*
* TPriorityList implements a priority ordered list collection class. It allows you to specify
- * floating numbers for priorities up to a specific precision. There is also a default priority if
- * no priority is specified. If you replace TList with this class it will work exactly the same with
- * priorities set to the default.
+ * any numeric for priorities down to a specific precision. The lower the numeric, the high the priority of the item in the
+ * list. Thus -10 has a higher priority than -5, 0, 10 (the default), 18, 10005, etc. Per {@link round}, precision may be negative and
+ * thus rounding can go by 10, 100, 1000, etc, instead of just .1, .01, .001, etc. The default precision allows for 8 decimal
+ * places. There is also a default priority of 10, if no different default priority is specified or no item specific priority is indicated.
+ * If you replace TList with this class it will work exactly the same with items inserted set to the default priority, until you start
+ * using different priorities than the default priority.
*
- * As you access the array features of this class it flattens and caches the results. It flushes the
- * cache when elements are changed.
+ * As you access the PHP array features of this class, it flattens and caches the results. If at all possible, this
+ * will keep the cache fresh even when manipulated. If this is not possible the cache is cleared.
+ * When an array of items are needed and the cache is outdated, the cache is recreated from the items and their priorities
*
* You can access, append, insert, remove an item by using
- * {@link itemAt}, {@link add}, {@link insertAt}, {@link insertAtPriority}, and {@link remove}.
+ * {@link itemAt}, {@link add}, {@link insertAt}, and {@link remove}.
* To get the number of the items in the list, use {@link getCount}.
* TPriorityList can also be used like a regular array as follows,
* <code>
- * $list[]=$item; // append with the default priority
- * $list[$index]=$item; // $index must be between 0 and $list->Count. This sets the element regardless of priority. Priority stays the same.
+ * $list[]=$item; // append with the default priority. It may not be the last item if other items in the list are prioritized after the default priority
+ * $list[$index]=$item; // $index must be between 0 and $list->Count-1. This sets the element regardless of priority. Priority stays the same.
+ * $list[$index]=$item; // $index is $list->Count. This appends the item to the end of the list with the same priority as the last item in the list.
* unset($list[$index]); // remove the item at $index
* if(isset($list[$index])) // if the list has an item at $index
* foreach($list as $index=>$item) // traverse each item in the list in proper priority order and add/insert order
* $n=count($list); // returns the number of items in the list
* </code>
*
- ** To extend TPriorityList by doing additional operations with each addition or removal
- ** operation, override {@link insertAtIndexInPriority()} and {@link removeAtIndexInPriority()}.
+ * To extend TPriorityList for doing your own operations with each addition or removal,
+ * override {@link insertAtIndexInPriority()} and {@link removeAtIndexInPriority()} and then call the parent.
