public static final PyType TYPE
```
- Method Detail
  - byref
```
public PyObject byref(PyObject offset)
```
    Wraps up this object in a pointer that can be passed to native code. The byref() return value cannot be used as anything other than a parameter.
    
    Returns:
    
    A ByReference instance pointing to this object's native memory.
  - pointer
```
public PyObject pointer(PyObject pytype)
```
  - address
```
public PyObject address()
```
  - getReferenceMemory
```
public final DirectMemory getReferenceMemory()
```
    Returns the memory used when creating a reference to this instance. e.g. via byref(obj)
    
    Returns:
    
    The reference memory for this object
  - getContentMemory
```
public Memory getContentMemory()
```
  - 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
