When the Jar is created, it scans the file and builds a directory of the Jar entries. Inner Class :static class ZipStreamImpl extends StreamImpl Inner Class :static class JarDepend extends CachedDependency implements PersistentDependency Inner Class :static class JarDigestDepend implements PersistentDependency Method Summary public  boolean canRead(String path)      Readable if the jar is readable and the path refers to a file. public  boolean canWrite(String path)      Can't write to jars. public  void clearCache()      Clears any cached JarFile. public static  void clearJarCache()      Clears all the cached files in the jar. public  void close()      static  Jar create(Path backing)      Return a Jar for the path. public static  PersistentDependency createDepend(Path backing)      Return a Jar for the path. public static  PersistentDependency createDepend(Path backing, long digest)      Return a Jar for the path. public  boolean equals(Object o)      public  boolean exists(String path)      Returns true if the entry exists in the jar.  Path getBacking()      Returns the backing path. public  Certificate[] getCertificates(String path)      Returns any certificates. public  PersistentDependency getDepend()      Returns the dependency. static  Jar getJar(Path backing)      Return a Jar for the path. public  long getLastModified(String path)      Returns the length of the entry in the jar file. public  long getLength(String path)      Returns the length of the entry in the jar file. public  Manifest getManifest()      Returns true if the entry is a file in the jar. public  boolean isDirectory(String path)      Returns true if the entry is a directory in the jar. public  boolean isFile(String path)      Returns true if the entry is a file in the jar. public  String[] list(String path)      Lists all the files in this directory. public  StreamImpl openReadImpl(Path path)      Opens a stream to an entry in the jar. public  void removeEvent()      public  String toString()      Method Detail canRead public boolean canRead(String path)(Code) Readable if the jar is readable and the path refers to a file. canWrite public boolean canWrite(String path)(Code) Can't write to jars. clearCache public void clearCache()(Code) Clears any cached JarFile. clearJarCache public static void clearJarCache()(Code) Clears all the cached files in the jar. Needed to avoid some windows NT issues. close public void close()(Code) create static Jar create(Path backing)(Code) Return a Jar for the path. If the backing already exists, return the old jar. createDepend public static PersistentDependency createDepend(Path backing)(Code) Return a Jar for the path. If the backing already exists, return the old jar. createDepend public static PersistentDependency createDepend(Path backing, long digest)(Code) Return a Jar for the path. If the backing already exists, return the old jar. equals public boolean equals(Object o)(Code) exists public boolean exists(String path)(Code) Returns true if the entry exists in the jar. Parameters:   path - the path name inside the jar. getBacking Path getBacking()(Code) Returns the backing path. getCertificates public Certificate[] getCertificates(String path)(Code) Returns any certificates. getDepend public PersistentDependency getDepend()(Code) Returns the dependency. getJar static Jar getJar(Path backing)(Code) Return a Jar for the path. If the backing already exists, return the old jar. getLastModified public long getLastModified(String path)(Code) Returns the length of the entry in the jar file. Parameters:   path - full path to the jar entry the length of the entry getLength public long getLength(String path)(Code) Returns the length of the entry in the jar file. Parameters:   path - full path to the jar entry the length of the entry getManifest public Manifest getManifest() throws IOException(Code) Returns true if the entry is a file in the jar. Parameters:   path - the path name inside the jar. isDirectory public boolean isDirectory(String path)(Code) Returns true if the entry is a directory in the jar. Parameters:   path - the path name inside the jar. isFile public boolean isFile(String path)(Code) Returns true if the entry is a file in the jar. Parameters:   path - the path name inside the jar. list public String[] list(String path) throws IOException(Code) Lists all the files in this directory. openReadImpl public StreamImpl openReadImpl(Path path) throws IOException(Code) Opens a stream to an entry in the jar. Parameters:   path - relative path into the jar. removeEvent public void removeEvent()(Code) toString public String toString()(Code) Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
