Question

Pharo 2.0更改了一些基本的API位，我无法找到执行以下操作的新方法：

FileDirectory default directoryNamed: aFolderString.
FileDirectory on: aFilename.
FileDirectory default assureExistenceOfPath: aString.
ReferenceStream on: stream.

新的等效代码是什么？是否有可用于描述如何翻译或移植代码的更新指南？

Answer 1

以下陈述与你提出的问题相对应。

FileSystem workingDirectory / aFolderString
aFilename asFileReference
aString asFileReference ensureDirectory
2.0中不再存在ReferenceStream。

aPathString asFileReference会解析aPathString，所以如果你的名字中有斜杠，你将会进入一个子目录。

/将单个目录或文件名作为参数，并且不解析其他子目录。根据您的平台，您可以使用foo/bar轻松引用名为FileSystem workingDirectory / 'foo/bar'的文件，名称为斜杠。

不再支持ReferenceStream，并已在Pharo 2.0中删除。您应该使用写得很好，记录良好，经过良好测试且速度非常快的燃料。 http://rmod.lille.inria.fr/web/pier/software/Fuel

将代码移植到Pharo 2.0
