CPython function	Jython method
long intobject::PyInt_AsLong(register PyObject *op)	int PyObject.asInt()
PyObject* intobject::PyInt_FromString(char s, char *pend, int base)	PyObject PyObject.`__int__`()
Py_ssize_t intobject::PyInt_AsSsize_t(register PyObject *op)	int PyObject.`__int__`().asInt()
Py_ssize_t abstract::PyNumber_AsSsize_t(PyObject item, PyObject err)	int PyObject.asIndex(err)
int abstract.h::PyIndex_Check(PyObject *ob)	boolean PyObject.isIndex()

When using asInt, consider whether you want to ensure the original object is an instanceof PyInteger/PyLong prior to calling asInt on it. It’s common to do this check before calling asInt, but is not required – otherwise asInt will attempt to implicitly convert non int/longs via user defined __int__ methods.
