/** |
|
|
|
|
|
* Task to determine the basename of a specified file, optionally minus a |
|
|
|
|
|
* specified suffix. |
|
|
|
|
|
* |
|
|
|
|
|
* This task can accept the following attributes: |
|
|
|
|
|
* <ul> |
|
|
|
|
|
* <li>file |
|
|
|
|
|
* <li>property |
|
|
|
|
|
* <li>suffix |
|
|
|
|
|
* </ul> |
|
|
|
|
|
* The <b>file</b> and <b>property</b> attributes are required. The |
|
|
|
|
|
* <b>suffix</b> attribute can be specified either with or without |
|
|
|
|
|
* the ".", and the result will be the same (ie., the |
|
|
|
|
|
* returned file name will be minus the .suffix). |
|
|
|
|
|
* <p> |
|
|
|
|
|
* When this task executes, it will set the specified property to the |
|
|
|
|
|
* value of the last element in the specified file. If file is a |
|
|
|
|
|
* directory, the basename will be the last directory element. If file |
|
|
|
|
|
* is a full-path filename, the basename will be the simple file name. |
|
|
|
|
|
* If a suffix is specified, and the specified file ends in that suffix, |
|
|
|
|
|
* the basename will be the simple file name without the suffix. |
