com.webobjects.foundation.NSMutableArray
Bugfix reimplementation of NSMutableArray. To be able to use this class, the framework this class resides in must be before JavaFoundation.framework in your classpath.
It fixes a lot of issues:
- implements the correct Collection methods, so you can anArray.add(anObject)
- has several performance improvements that make EOF faster by several orders of magnitude when you have large record sets
- fixes a bug when the actual objects were handed out replaceObjectAtIndex()
- fixes a bug when the iterator method wasn't firing a fault in _EOCheapCopyMutableArray
Once these issues are resolved in a WO distribution, this class will go away and the Apple supplied will will be used again without changes in code on your side.
@param < E> type of array contents
NSMutableArray のバッグフィックス再実装。このクラスを使用する為には現フレームワークのクラスパスが JavaFoundation.framework の前にある必要があります。
次の問題を対応しています:
- 正しいコレクション・メソッドの実装：anArray.add(anObject) が可能
- 大きなレコード・セットの場合でのスピード改良で EOF が早くなるのです
- 実際のオブジェクトが replaceObjectAtIndex() の外で処理されるバッグフィックス
- _EOCheapCopyMutableArray でのフォルトはトリーガされない問題のバッグフィックス
