类 DefaultFileRenamePolicy

java.lang.Object

com.oreilly.servlet.multipart.DefaultFileRenamePolicy

所有已实现的接口:

FileRenamePolicy

public class DefaultFileRenamePolicy
extends java.lang.Object
implements FileRenamePolicy

Implements a renaming policy that adds increasing integers to the body of any file that collides. For example, if foo.gif is being uploaded and a file by the same name already exists, this logic will rename the upload foo1.gif. A second upload by the same name would be foo2.gif. Note that for safety the rename() method creates a zero-length file with the chosen name to act as a marker that the name is taken even before the upload starts writing the bytes.
