    <p>I am creating my own priority queue of sorts. It is not a typical priority queue in that items are inserted with a given priority. Rather items can be added to the queue and they begin at the highest priority(let say we have 5 queues, queue 1=highest priority, queue5=lowest)), so the item is added to queue 1 initially.</p> <p>The user of this data structure can get the next() element, which returns an element based on some factors that I am interested in, namely the priority, but it is not dequeued from the entire data structure. The user provides some feedback to the validity of the item returned from the previous call to next()(eg. a pass/fail result), and based on that, the item is moved up or down in priority. Basically, elements that fail get used less often and I have mechanisms to eventually remove elements that fail too often.</p> <p>1)Any suggestions to improve the interface? I do not like having to retrieve an element from the next() call and then provide feedback with another function call. There is too much room for error where the state gets messed up. (ie user does not report result before getting next element..etc...). Also, it would be desireable to allow this to be thread safe.</p> <p>2)I am using a private nested class that wraps the elements I am interested in along with some attributes associated with each element to track statistics on the element(eg pass/fail counts etc...), and would like to know if there was a way to access the outer class members from the inner class?</p>

    1. COa nested class has access to the private members of the outer class, provided it has a reference to the class instance.

    2. COOh cool, was hoping there was a way without passing in a reference to the object to all the inner class instances.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
