Ryan McKinley updated LABS-197:
-------------------------------

    Attachment: LABS-197-taskValidator.patch

here is one approach...  the interface is:

public interface TaskValidator {
  public Task validateTask( Task task ) throws InvalidTaskException;
}

the Validator may change the task so it is valid (perhaps normalize a URL or 
something) or throw an exception.

In this patch, the SimpleTaskQueue also implements TaskValidator and checks for 
"maxSize"



> 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}
