| <h3>com.sun.tools.javac.main.Main</h3> |
| |
| <p> |
| The normal main entry point is |
| <a href="../../src/share/classes/com/sun/tools/javac/main/Main.java" class=code>com.sun.tools.javac.main.Main</a>, |
| with a public API entry point at |
| <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>. |
| </p> |
| |
| <p>The various parts of the compiler share common information by means of a |
| <a href="../../src/share/classes/com/sun/tools/javac/util/Context.java" class=code>Context</a>. |
| Every invocation of the compiler must have its own Context. |
| |
| <p> |
| <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: |
| <ul> |
| <li>standard public options, e.g. <code>-classpath</code> |
| <li>extended public options, beginning -X, e.g. <code>-Xlint</code> |
| <li>hidden options -- not public or documented, e.g. -fullversion |
| <li>even more hidden options -- typically for debugging the compiler, beginning -XD, e.g. -XDrawDiagnostics |
| </ul> |
| |
| If there are files to be compiled, <code>Main</code> invokes |
| <a href="../../src/share/classes/com/sun/tools/javac/main/JavaCompiler.java" class=code>JavaCompiler</a> <i>(<a href="JavaCompiler.html">more...</a>)</i> |
| After <code>JavaCompiler</code> completes, the list of class symbols that was returned is discarded. |
| </p> |
| |
| <p> |
| Any and all exceptions are caught and handled, and a return code is |
| determined. Finally, the compiler exits. |
