public AbstractReference(PyType subType,

                         PyObject callback)
```
- Method Detail
  - equals
```
public boolean equals(java.lang.Object ob_other)
```
    Description copied from class: PyObject
    
    Should almost never be overridden. If overridden, it is the subclasses responsibility to ensure that a.equals(b) == true iff cmp(a,b) == 0
    
    Overrides:
    
    equals in class PyObject
  - hasCallback
```
public boolean hasCallback()
```
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class PyObject
  - __eq__
```
public PyObject __eq__(PyObject other)
```
    Description copied from class: PyObject
    
    Equivalent to the standard Python __eq__ method.
    
    Overrides:
    
    __eq__ in class PyObject
    
    Parameters:
    
    other - the object to compare this with.
    
    Returns:
    
    the result of the comparison.
  - __ne__
```
public PyObject __ne__(PyObject other)
```
    Description copied from class: PyObject
    
    Equivalent to the standard Python __ne__ method.
    
    Overrides:
    
    __ne__ in class PyObject
    
    Parameters:
    
    other - the object to compare this with.
    
    Returns:
    
    the result of the comparison.
  - traverse
```
public int traverse(Visitproc visit,
                    java.lang.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
