Field Detail

### __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 org.python.core.packagecache.PackageManager __mgr__

  (Control) package manager whose hierarchy contains this java pkg.

Constructor Detail

### PyJavaPackage

    public PyJavaPackage(String name)

### PyJavaPackage

    public PyJavaPackage(String name,
                         String jarfile)

### PyJavaPackage

    public PyJavaPackage(String name,
                         org.python.core.packagecache.PackageManager mgr)

### PyJavaPackage

    public PyJavaPackage(String name,
                         org.python.core.packagecache.PackageManager mgr,
                         String jarfile)

Method Detail

### addPackage

    public PyJavaPackage addPackage(String name)

### addPackage

    public PyJavaPackage addPackage(String name,
                                    String jarfile)

### addClass

    public PyObject addClass(String name,
                             Class<?> c)

### addPlaceholders

    public void addPlaceholders(String classes)

  Add statically known classes.

  Parameters:
    `classes` - their names as comma-separated string

### __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`
