Detailed Description

template<typename K, typename V>
class ignite::thin::cache::query::QueryCursor< K, V >

Query cursor class template.

Both key and value types should be default-constructable, copy-constructable and assignable. Also BinaryType class template should be specialized for both types.

This class is implemented as a reference to an implementation so copying of this class instance will only create another reference to the same underlying object. Underlying object will be released automatically once all the instances are destructed.
