## com.beasys.commerce.util
Class SerializableEnumeration

    java.lang.Object
      com.beasys.commerce.util.SerializableEnumeration

All Implemented Interfaces:
  Enumeration, Serializable

public class SerializableEnumeration
extends Object
implements Enumeration, Serializable

An implementation of the Enumeration interface which is Serializable.

Note: Since most Enumeration implementations aren't Serializable (including Vector.elements() and Collections.enumeration()), we need this to return Enumerations from SessionBeans and other RemoteObjects. Most collection classes are Serializable, so that's nice. However, to make life easier, this uses the underlying Collection's iterator, most of which also aren't Serializable. Therefore, if a partial enumeration has been done before this Enumeration is serialized, the enumeration will start over on the other side because this internally keeps the Collection's Iterator in a transient field (since Iterator aren't generally Serializable).

This is also intentionally not thread-safe.

Since:
  2.0.1-sp1

  Serialized Form
