• __findattr_ex__

  public PyObject __findattr_ex__(String name)

  Description copied from class: PyObject

  Attribute lookup hook. If the attribute is not found, null may be returned or a Py.AttributeError can be thrown, whatever is more correct, efficient and/or convenient for the implementing class. Client code should use PyObject.__getattr__(String) or PyObject.__findattr__(String). Both methods have a clear policy for failed lookups.

  Overrides:

  __findattr_ex__ in class PyObject

  Returns:

  The looked up value. May return null if the attribute is not found

• __setattr__

  public void __setattr__(String name, PyObject value)

  Description copied from class: PyObject

  A variant of the __setattr__ method which accepts a String as the key. This String must be interned.

  Overrides:

  __setattr__ in class PyObject

  Parameters:

  name - the name whose value will be set - must be an interned string .

  value - the value to set this name to

  See Also:

  • PyObject.__setattr__(PyString, PyObject)

• __delattr__

  public void __delattr__(String name)

  Description copied from class: PyObject

  A variant of the __delattr__ method which accepts a String as the key. This String must be interned. By default, this will call __delattr__(PyString name) with the appropriate args. The only reason to override this method is for performance.

  Overrides:

  __delattr__ in class PyObject

  Parameters:

  name - the name which will be removed - must be an interned string .

  See Also:

  • PyObject.__delattr__(PyString)

• setCurrentWorkingDir

  public void setCurrentWorkingDir(String path)

  Change the current working directory to the specified path. path is assumed to be absolute and canonical (via os.path.realpath).

  public String getCurrentWorkingDir()

  Return a string representing the current working directory.

  Returns:

  a path String

  a resolved path String

• getPathLazy

  public static String getPathLazy(String path)

  Resolve a path. Returns the full path taking the current working directory into account. Like getPath but called statically. The current PySystemState is only consulted for the current working directory when it's necessary (when the path is relative).

  Parameters:

  path - a path String

  Returns:

  a resolved path String

• getFile

  public File getFile(String path)

  Resolve a path, returning a File, taking the current working directory into account.

  Parameters:

  path - a path String

  a resolved File

  Throws:

  PyIgnoreMethodTag

  Windows	win32
  Windows/Cygwin	cygwin
  Mac OS X	darwin
  OS/2	os2
  OS/2 EMX	os2emx
  RiscOS	riscos
  AtheOS	atheos

• add_package

  public static PyJavaPackage add_package(String n)

• add_classdir

  public static void add_classdir(String directoryPath)

  Add a classpath directory to the list of places that are searched for java packages.

  Note. Classes found in directory and sub-directory are not made available to jython by this call. It only makes the java package found in the directory available. This call is mostly useful if jython is embedded in an application that deals with its own class loaders. A servlet container is a very good example. Calling add_classdir("<context>/WEB-INF/classes") makes the java packages in WEB-INF classes available to jython import. However the actual class loading is completely handled by the servlet container's context classloader.

• add_extdir

  public static void add_extdir(String directoryPath)

  Add a .jar and .zip directory to the list of places that are searched for java .jar and .zip files. The .jar and .zip files found will not be cached.

  Note. Classes in .jar and .zip files found in the directory are not made available to jython by this call. See the note for add_classdir(dir) for more details.

  Parameters:

  directoryPath - The name of a directory.

  See Also:

  • add_classdir(java.lang.String)

• add_extdir

  public static void add_extdir(String directoryPath, boolean cache)

  Add a .jar and .zip directory to the list of places that are searched for java .jar and .zip files.

  Note. Classes in .jar and .zip files found in the directory are not made available to jython by this call. See the note for add_classdir(dir) for more details.

  Parameters:

  directoryPath - The name of a directory.

  cache - Controls if the packages in the zip and jar file should be cached.

  See Also:

  • add_classdir(java.lang.String)

• exit

  public static void exit(PyObject status)

  Exit a Python program with the given status.

  Parameters:

  status - the value to exit with

  Throws:

  PyException - SystemExit always throws this exception. When caught at top level the program will exit.

• exit

  public static void exit()

  Exit a Python program with the status 0.

  Specified by:

  close in interface AutoCloseable

  Specified by:

  close in interface Closeable

• getSystemVersionString

  public static String getSystemVersionString()

  Attempt to find the OS version. The mechanism on Windows is to extract it from the result of cmd.exe /C ver, and otherwise (assumed Unix-like OS) to use uname -v</code>.

• traverse

  public int traverse(Visitproc visit, Object arg)

  Description copied from interface: Traverseproc

  Traverses all directly contained PyObjects. Like in CPython, arg must be passed unmodified to visit as its second parameter. If Visitproc.visit(PyObject, Object) returns nonzero, this return value must be returned immediately by traverse. Visitproc.visit(PyObject, Object) must not be called with a null PyObject-argument.

  Specified by:

  traverse in interface Traverseproc

• refersDirectlyTo

  public boolean refersDirectlyTo(PyObject ob)

  Description copied from interface: Traverseproc

  Optional operation. Should only be implemented if it is more efficient than calling Traverseproc.traverse(Visitproc, Object) with a visitproc that just watches out for ob. Must return false if ob is null.

  Specified by:

  refersDirectlyTo in interface Traverseproc
