__findattr__

public PyObject __findattr__(String name)

Description copied from class: PyObject

A variant of the __findattr__ method which accepts a Java String as the name. By default, this method will call __findattr__(PyString name) with the appropriate args. The only reason to override this method is for performance. Warning: name must be an interned string!!!!!!!!

Overrides:

__findattr__ in class PyObject

Parameters:

name - the name to lookup in this namespace must be an interned string .

Returns:

the value corresponding to name or null if name is not found

See Also:

PyObject.__findattr__(PyString)

__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)

safeRepr

public String safeRepr()
                throws PyIgnoreMethodTag

Overrides:

safeRepr in class PyObject

Throws:

PyIgnoreMethodTag

toString

                              Properties postProperties,
                              String[] argv)

add_package

public static PyJavaPackage add_package(String n,
                                        String contents)

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 subdirectory are not made available to jython by this call. It only make the java package found ion the directory available. This call is mostly usefull if jython is embedded in an application that deals with its own classloaders. A servlet container is a very good example. Calling add_classdir("/WEB-INF/classes") makes the java packages in WEB-INF classes available to jython import. However the actual classloading is completely handled by the servlet container's context classloader.

add_extdir

public static void add_extdir(String directoryPath)

Add a .jar & .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 & .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.
