Annotation Interface GetValue

@Target(PARAMETER) @Retention(RUNTIME) public @interface GetValue
A parameter source annotation that gets a value for a certain data key.

This value can be taken from the event cause's first ValueContainer, or any preceding parameter that inherits from ValueContainer.

When looking for a value, searching will start from the parameter immediately before the annotated one, moving backwards and checking the first ValueContainer in the event cause last.
