Thorsten Scherler commented on LABS-197:
----------------------------------------

Thinking about it we should have both.

"may change the task " may include linking it to an issue tracker or a resource 
tracker. 

One can even think of a validateTask implementation that ask per eMail 
notification the user to accept the tak. If she does per reply the pending 
validation will be checked again. 

Brainstorming: 
Maybe we need as well a getState() which will return one of
PENDING_STATE = "pending";
RUNNING_STATE="running";
ACCEPTED_STATE="accepted";
DENIED_STATE="denied";

> Create TaskValidator -- include concepts like: maxDepth and maxSize

> The TaskQueue should have an expendable way to check if a Task is valid.
> perhaps something like:
> {code:java}
>  
> public interface TaskValidator {
>   public boolean validateTask( Task task ) throws InvalidTaskException;
> }
> {code}
