Iterators
Python iterator support a highly flexible interface allowing:
- Direct exposure of a class' begin() and end() functions:
...
.def("__iter__", iterator<list_int>())- Creation of iterators from member functions...
...
.def("__iter__"
, range(&my_class::x_begin, &my_class::x_end))- ...and member data:
...
.def("__iter__"
, range(&std::pair<char*,char*>::first, &std::pair<char*,char*>::second))The ability to specify [http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/*checkout*/boost/boost/libs/python/doc/v2/CallPolicies.html CallPolicies], e.g. to prevent copying of heavyweight values:
...
.def("__iter__"
, range<return_value_policy<copy_non_const_reference> >(
&my_sequence<heavy>::begin
, &my_sequence<heavy>::end))
