Защищенные методы

Метод	Описание
AcquireWriteLock ( ) : void	Tries to acquire the WriteLock on this directory. this method is only valid if this IndexReader is directory owner. if another writer has this index open (`write.lock` could not be obtained)
DoClose ( ) : void
DoCommit ( string>.IDictionary commitUserData ) : void	Commit changes resulting from delete, undeleteAll, or setNorm operations If an exception is hit, then either no changes or all changes will have been committed to the index (transactional semantics).
