "Dependencies" section in the "Building Structural Diagrams" chapter.
