windowCount method
inherited
Buffers a number of values from the source Observable by count then
emits the buffer as a Stream and clears it, and starts a new buffer each
startBufferEvery values. If startBufferEvery is not provided,
then new buffers are started immediately at the start of the source
and when each buffer closes and is emitted.
Example
count is the maximum size of the buffer emitted
Observable.range(1, 4)
.windowCount(2)
.asyncMap((stream) => stream.toList())
.listen(print); // prints [1, 2], [3, 4] done!
Example
if startBufferEvery is 2, then a new buffer will be started
on every other value from the source. A new buffer is started at the
beginning of the source by default.
Observable.range(1, 5)
.bufferCount(3, 2)
.listen(print); // prints [1, 2, 3], [3, 4, 5], [5] done!
Implementation
Observable<Stream<T>> windowCount(int count, [int startBufferEvery = 0]) =>
transform(WindowCountStreamTransformer(count, startBufferEvery));
