All Implemented Interfaces:

PropertiesCacheManager.Saveable

Enclosing class:

ListTemplate

public static class ListTemplate.MyList
extends java.util.Dictionary
implements PropertiesCacheManager.Saveable

Implement a list of strings. This uses a Vector for its internal implementation, and is a Dictionary to allow convenient access to portions of the list. By implementing Saveable, lists can participate in persistence.
