Designing with PlantUML: Creating and Defining Interfaces in Component Diagrams

Interfaces in component diagrams show how components are wired together and interact with each other. Interfaces are defined using brackets ()

 

Example

() "My Interface"

 

You can also use the interface keyword to define the interface.

 

Example

interface "My Interface"

 

You can define an alias to the interface using ‘as’ keyword.

 

() "My Interface" as MI

interface "My Interface" as MI
