Parameters:

time - period

t - Time unit

Returns:

SequenceM that emits 1 element per time period

fixedDelay

default ReactiveSeq<T> fixedDelay(long l,
                                  java.util.concurrent.TimeUnit unit)

emit elements after a fixed delay

 
  SimpleTimer timer = new SimpleTimer();
  ReactiveSeq.of(1, 2, 3, 4, 5, 6)
             .fixedDelay(10000, TimeUnit.NANOSECONDS)

  //timer.getElapsedNanoseconds() > greaterThan(60000l)
 
 

Parameters:

l - time length in nanos of the delay

unit - for the delay

Returns:
