/** |

* A URL Connection to a Java ARchive (JAR) file or an entry in a JAR |
|
38 |
* file. |
|
39 |
* |
|
40 |
* <p>The syntax of a JAR URL is: |
|
41 |
* |
|
42 |
* <pre> |
|
43 |
* jar:<url>!/{entry} |
|
44 |
* </pre> |
|
45 |
* |
|
46 |
* <p>for example: |
|
47 |
* |
|
19069 | 48 |
* <p>{@code jar:http://www.foo.com/bar/baz.jar!/COM/foo/Quux.class} |
2 | 49 |
* |
50 |
* <p>Jar URLs should be used to refer to a JAR file or entries in |
|
51 |
* a JAR file. The example above is a JAR URL which refers to a JAR |
|
52 |
* entry. If the entry name is omitted, the URL refers to the whole |
|
53 |
* JAR file: |
|
54 |
* |
|
19069 | 55 |
* {@code jar:http://www.foo.com/bar/baz.jar!/} |
2 | 56 |
* |
57 |
* <p>Users should cast the generic URLConnection to a |
|
58 |
* JarURLConnection when they know that the URL they created is a JAR |
|
59 |
* URL, and they need JAR-specific functionality. For example: |
|
60 |
* |
|
61 |
* <pre> |
|
62 |
* URL url = new URL("jar:file:/home/duke/duke.jar!/"); |
|
63 |
* JarURLConnection jarConnection = (JarURLConnection)url.openConnection(); |
|
64 |
* Manifest manifest = jarConnection.getManifest(); |
|
65 |
* </pre> |
|
66 |
* |
|
67 |
* <p>JarURLConnection instances can only be used to read from JAR files. |
|
68 |
* It is not possible to get a {@link java.io.OutputStream} to modify or write |
|
69 |
* to the underlying JAR file using this class. |
|
70 |
* <p>Examples: |
|
71 |
* |
|
72 |
* <dl> |
|
73 |
* |
|
74 |
* <dt>A Jar entry |
|
19069 | 75 |
* <dd>{@code jar:http://www.foo.com/bar/baz.jar!/COM/foo/Quux.class} |
2 | 76 |
* |
77 |
* <dt>A Jar file |
|
19069 | 78 |
* <dd>{@code jar:http://www.foo.com/bar/baz.jar!/} |
2 | 79 |
* |
80 |
* <dt>A Jar directory |
|
19069 | 81 |
* <dd>{@code jar:http://www.foo.com/bar/baz.jar!/COM/foo/} |
2 | 82 |
* |
83 |
* </dl> |
|
84 |
* |
|
21278 | 85 |
* <p>{@code !/} is referred to as the <em>separator</em>. |
2 | 86 |
* |
19069 | 87 |
* <p>When constructing a JAR url via {@code new URL(context, spec)}, |
2 | 88 |
* the following rules apply: |
89 |
* |
|
90 |
* <ul> |
|
91 |
* |
|
92 |
* <li>if there is no context URL and the specification passed to the |
|
93 |
* URL constructor doesn't contain a separator, the URL is considered |
|
94 |
* to refer to a JarFile. |
|
95 |
* |
|
96 |
* <li>if there is a context URL, the context URL is assumed to refer |
|
97 |
* to a JAR file or a Jar directory. |
|
98 |
* |
|
99 |
* <li>if the specification begins with a '/', the Jar directory is |
|
100 |
* ignored, and the spec is considered to be at the root of the Jar |
|
101 |
* file. |
|
102 |
* |
|
103 |
* <p>Examples: |
|
104 |
* |
|
105 |
* <dl> |
|
106 |
* |
|
107 |
* <dt>context: <b>jar:http://www.foo.com/bar/jar.jar!/</b>, |
