Detailed Description

template<class T>
class JniProxyIter< T >

JniProxyIter is used to access a JniProxy by reference.

Instances are returned by generated accessor methods (for either non-primitive type attributes or association ends). When the declared cardinality is 0..1, the returned iter may be singular. When the declared cardinality is 1..1, the returned iter will never be singular.

When the returned iter references a collection (either a multi-valued attribute or an association end with cardinality 0..n), it behaves as a forward iterator via operator++. It becomes singular when the collection is exhausted.
