java.lang.Object org.apache.wicket.util.upload.DiskFileItemFactory
public class DiskFileItemFactory
The default FileItemFactory
implementation. This
implementation creates FileItem
instances which keep their
content either in memory, for smaller items, or in a temporary file on disk, for larger items.
The size threshold, above which content will be stored on disk, is configurable, as is the
directory in which temporary files will be created.
If not otherwise configured, the default configuration values are as follows:
System.getProperty("java.io.tmpdir")
.
