/**
 * Interface to invoke Java programming language compilers from
 * programs.
 *
 * <p>The compiler might generate diagnostics during compilation (for
 * example, error messages).  If a diagnostic listener is provided,
 * the diagnostics will be supplied to the listener.  If no listener
 * is provided, the diagnostics will be formatted in an unspecified
 * format and written to the default output, which is {@code
 * System.err} unless otherwise specified.  Even if a diagnostic
 * listener is supplied, some diagnostics might not fit in a {@code
 * Diagnostic} and will be written to the default output.
 *
 * <p>A compiler tool has an associated standard file manager, which
 * is the file manager that is native to the tool (or built-in).  The
 * standard file manager can be obtained by calling {@linkplain
 * #getStandardFileManager getStandardFileManager}.
 *
 * <p>A compiler tool must function with any file manager as long as
 * any additional requirements as detailed in the methods below are
 * met.  If no file manager is provided, the compiler tool will use a
 * standard file manager such as the one returned by {@linkplain
 * #getStandardFileManager getStandardFileManager}.
 *
 * <p>An instance implementing this interface must conform to
 * <cite>The Java Language Specification</cite>
 * and generate class files conforming to
 * <cite>The Java Virtual Machine Specification</cite>.
 * The versions of these
 * specifications are defined in the {@linkplain Tool} interface.
 *
 * Additionally, an instance of this interface supporting {@link
 * javax.lang.model.SourceVersion#RELEASE_6 SourceVersion.RELEASE_6}
 * or higher must also support {@linkplain javax.annotation.processing
 * annotation processing}.
 *
 * <p>The compiler relies on two services: {@linkplain
 * DiagnosticListener diagnostic listener} and {@linkplain
 * JavaFileManager file manager}.  Although most classes and
 * interfaces in this package defines an API for compilers (and
 * tools in general) the interfaces {@linkplain DiagnosticListener},
 * {@linkplain JavaFileManager}, {@linkplain FileObject}, and
 * {@linkplain JavaFileObject} are not intended to be used in
 * applications.  Instead these interfaces are intended to be
 * implemented and used to provide customized services for a
 * compiler and thus defines an SPI for compilers.
 *
 * <p>There are a number of classes and interfaces in this package
 * which are designed to ease the implementation of the SPI to
 * customize the behavior of a compiler:
 *
 * <dl>
 *   <dt>{@link StandardJavaFileManager}</dt>
 *   <dd>
 *
 *     Every compiler which implements this interface provides a
 *     standard file manager for operating on regular {@linkplain
 *     java.io.File files}.  The StandardJavaFileManager interface
 *     defines additional methods for creating file objects from
 *     regular files.
 *
 *     <p>The standard file manager serves two purposes:
 *
 *     <ul>
 *       <li>basic building block for customizing how a compiler reads
 *       and writes files</li>
 *       <li>sharing between multiple compilation tasks</li>
 *     </ul>
 *
 *     <p>Reusing a file manager can potentially reduce overhead of
 *     scanning the file system and reading jar files.  Although there
 *     might be no reduction in overhead, a standard file manager must
 *     work with multiple sequential compilations making the following
 *     example a recommended coding pattern:
 *
 *     <pre>
 *       File[] files1 = ... ; // input for first compilation task
 *       File[] files2 = ... ; // input for second compilation task
 *
 *       JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();
 *       StandardJavaFileManager fileManager = compiler.getStandardFileManager(null, null, null);
 *
 *       {@code Iterable<? extends JavaFileObject>} compilationUnits1 =
 *           fileManager.getJavaFileObjectsFromFiles({@linkplain java.util.Arrays#asList Arrays.asList}(files1));
 *       compiler.getTask(null, fileManager, null, null, null, compilationUnits1).call();
 *
 *       {@code Iterable<? extends JavaFileObject>} compilationUnits2 =
 *           fileManager.getJavaFileObjects(files2); // use alternative method
 *       // reuse the same file manager to allow caching of jar files
 *       compiler.getTask(null, fileManager, null, null, null, compilationUnits2).call();
 *
 *       fileManager.close();</pre>
 *
 *   </dd>
 *
 *   <dt>{@link DiagnosticCollector}</dt>
 *   <dd>
 *     Used to collect diagnostics in a list, for example:
 *     <pre>
 *       {@code Iterable<? extends JavaFileObject>} compilationUnits = ...;
 *       JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();
 *       {@code DiagnosticCollector<JavaFileObject> diagnostics = new DiagnosticCollector<JavaFileObject>();}
 *       StandardJavaFileManager fileManager = compiler.getStandardFileManager(diagnostics, null, null);
 *       compiler.getTask(null, fileManager, diagnostics, null, null, compilationUnits).call();
 *
 *       for ({@code Diagnostic<? extends JavaFileObject>} diagnostic : diagnostics.getDiagnostics())
 *           System.out.format("Error on line %d in %s%n",
 *                             diagnostic.getLineNumber(),
 *                             diagnostic.getSource().toUri());
 *
 *       fileManager.close();</pre>
 *   </dd>
 *
 *   <dt>
 *     {@link ForwardingJavaFileManager}, {@link ForwardingFileObject}, and
 *     {@link ForwardingJavaFileObject}
 *   </dt>
 *   <dd>
 *
 *     Subclassing is not available for overriding the behavior of a
 *     standard file manager as it is created by calling a method on a
 *     compiler, not by invoking a constructor.  Instead forwarding
 *     (or delegation) should be used.  These classes makes it easy to
 *     forward most calls to a given file manager or file object while
 *     allowing customizing behavior.  For example, consider how to
 *     log all calls to {@linkplain JavaFileManager#flush}:
 *
 *     <pre>
 *       final  Logger logger = ...;
 *       {@code Iterable<? extends JavaFileObject>} compilationUnits = ...;
 *       JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();
 *       StandardJavaFileManager stdFileManager = compiler.getStandardFileManager(null, null, null);
 *       JavaFileManager fileManager = new ForwardingJavaFileManager(stdFileManager) {
 *           public void flush() throws IOException {
 *               logger.entering(StandardJavaFileManager.class.getName(), "flush");
 *               super.flush();
 *               logger.exiting(StandardJavaFileManager.class.getName(), "flush");
 *           }
 *       };
 *       compiler.getTask(null, fileManager, null, null, null, compilationUnits).call();</pre>
 *   </dd>
 *
 *   <dt>{@link SimpleJavaFileObject}</dt>
 *   <dd>
 *
 *     This class provides a basic file object implementation which
 *     can be used as building block for creating file objects.  For
 *     example, here is how to define a file object which represent
 *     source code stored in a string:
 *
 *     <pre>
 *       /**
 *        * A file object used to represent source coming from a string.
 *        {@code *}/
 *       public class JavaSourceFromString extends SimpleJavaFileObject {
 *           /**
 *            * The source code of this "file".
 *            {@code *}/
 *           final String code;
 *
 *           /**
 *            * Constructs a new JavaSourceFromString.
 *            * {@code @}param name the name of the compilation unit represented by this file object
 *            * {@code @}param code the source code for the compilation unit represented by this file object
 *            {@code *}/
 *           JavaSourceFromString(String name, String code) {
 *               super({@linkplain java.net.URI#create URI.create}("string:///" + name.replace('.','/') + Kind.SOURCE.extension),
 *                     Kind.SOURCE);
 *               this.code = code;
 *           }
 *
 *           {@code @}Override
 *           public CharSequence getCharContent(boolean ignoreEncodingErrors) {
 *               return code;
 *           }
 *       }</pre>
