public abstract class ZIPListInstaller
extends java.lang.Object

A ZIPListInstaller installs a list of ZIPs into a given local directory from a given download location. The installation directory and download URL are established when the installer is constructed. This is an abstract class: each concrete subclass is responsible for implementing the method establishZIPList() which defines the specific list of ZIPs to be installed, for which purpose the supporting setter methods setZIPs(String[]) and setZIPTags(String[]) are provided. The doInstall() method first establishes the list of ZIPs, by inovoking establishZIPList() and then performs the installation.
