INTERNAL lookup for name through mro objects' dicts

Parameters:

name - attribute name (must be interned)

Returns:

found object or null

                             PyObject[] where)

fromClass

public static PyType fromClass(java.lang.Class c)

fastGetDict

public PyObject fastGetDict()

Description copied from class: PyObject

xxx implements where meaningful

Overrides:

fastGetDict in class PyObject

Returns:

internal object per instance dict or null

See Also:

PyObject.fastGetDict()

getDict

public PyObject getDict()

Description copied from class: PyObject

xxx implements where meaningful

Overrides:

getDict in class PyObject

Returns:

internal object __dict__ or null

setDict

public void setDict(PyObject newDict)

Overrides:

setDict in class PyObject

delDict

public void delDict()

Overrides:

delDict in class PyObject

__tojava__

public java.lang.Object __tojava__(java.lang.Class c)

Description copied from class: PyObject

Equivalent to the Jython __tojava__ method. Tries to coerce this object to an instance of the requested Java class. Returns the special object Py.NoConversion if this PyObject can not be converted to the desired Java class.

Overrides:

__tojava__ in class PyObject

Parameters:

c - the Class to convert this PyObject to.

getModule

public PyObject getModule()

getNumSlots

public int getNumSlots()

getFullName

public java.lang.String getFullName()

toString

public java.lang.String toString()

Overrides:

toString in class PyObject

__findattr__

public PyObject __findattr__(java.lang.String name)

Description copied from class: PyObject

A variant of the __findattr__ method which accepts a Java String as the name. 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__(java.lang.String)

__delattr__

public void __delattr__(java.lang.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__(java.lang.String)

__setattr__

public void __setattr__(java.lang.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__(java.lang.String, org.python.core.PyObject)

public java.lang.String safeRepr()
                          throws PyIgnoreMethodTag

Overrides:

safeRepr in class PyObject

Throws:

PyIgnoreMethodTag

See Also:

PyObject.safeRepr()

__call__

public PyObject __call__(PyObject[] args,
                         java.lang.String[] keywords)

Description copied from class: PyObject

The basic method to override when implementing a callable object. The first len(args)-len(keywords) members of args[] are plain arguments. The last len(keywords) arguments are the values of the keyword arguments.

Overrides:

__call__ in class PyObject

Parameters:

args - all arguments to the function (including keyword arguments).

keywords - the keywords used for all keyword arguments.
