final class Accumulate[A, B] extends GraphStage[FlowShape[A, B]]

This stage emits folded values like scan, but the first element emitted is not the zero value but the result of applying the given function to the given zero value and the first pushed element.

A

input type

B

output type

@deprecated
Deprecated

(Since version 0.5) Use scan and drop(1) instead
