我在我的UML图中放了'const'吗？

Question

I'm making a UML diagram using Dia . Do I need to put const in the diagram when a function is const ? If so, where?

Answer 1

Chapter 11.8.2 ("Operation") in the latest UML specification lists isQuery as one of the operation's attributes:

isQuery : Boolean - Specifies whether an execution of the Operation leaves the state of the system unchanged (isQuery=true) or whether side effects may occur (isQuery=false). The default value is false.

If operation that does not change system's state is shown in a diagram, property {query} should be added after function's return type.

Dia supports isQuery attribute for class' operations: open class' Properties window and in Operations tab tick Query checkbox for method that does not change class' state and const will appear after method's return type in a diagram.
