static LongUnaryOperator |
LongUnaryOperators.andThen(LongUnaryOperator this_,
LongUnaryOperator after)
Returns a composed operator that first applies the
this_ operator to
its input, and then applies the after operator to the result. |
static LongUnaryOperator |
LongUnaryOperators.compose(LongUnaryOperator this_,
LongUnaryOperator before)
Returns a composed operator that first applies the
before
operator to its input, and then applies the this_ operator to the result. |
static LongUnaryOperator |
LongUnaryOperators.identity()
Returns a unary operator that always returns its input argument.

static LongStream |
LongStreams.iterate(long seed,
LongUnaryOperator f)
Returns an infinite sequential ordered
LongStream produced by iterative
application of a function f to an initial element seed ,
producing a Stream consisting of seed , f(seed) ,
f(f(seed)) , etc. |
LongStream |
LongStream.map(LongUnaryOperator mapper)
Returns a stream consisting of the results of applying the given
function to the elements of this stream.
