| // This module defines methods in the ZipFile class associated to the FileFilter |
| // capability - selecting files to add into the archive, or selecting entries to |
| // retrieve from the archive based on criteria including the filename, size, date, or |
| // attributes. It is something like a "poor man's LINQ". I included it into DotNetZip |
| // because not everyone has .NET 3.5 yet. When using DotNetZip on .NET 3.5, the LINQ |
| // query/selection will be superior. |
| // |
| // These methods are segregated into a different module to facilitate easy exclusion for |
| // those people who wish to have a smaller library without this function. |
