Class StringArrayList

java.lang.Object

net.oneandone.mork.misc.StringArrayList

All Implemented Interfaces:

Serializable

public class StringArrayList
extends Object
implements Serializable

TODO: dump List of Strings. Similar to java.util.List or java.util.ArrayList, but elements are Strings. Generic collections for Java would remove the need for StringArrayList. I chose to name the class StringArrayList instead of StringArrayList because it is shorter. I have implemented only those methods from ArrayList that I actually need.
