[jira] [Commented] (IO-328) FileUtils.listFilesAndDirs includes original dir in results even when it doesn't match filter

["Sebb (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IO-328?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13633443#comment-13633443 ] 

Sebb commented on IO-328:
-------------------------

I think the Javadoc is correct as it stands, though perhaps a bit ambiguous.

The Javadoc says:

bq. All files found are filtered by an IOFileFilter.

Directories are not mentioned.

bq. The resulting collection includes the subdirectories themselves.

That is ambiguous; it should probably read:

bq. The resulting collection includes the directories themselves.

> listFilesAndDirs seems to always include the "directory" passed as input in it's resulting Collection.  This is unexpected given the docs for the method...
> bq. Finds files within a given directory (and optionally its subdirectories). All files found are filtered by an IOFileFilter. 
> * the "given directory" is not a subdirectory of itself
> * it is not subjected to the IOFileFilter dirFilter, it is always added.
