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