FlowOperations<Tuple<A,
,B>, ZippedFlow<A, B>> Iterable<Tuple<A,

The result of the
Flow.zipWith(Flow)
method (or created from a Map via F.zippedFlow(Map)
), a Flow of
combined Tuple
values (that can be deconstructed, eventually, using unzip()
).- Since:

Method Details
-
mapTuples
Mapping for zipped flows; a mapper is used to map tuples of this zipped flow into new tuples with a new type, forming the resulting zipped flow. This is a lazy operation. -
unzip
A ZippedFlow is a Flow of Tuples; this inverts that, splitting each Tuple into a Flow of elements, then assembling the result as a Tuple of two values. This is a lazy operation.- Returns:
- two flows of unzipped Tuples
-
firsts
Returns a flow of the first values of the tuples of the zipped flow. This is a lazy operation. -
seconds
Returns a flow of the second values of the tuples of the zipped flow. This is a lazy operation. -
filterOnFirst
Filters the tuples in the zipped flow by applying a predicate to the first value in each tuple. This is a lazy operation. -
filterOnSecond
Filters the tuples in the zipped flow by applying a predicate to the second value in each tuple. This is a lazy operations. -
removeOnFirst
Removes tuples from the zipped flow by applying a predicate to the first value in each tuple. This is a lazy operation. -
removeOnSecond
Removes tuples from the zipped flow by applying a predicate to the second value in each tuple. This is a lazy operations. -
toMap
Constructs a HashMap by converting the tuples of the zipped flow into keys (first tuple value) and values (second tuple value).
