if (++curIndex >= _collection.Count) { return false; } else { // Set current box to next item in collection. curBox = _collection[curIndex]; } return true; } public void Reset() { curIndex = -1; } void IDisposable.Dispose() { } public Box Current { get { return curBox; } ...
Thecollection interfacesare divided into two groups. The most basic interface,java.util.Collection, has the following descendants: java.util.Set java.util.SortedSet java.util.NavigableSet java.util.Queue java.util.concurrent.BlockingQueue java.util.concurrent.TransferQueue ...
Note: In a way, it works in an opposite way from a “normal” Java type assignment. For example, Employee emp = new Manager(); makes emp object an instance of Manager. But in the case of generics: ArrayList[Manager] managementTeam = new ArrayList[](); ...
To keep the number of methods in each core interface small, an interface contains a method only if either: It is a trulyfundamental operation: a basic operations in terms of which others could be reasonably defined, There is a compelling performance reason why an important implementation would ...
