Uses of Interface
java.util.function.DoubleUnaryOperator
Package
Description
Functional interfaces provide target types for lambda expressions
and method references.
Classes to support functional-style operations on streams of elements, such
as map-reduce transformations on collections.

function to an initial element, conditioned on satisfying the givenhasNext
predicate.static DoubleStream
DoubleStream.iterate(double seed, DoubleUnaryOperator f)
Returns an infinite sequential orderedDoubleStream
produced by iterative application of a functionf
to an initial elementseed
, producing aStream
consisting ofseed
,f(seed)
,f(f(seed))
, etc.DoubleStream.map(DoubleUnaryOperator mapper)
