Examples of SourceValidity

org.apache.excalibur.source.SourceValidity
A SourceValidity object contains all information to check if a Source object is still valid.
There are two possibilities:
- The validity object has all information to check by itself if it is valid (e.g. given an expires date).
- The validity object possibility needs another (newer) validity object to compare against (e.g. to test a last modification date).
To avoid testing what the actual implementation of the validity object supports, the invocation order is to first call {@link #isValid()} and only if this resultis 0 (i.e. "don't know"), then to call {@link #isValid(SourceValidity)}.
Remember to call {@link #isValid(SourceValidity)} when {@link #isValid()} returned0 ! @author Avalon Development Team @version CVS $Revision: 1.4 $ $Date: 2004/02/28 11:47:26 $
