Detailed Description

template<class JDerived_t, class JBase_t = typename JBaseClass<JDerived_t>::data_type>
class JLANG::JObjectMultiplexer< JDerived_t, JBase_t >

Auxiliary class for multiplexing object iterators.

The template argument JDerived_t refers to a list of multiple object iterators which are sequentially processed.
The template argument JBase_t refers to a single object iterator which provides for a common interface to the multiple object iterators.

This class implements the JLANG::JObjectIterator interface.
