PairwiseStreamTransformer<T> class

Emits the n-th and n-1th events as a pair..

Rx.range(1, 4)
  .pairwise()
  .listen(print); // prints [1, 2], [2, 3], [3, 4]

Constructors

PairwiseStreamTransformer(): Constructs a StreamTransformer which buffers events into pairs as a List.

closeWindowWhen → bool Function(List<T> queue): Predicate which determines when the current window should close
final, inherited
dispatchOnClose → bool: Toggle to prevent, or allow the final set of events to be dispatched when the source Stream closes
final, inherited
hashCode → int: The hash code for this object. [...]
read-only, inherited
ignoreEmptyWindows → bool: Toggle to prevent, or allow windows that contain no events to be dispatched
final, inherited
onWindowEnd → Iterable<T> Function(List<T> queue): Handler which fires when the window closes
final, inherited
onWindowStart → Iterable<T> Function(T event): Handler which fires when the window opens
final, inherited
runtimeType → Type: A representation of the runtime type of the object.

startBufferEvery → int: Used to skip an amount of events
final, inherited
strategy → WindowStrategy: Determines how the window is created
final, inherited
windowStreamFactory → Stream Function(T event): Factory method used to create the Stream which will be buffered
