The type of the first random engine.


The shift count for the first random engine.


The type of the second random engine.


The shift count for the second random engine.

The template class decribes a compound engine that produces values by combining values produced by two engines. The engine's state is the state of stored_eng1 followed by the state of stored_eng2.
