Detailed Description

template<typename T1, typename T2, typename T3, typename T4>
class sensesp::Join4< T1, T2, T3, T4 >

Merge four producer values into a tuple.

Merges the connected producers' values into a tuple. The tuple is emitted once all producers have emitted a new value within max_age milliseconds.
