template<class Iterator >

DeepIterator<Iterator> deep_iterate

(

const Iterator &

i

)

Returns an input iterator from an iterator.

Supports two kinds of iterators:

Direct iterators, where given iterator i, i->deep_copy() returns a deep copy of the value; OR

Pair iterators (e.g., map::iterator), where given iterator i, i->second.deep_copy() returns a deep copy of the value.

In either case, the returned iterator behaves like the original, except restricted to input semantics, and the values are deep copies of the original values. Elements not deep copied (such as the key in a map's key-value pair) may be const references to the original instead of a copy.

Parameters

i	the iterator to mimic. The iterator will be copied internally.

Returns

the input iterator
