Examples of org.eclipse.jgit.revwalk.RevWalk.parseTree()

org.eclipse.jgit.revwalk.RevWalk.parseTree()
Locate a reference to a tree.
This method only returns successfully if the tree object exists, is verified to be a tree. @param id name of the tree object, or a commit or annotated tag that may reference a tree. @return reference to the tree object. Never null. @throws MissingObjectException the supplied tree does not exist. @throws IncorrectObjectTypeException the supplied id is not a tree, a commit or an annotated tag. @throws IOException a pack file or loose object could not be read.
