33 |
* <p> A URL stream handler provider is a concrete subclass of this class that |
29097 | 34 |
* has a zero-argument constructor. URL stream handler providers may be |
35 |
* installed in an instance of the Java platform by adding them to the |
|
36 |
* application class path. |
|
37 |
* |
|
38 |
* <p> A URL stream handler provider identifies itself with a |
|
39 |
* provider-configuration file named java.net.spi.URLStreamHandlerProvider in |
|
40 |
* the resource directory META-INF/services. The file should contain a list of |
|
41 |
* fully-qualified concrete URL stream handler provider class names, one per |
|
42 |
* line. |
