public boolean refersDirectlyTo(PyObject ob)

Implements org.python.core.Traverseproc.refersDirectlyTo.

Doc from org.python.core.Traverseproc.refersDirectlyTo.

Optional operation. Should only be implemented if it is more efficient than calling traverse(Visitproc, Object) with a visitproc that just watches out for ob. Must return false if ob is null.

public int traverse(Visitproc visit, Object arg)

Implements org.python.core.Traverseproc.traverse.

Doc from org.python.core.Traverseproc.traverse.

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.
