Directions for method parameters in class diagrams
What do "in", "out", and "inout" directions for method parameters mean?

Re: Directions for method parameters in class diagrams
Hi JaeHoonG,

Thank you for your post.

Here is the meaning of "in", "inout" and "out".

"in" indicates that parameters are passed into the behavior.

"inout" indicates that parameters are passed into the behavior
and then back out from the behavior.

"out" indicates that parameters are back out from behavior.

Please refer to the UML 2.5 specification. (9.4.3.4 - Parameter)
