88 |
* Utility methods and classes for writing jtreg tests for |
|
89 |
* javac, javah, javap, and sjavac. (For javadoc support, |
|
90 |
* see JavadocTester.) |
|
91 |
* |
|
92 |
* <p>There is support for common file operations similar to |
|
93 |
* shell commands like cat, cp, diff, mv, rm, grep. |
|
94 |
* |
|
95 |
* <p>There is also support for invoking various tools, like |
|
96 |
* javac, javah, javap, jar, java and other JDK tools. |
|
97 |
* |
|
98 |
* <p><em>File separators</em>: for convenience, many operations accept strings |
|
99 |
* to represent filenames. On all platforms on which JDK is supported, |
|
100 |
* "/" is a legal filename component separator. In particular, even |
|
101 |
* on Windows, where the official file separator is "\", "/" is a legal |
|
102 |
* alternative. It is therefore recommended that any client code using |
|
103 |
* strings to specify filenames should use "/". |
