Constructors
Declared in <bslstl_list.h>
Create a singular iterator (i.e., one that cannot be incremented, decremented, or dereferenced until assigned a non-singular value).
List_Iterator();Create an iterator that has the same value as the specified other iterator. If the (template parameter) type VALUE is not const-qualified, then this constructor is the copy constructor; otherwise, the copy constructor is implicitly generated. Note that this method is marked "IMPLICIT" in case it is not the copy constructor.
List_Iterator(NcIter const& other);Create an iterator that references the value pointed to by the specified nodePtr. If 0 == nodePtr the iterator will be singular.
