Examples of aleph.dir.DirectoryManager.open()

aleph.dir.DirectoryManager.open()
Open a global object in desired mode. All transaction managers should support at least modes "w" (write) and "r" (read) Unrecognized modes should be treated like "w". Modes are case insensitive. @param key The object to open. @param mode Mode in which to open object.
