FileItemFactory
DefaultFileItemFactory
public class DiskFileItemFactory extends java.lang.Object implements FileItemFactory
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")
.Modifier and Type | Field | Description |
