/** |
|
35 |
* This class extends FileTypeMap and provides data typing of files |

|
38 |
* <b>MIME types file search order:</b><p> |
|
39 |
* The MimetypesFileTypeMap looks in various places in the user's |
|
40 |
* system for MIME types file entries. When requests are made |
|
41 |
* to search for MIME types in the MimetypesFileTypeMap, it searches |
|
42 |
* MIME types files in the following order: |
|
43 |
* <p> |
|
44 |
* <ol> |
|
45 |
* <li> Programmatically added entries to the MimetypesFileTypeMap instance. |
|
46 |
* <li> The file <code>.mime.types</code> in the user's home directory. |
|
47 |
* <li> The file <<i>java.home</i>><code>/lib/mime.types</code>. |
|
48 |
* <li> The file or resources named <code>META-INF/mime.types</code>. |
|
49 |
* <li> The file or resource named <code>META-INF/mimetypes.default</code> |
|
50 |
* (usually found only in the <code>activation.jar</code> file). |
|
51 |
* </ol> |
|
52 |
* <p> |
|
53 |
* <b>MIME types file format:</b><p> |
|
54 |
* |
|
55 |
* <code> |
|
56 |
* # comments begin with a '#'<br> |
|
57 |
* # the format is <mime type> <space separated file extensions><br> |
|
58 |
* # for example:<br> |
|
59 |
* text/plain txt text TXT<br> |
|
60 |
* # this would map file.txt, file.text, and file.TXT to<br> |
|
61 |
* # the mime type "text/plain"<br> |
