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

org.eclipse.jgit.revwalk.RevWalk.markStart()
Mark a commit to start graph traversal from.
Callers are encouraged to use {@link #parseCommit(AnyObjectId)} to obtainthe commit reference, rather than {@link #lookupCommit(AnyObjectId)}, as this method requires the commit to be parsed before it can be added as a root for the traversal.
The method will automatically parse an unparsed commit, but error handling may be more difficult for the application to explain why a RevCommit is not actually a commit. The object pool of this walker would also be 'poisoned' by the non-commit RevCommit. @param c the commit to start traversing from. The commit passed must be from this same revision walker. @throws MissingObjectException the commit supplied is not available from the object database. This usually indicates the supplied commit is invalid, but the reference was constructed during an earlier invocation to {@link #lookupCommit(AnyObjectId)}. @throws IncorrectObjectTypeException the object was not parsed yet and it was discovered during parsing that it is not actually a commit. This usually indicates the caller supplied a non-commit SHA-1 to {@link #lookupCommit(AnyObjectId)}. @throws IOException a pack file or loose object could not be read.
