Constructor Detail

• JarFileSystem

  public JarFileSystem​()

  Default constructor.

  Most module code should never create an instance of this class directly. Use FileUtil.getArchiveRoot(FileObject) instead.

• JarFileSystem

  public JarFileSystem​(java.io.File jar)
                throws java.io.IOException

  Creates new JAR for a given JAR file. This constructor behaves basically like:

   JarFileSystem fs = new JarFileSystem();
   fs.setJarFile(jar);
   

  but it is more effective in some situations. It does not open and read the content of the jar file immediately. Instead it waits until somebody asks for resources from inside the JAR.

  Parameters:

  jar - location of the JAR file

  Throws:

  java.io.IOException

  Since:

  7.34

Method Detail

• createReference

  protected <T extends FileObject> java.lang.ref.Reference<T> createReference​(T fo)

  Description copied from class: AbstractFileSystem
  Creates Reference. In FileSystem, which subclasses AbstractFileSystem, you can overload method createReference(FileObject fo) to achieve another type of Reference (weak, strong etc.)

  Overrides:

  createReference in class AbstractFileSystem

  Parameters:

  fo - is FileObject. It`s reference yourequire to get.

  Returns:

  Reference to FileObject

• getManifest

  public java.util.jar.Manifest getManifest​()

  Get the JAR manifest. It will be lazily initialized.

  Returns:

  parsed manifest file for this archive

• setJarFile

  public void setJarFile​(java.io.File aRoot)
                  throws java.io.IOException,
                         java.beans.PropertyVetoException

  Set name of the ZIP/JAR file.

  Parameters:

  aRoot - path to new ZIP or JAR file

  Throws:

  java.io.IOException - if the file is not valid

  java.lang.IllegalArgumentException - if the file is not normalized

  java.beans.PropertyVetoException

• getJarFile

  public java.io.File getJarFile​()

  Get the file path for the ZIP or JAR file.

  Returns:

  the file path

• getDisplayName

  public java.lang.String getDisplayName​()

  Description copied from class: FileSystem
  Provides a name for the system that can be presented to the user.

  This call should never be used to attempt to identify the file root of the filesystem. On some systems it may happen to look the same but this is a coincidence and may well change in the future. Either check whether you are working with a LocalFileSystem or similar implementation and use LocalFileSystem.getRootDirectory(); or better, try FileUtil.toFile(org.openide.filesystems.FileObject) which is designed to do this correctly.

  Note: for most purposes it is probably a bad idea to use this method. Instead look at FileUtil.getFileDisplayName(org.openide.filesystems.FileObject).

  Specified by:

  getDisplayName in class AbstractFileSystem

  Returns:

  user presentable name of the filesystem

• isReadOnly

  public boolean isReadOnly​()

  This filesystem is read-only.

  Specified by:

  isReadOnly in class FileSystem

  Returns:

  true

• removeNotify

  public void removeNotify​()

  Description copied from class: FileSystem
  Notifies this filesystem that it has been removed from the repository. Concrete filesystem implementations could perform clean-up here. The default implementation does nothing.

  Note that this method is advisory and serves as an optimization to avoid retaining resources for too long etc. Filesystems should maintain correct semantics regardless of whether and when this method is called.

  Overrides:

  removeNotify in class FileSystem
