com.sun.tools.javac.main.JavaCompiler

JavaCompiler provides (and enforces) a use-once method to compile a list of source files. It invokes the various phases of the compiler to cause those source files to be compiled.

• All the files given on the command line are parsed, to build a list of parse trees. Lexing and parsing are done with Scanner and Parser. Lexical and syntax errors will be detected here.

  Note: Additional files may be parsed later, if they are found on the class/source path, and if they are newer than their matching class file.

• For each of the parse trees, their symbols are "entered", using Enter. This will also set up a "to do" list of additional work to be done to compile those parse trees. (more...)
• If source code or stub code will be generated, a list is made (in rootClasses) of all the top level classes defined in the parse trees. This will be used later, to check whether a class being processed was directly provided on the command line or not.
• Then, for as long as there is work on the "to do" list, JavaCompiler processes entries from the "to do" list. In so doing, the compiler might find additional classes that need to be processed, which may result in additional entries being added to the "to do" list. (more...)
• Print final messages.
• Return a list of class symbols, perhaps just those from final lower (may not include top level classes)
