Examples of org.eclipse.jgit.lib.ObjectLoader.openStream()

org.eclipse.jgit.lib.ObjectLoader.openStream()
Obtain an input stream to read this object's data. @return a stream of this object's data. Caller must close the stream whenthrough with it. The returned stream is buffered with a reasonable buffer size. @throws MissingObjectException the object no longer exists. @throws IOException the object store cannot be accessed.
