Class StaticFileAggregator

java.lang.Object
  dekoh.portal.util.StaticFileAggregator

public class StaticFileAggregator
extends Object

Helper class to include multiple files in a response. The given set of files are included in the response. The file paths can be absolute or relative (wrt the current context). It supports last modified headers. If n files are being included the largest lastmodified time for the included files is chosen. This has two assumptions:

1. All included files are static files
2. If files f1, f2, .... fn are modified at t1 < t2 < t3 < ... < tn. tn is chosen as the last modified for this response. Now if f3 is modified at time t31 where t3<t31<tn, the response will say not modified even though it has been modified
