Types
Declarations
empty
visibility: public
type: Unit -> Stream a
Creates a new empty stream.
from
visibility: public
type: a -> Stream a
Creates a stream with a single element.
forEach
visibility: public
type: Stream a -> (a -> b) -> Unit
Runs function f for every element of this Stream, ignoring the result. Runtime: O(n)
toArray
visibility: public
type: Stream a -> Array Object
Collects this Stream into an Array.
size
visibility: public
type: Stream a -> Int64
Returns the size of this stream.
filter
visibility: public
type: (a -> Boolean) -> Stream a -> Stream a
Returns a stream of the elements that match the given predicate.
map
visibility: public
type: (a -> b) -> Stream a -> Stream b
Maps function f over all elements of this Stream returning a Stream. Runtime: O(n)
flatMap
visibility: public
type: (a -> Stream b) -> Stream a -> Stream b
Like map but it will flatten the resulting stream.
limit
visibility: public
type: Int64 -> Stream a -> Stream a
Returns a new stream with a limited number of elements.
skip
visibility: public
type: Int64 -> Stream a -> Stream a
Returns a stream with the first n elements skipped.
takeWhile
visibility: public
type: (a -> Boolean) -> Stream a -> Stream a
Takes elements from this stream while the predicates holds.
dropWhile
visibility: public
type: (a -> Boolean) -> Stream a -> Stream a
Drops elements from this stream while the predicates holds.
reduce
visibility: public
type: (a -> a -> a) -> Stream a -> Option a
Reduces this stream to a single value according to the reducing function.
reduceInit
visibility: public
type: (a -> a -> a) -> a -> Stream a -> a
Reduces this stream to a single value according to the reducing function.
