Type Parameters:

T - type of the elements of the enumerator

E - type of the exceptions thrown by the enumerator

All Superinterfaces:

java.lang.AutoCloseable

public interface Enumerator<T,E extends java.lang.Exception>
extends java.lang.AutoCloseable

Enumerator should be used instead of java.utill.Enumeration class for methods that returns database records or that are invoked remotely. Emumerator differs from enumeration in two ways:

• The methods can throw an exception.
• There is method close, which allows the implementation to free got recources if the enumeration has not been read entirely. The implementation of this class should release implicitly if the method hasMoreElements returns false
