Creates intermediate state and collects all incoming signals in reversed order until some data appear on the trigger. Then clears the state and returns collected data in a single list.

Creates intermediate state and collects all incoming signals in direct order until some data appear on the trigger. Then clears the state and returns collected data in a single list.

Saves incoming signals to internal state. The previous value is replaced with the new one. When a signal appears on the trigger contact the current remembered value

in1.lastJoinUntil(in2).map{ case (data1, data2) => }

if there were no input, then the trigger signal do not appear on the output

JOINs two signals.

Creates intermediate state and collects all incoming signals from the source contact until some data appear on the trigger. Then clears the state and returns collected data in a single list together with the trigger signal.

in1.prependUntil(in2).map{ case (list1, data2) => ... }

Creates a state for temporary storing the value from the current contact.

A kind of a latch.

for all trigger signals that appear during latch delay the join is successful. If nothing has been remembered, then nothing appears on the output.

The latched value is cleared automatically after the given delay. This is better than lastJoinUntil when trigger do not appear in our timeslot. The remembered value is automatically removed anyway.
