From: Shawn O. Pearce Date: Tue, 20 Jul 2010 15:58:14 +0000 (-0700) Subject: Remove gitIgnoreTimestamp from abstract iterator API X-Git-Tag: v0.9.1~166 X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=refs%2Fchanges%2F54%2F1154%2F1;p=jgit.git Remove gitIgnoreTimestamp from abstract iterator API This never should have been exposed on the top of the AbstractTreeIterator type hierarchy. There is no concept of a timestamp in a canonical tree read from the object database, and the time in the DirCache isn't what we want here either. Actually all that we need is to find the files whose names are ".gitignore" and are below the root directory. We can accomplish that with a suffix filter, and process them immediately.
