penny.download.AbstractDownload

This class represents a AbstractDownload. It is the base class for all other downloads. This class and all classes that extend it should be used to track information on a download only. All other logic such as getting connections and save files should be implemented elsewhere. ex. DownloadConnectionFactory. AbstractDownload can be used to update a table model with property change listeners. It can also be used as a model object to update the download.db which uses DAO objects for different databases. It is important to understand how to update the two times stored in AbstractDownload: retryTime and downloadTime. Before each operation, for instance read() for AbstractDownload, initDownloadTime() must be called, then the operation, then updateDownloadTime(). This should be done in a loop so the time is constantly updated. It is also important to know that setting the status can cause an IllegalStateException. Since this is a runtime exception make sure to look for it. @author John J Mercier
