com.sun.tools.javac.file.ZipFileIndex

This class implements the building of index of a zip archive and access to its context. It also uses a prebuilt index if available. It supports invocations where it will serialize an optimized zip index file to disk. In order to use a secondary index file, set "usezipindex" in the Options object when JavacFileManager is invoked. (You can pass "-XDusezipindex" on the command line.) Location where to look for/generate optimized zip index files can be provided using " {@code -XDcachezipindexdir=}". If this flag is not provided, the default location is the value of the "java.io.tmpdir" system property. If "-XDwritezipindexfiles" is specified, there will be new optimized index file created for each archive, used by the compiler for compilation, at the location specified by the "cachezipindexdir" option. If system property nonBatchMode option is specified the compiler will use timestamp checking to reindex the zip files if it is needed. In batch mode the timestamps are not checked and the compiler uses the cached indexes.

This is NOT part of any supported API. If you write code that depends on this, you do so at your own risk. This code and its internal interfaces are subject to change or deletion without notice.

        JarFile j = new JarFile(rt_jar);
        JarEntry je = j.getJarEntry(TEST_ENTRY_NAME.getPath());
        long jarEntryTime = je.getTime();


        ZipFileIndexCache zfic = ZipFileIndexCache.getSharedInstance();
        ZipFileIndex zfi = zfic.getZipFileIndex(rt_jar, null, false, null, false);
        long zfiTime = zfi.getLastModified(TEST_ENTRY_NAME);


        check(je, jarEntryTime, zfi + ":" + TEST_ENTRY_NAME.getPath(), zfiTime);


        Context context = new Context();
        JavacFileManager fm = new JavacFileManager(context, false, null);


        JarFile j = new JarFile(rt_jar);
        JarEntry je = j.getJarEntry(TEST_ENTRY_NAME.getPath());
        long jarEntryTime = je.getTime();


        ZipFileIndex zfi =
                ZipFileIndex.getZipFileIndex(rt_jar, null, false, null, false);
        long zfiTime = zfi.getLastModified(TEST_ENTRY_NAME);


        check(je, jarEntryTime, zfi + ":" + TEST_ENTRY_NAME.getPath(), zfiTime);
