Field Details
- __name__
  
  public String __name__
- __dict__
  
  public PyStringMap __dict__
- clsSet
  
  public PyStringMap clsSet
  
  Its keys are the names of statically known classes. E.g. from jars pre-scan.
- __file__
  
  public String __file__
- __mgr__
  
  public PackageManager __mgr__
  
  (Control) package manager whose hierarchy contains this java pkg
Constructor Details
- PyJavaPackage
  
  public PyJavaPackage(String name)
- PyJavaPackage
  
  public PyJavaPackage(String name, String jarfile)
- PyJavaPackage
  
  public PyJavaPackage(String name, PackageManager mgr)
- PyJavaPackage
  
  public PyJavaPackage(String name, PackageManager mgr, String jarfile)
Method Details
- addPackage
  
  public PyJavaPackage addPackage(String name)
- addPackage
  
  public PyJavaPackage addPackage(String name, String jarfile)
  
  From a dotted package name a.b.c interpreted relative to this package t, ensure that a is in the dictionary of t and then recursively process the remainder b.c relative to a, finally returning the PyJavaPackage(java.lang.String, org.python.core.packagecache.PackageManager, java.lang.String) of t.a.b.c. In the case where the initial package name is just a, no dots, the method simply ensures a is entered in t, and returns the PyJavaPackage of t.a.
  
  Parameters:
  
  name - a package name
  
  jarfile - becomes the __file__ attribute
  
  Returns:
  
  the PyJavaPackage of the package named
- addClass
  
  public PyObject addClass(String name, Class<?> c)
- addPlaceholders
  
  public void addPlaceholders(Collection<String> classes)
  
  Add the classes named to this package, but with only a placeholder value. These names are statically known, typically from processing JAR files on the class path.
  
  Parameters:
  
  classes - the names as strings
- __dir__
  
  public PyObject __dir__()
  
  Description copied from class: PyObject
  
  Equivalent to the standard Python __dir__ method.
  
  Overrides:
  
  __dir__ in class PyObject
  
  Returns:
  
  a list of names defined by this object.
- fillDir
  
  public PyObject fillDir()
  
  Used for 'from xyz import *', dynamically dir pkg filling up __dict__. It uses PackageManager.doDir(org.python.core.PyJavaPackage, boolean, boolean) implementation furnished by the control package manager with instantiate true. The package manager should load classes with addClass(java.lang.String, java.lang.Class<?>) in the package.
  
  Returns:
  
  list of member names
- __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 attr, 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:
  
  attr - 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)
- toString
  
  public String toString()
  
  Overrides:
  
  toString in class PyObject
- 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
