Niall Pemberton updated IO-119:
-------------------------------

    Attachment: FileFilterBuilderTestCase.java
                FileFilterBuilder.java

Isn't that what we already have in FileFilterUtils?
http://commons.apache.org/io/api-release/org/apache/commons/io/filefilter/FileFilterUtils.html

New version attached - I don't think theres an intuitive way to do and/or together - so I've simplified by removing that, add singleton instances for AND/OR, added regex and provided better size / lastmodified methods.

 So for example, to create a file filter for the following conditions
  - Either, directories which are not hidden and not named ".svn"
  - or, files which have a suffix of ".java"

    FileFilterBuilder directoryBuilder = FileFilterBuilder.AND
                           .isDirectory()
                           .isHidden(false)
                           .not().name(".svn");
 
     FileFilterBuilder fileBuilder = FileFilterBuilder.AND
                          .isFile()
                          .suffix(".java");

    FileFilter filter = FileFilterBuilder.OR
                          .add(directoryBuilder)
                          .add(fileBuilder)
                          .toFileFilter();

> I'd like to add a new convenience "builder" class (FileFilterBuilder) to make it easier to create complex FileFilter using Commons IO's IOFileFilter implementations.
> Heres an example of how it can be used to create a IOFileFilter for the following conditions:
>  - Either, directories which are not hidden and not named ".svn"
>  - or, files which have a suffix of ".java"
>     IOFileFilter filter = FileFilterBuilder.orBuilder()
>         .and().isDirectory().isHidden(false).not().name(".svn").end()
>         .and().isFile().suffix(".java").end()
>         .getFileFilter();
