Field Detail

• archiveEntries

  protected java.util.HashMap<java.lang.String,java.util.jar.JarEntry> archiveEntries

• archiveLock

  protected final java.lang.Object archiveLock

Constructor Detail

• AbstractArchiveResourceSet

  public AbstractArchiveResourceSet()

Method Detail

• setBaseUrl

  protected final void setBaseUrl(java.net.URL baseUrl)

• getBaseUrl

  public final java.net.URL getBaseUrl()

  Description copied from interface: WebResourceSet
  Obtain the base URL for this set of resources. One of the uses of this is to grant read permissions to the resources when running under a security manager.

• getBaseUrlString

  protected final java.lang.String getBaseUrlString()

• list

  public final java.lang.String[] list(java.lang.String path)

  Description copied from interface: WebResourceSet
  Obtain the list of the names of all of the files and directories located in the specified directory.

  Parameters:

  path - The path for the resource of interest relative to the root of the web application. It must start with '/'.

  Returns:

  The list of resources. If path does not refer to a directory then a zero length array will be returned.

• listWebAppPaths

  public final java.util.Set<java.lang.String> listWebAppPaths(java.lang.String path)

  Description copied from interface: WebResourceSet
  Obtain the Set of the web applications pathnames of all of the files and directories located in the specified directory. Paths representing directories will end with a "/" character.

  Parameters:

  path - The path for the resource of interest relative to the root of the web application. It must start with '/'.

  Returns:

  The Set of resources. If path does not refer to a directory then an empty set will be returned.

• getArchiveEntries

  protected abstract java.util.HashMap<java.lang.String,java.util.jar.JarEntry> getArchiveEntries(boolean single)

  Obtain the map of entries in the archive. May return null in which case getArchiveEntry(String) should be used.

  Parameters:

  single - Is this request being make to support a single lookup? If false, a map will always be returned. If true, implementations may use this as a hint in determining the optimum way to respond.

  Returns:

  The archives entries mapped to their names or null if getArchiveEntry(String) should be used.

• getArchiveEntry

  protected abstract java.util.jar.JarEntry getArchiveEntry(java.lang.String pathInArchive)

  Obtain a single entry from the archive. For performance reasons, getArchiveEntries(boolean) should always be called first and the archive entry looked up in the map if one is returned. Only if that call returns null should this method be used.

  Parameters:

  pathInArchive - The path in the archive of the entry required

  Returns:

  The specified archive entry or null if it does not exist

• mkdir

  public final boolean mkdir(java.lang.String path)

  Description copied from interface: WebResourceSet
  Create a new directory at the given path.

  Parameters:

  path - The path for the new resource to create relative to the root of the web application. It must start with '/'.

  Returns:

  true if the directory was created, otherwise false

• write

  public final boolean write(java.lang.String path,
              java.io.InputStream is,
              boolean overwrite)

  Description copied from interface: WebResourceSet
  Create a new resource at the requested path using the provided InputStream.

  Parameters:

  path - The path to be used for the new Resource. It is relative to the root of the web application and must start with '/'.

  is - The InputStream that will provide the content for the new Resource.

  overwrite - If true and the resource already exists it will be overwritten. If false and the resource already exists the write will fail.

  Returns:

  true if and only if the new Resource is written

• getResource

  public final WebResource getResource(java.lang.String path)

  Description copied from interface: WebResourceSet
  Obtain the object that represents the resource at the given path. Note the resource at that path may not exist.

  Parameters:

  path - The path for the resource of interest relative to the root of the web application. It must start with '/'.

  Returns:

  The object that represents the resource at the given path

• isMultiRelease

  protected abstract boolean isMultiRelease()

• createArchiveResource

  protected abstract WebResource createArchiveResource(java.util.jar.JarEntry jarEntry,
                                  java.lang.String webAppPath,
                                  java.util.jar.Manifest manifest)

• isReadOnly

  public final boolean isReadOnly()

  Description copied from interface: WebResourceSet
  Obtains the current value of the read-only setting for this set of resources.

  Returns:

  true if this set of resources is configured to be read-only, otherwise false

• setReadOnly

  public void setReadOnly(boolean readOnly)

  Description copied from interface: WebResourceSet
  Configures whether or not this set of resources is read-only.

  Parameters:

  protected java.util.jar.JarFile openJarFile()
                                       throws java.io.IOException

  Throws:

  java.io.IOException

• closeJarFile

  protected void closeJarFile()

• gc

  public void gc()

  Description copied from interface: WebResourceSet
  Implementations may cache some information to improve performance. This method triggers the clean-up of those resources.
