andThen

default FailableDoubleUnaryOperator<E> andThen(FailableDoubleUnaryOperator<E> after)

Returns a composed FailableDoubleUnaryOperator like DoubleUnaryOperator.andThen(DoubleUnaryOperator).

Parameters:

after - the operator to apply after this one.

Returns:

a composed FailableDoubleUnaryOperator like DoubleUnaryOperator.andThen(DoubleUnaryOperator).
