36 <h3>com.sun.tools.javac.main.Main</h3> |
|
37 |
|
38 <p> |
|
39 The normal main entry point is |
|
40 <a href="../../src/share/classes/com/sun/tools/javac/main/Main.java" class=code>com.sun.tools.javac.main.Main</a>, |
|
41 with a public API entry point at |
|
42 <a href="../../src/share/classes/com/sun/tools/javac/Main.java" class=code>com.sun.tools.javac.Main</a> which just calls down to <code>com.sun.tools.javac.main.Main</code>. |
|
43 </p> |
|
44 |
|
45 <p>The various parts of the compiler share common information by means of a |
|
46 <a href="../../src/share/classes/com/sun/tools/javac/util/Context.java" class=code>Context</a>. |
|
47 Every invocation of the compiler must have its own Context. |
|
48 |
|
49 <p> |
|
50 <code>com.sun.tools.javac.main.Main</code> does command line processing to determine the list of files to be compiled, and any applicable options. There are four types of options: |
|
51 <ul> |
|
52 <li>standard public options, e.g. <code>-classpath</code> |
|
53 <li>extended public options, beginning -X, e.g. <code>-Xlint</code> |
|
54 <li>hidden options -- not public or documented, e.g. -fullversion |
|
55 <li>even more hidden options -- typically for debugging the compiler, beginning -XD, e.g. -XDrawDiagnostics |
|
56 </ul> |
|
57 |
|
58 If there are files to be compiled, <code>Main</code> invokes |
|
59 <a href="../../src/share/classes/com/sun/tools/javac/main/JavaCompiler.java" class=code>JavaCompiler</a> <i>(<a href="JavaCompiler.html">more...</a>)</i> |
|
60 After <code>JavaCompiler</code> completes, the list of class symbols that was returned is discarded. |
|
61 </p> |
|
62 |
|
63 <p> |
|
64 Any and all exceptions are caught and handled, and a return code is |
|
65 determined. Finally, the compiler exits. |
