Java command annotations are used for the developing Java commands in PAK.
This chapter describes the functionality of the @Run annotation.
It also gives an example of how you can use this annotation in your implementation.
1. Basics
The @Run annotation marks the entry method of a command and contains its business logic.
Each command class should use this annotation exactly once.
The method annotated with @Run has to have a public modifier and void as return type.
The name of the @Run method must not collide with the getter name of a class field.For further information please refer to the @Persistent documentation.
