2001-10-15 Bryce McKinlay <bryce@waitaki.otago.ac.nz> * java/util/HashMap.java (HashEntry.clone): Removed. (HashMap(Map)): Use putAllInternal. (clone): Likewise. (putAllInternal): New method. Efficient counterpart to putAll which does not call put(). * java/util/LinkedHashMap.java (rethread): Removed. (putAllInternal): New method. Clear "head" and "tail". (addEntry): New argument "callRemove". Don't call removeEldestEntry() if callRemove == false. * Makefile.am: Add new classes RandomAccess and LinkedHashMap. * Makefile.in: Rebuilt. 2001-10-15 Eric Blake <ebb9@email.byu.edu> * java/util/Collection.java: Updated javadoc. * java/util/Comparator.java: Updated javadoc. * java/util/Enumeration.java: Updated javadoc. * java/util/Iterator.java: Updated javadoc. * java/util/List.java: Updated javadoc. * java/util/ListIterator.java: Updated javadoc. * java/util/Map.java: Updated javadoc. * java/util/RandomAccess.java: New file. * java/util/Set.java: Updated javadoc. * java/util/SortedMap.java: Updated javadoc. * java/util/SortedSet.java: Updated javadoc.

|
* be obtained by the enumeration method in class Collections.
