public class FieldNameIterator extends PyObject implements Traverseproc
str._formatter_field_name_split() and
 unicode._formatter_field_name_split(). The function
 _formatter_field_name_split() returns a pair (tuple) consisting of a head element
 and an instance of this iterator. The constructor of this class effectively implements that
 function, since as well as "being" the iterator, the object has an extra method head()
 to return the required first member of the pair.| Modifier and Type | Class and Description |

 for. |

 The object is used from PyUnicode and from PyString, and we have to signal which it is, so
 that returned values may match in type.fieldName - the field name as UTF-16bytes - true if elements returned should be PyString, else PyUnicodepublic FieldNameIterator(PyString fieldNameObject)
fieldNameObject - public PyObject __iter__()
PyObjectIf a PyObject subclass should support iteration based in the __finditem__() method, it must supply an implementation of __iter__() like this:
 public PyObject __iter__() {
     return new PySequenceIter(this);
 }
 
 When iterating over a python sequence from java code, it should be done with code like this:
 
 for (PyObject item : seq.asIterable()) {
     // Do somting with item
 }

 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.
