Detailed Description

template<class JBase_t, class JDerived_t>
struct JLANG::JObjectDemultiplexer< JBase_t, JDerived_t >

Auxiliary class for demultiplexing object outputs.

The template argument JDerived_t refers to a list of multiple object outputs which are processed in parallel.
The template argument JBase_t refers to a single object output which provides for a common interface to the multiple object outputs.

This class implements the JLANG::JObjectOutput interface.
