/**
 * Returns a composed {@link BiDoublePredicate} that first applies the {@code before} functions to its input, and
 * then applies this predicate to the result. If evaluation of either operation throws an exception, it is relayed
 * to the caller of the composed operation. This method is just convenience, to provide the ability to execute an
 * operation which accepts {@code double} input, before this primitive predicate is executed.
 *
 * @param before1 The first function to apply before this predicate is applied
 * @param before2 The second function to apply before this predicate is applied
 * @return A composed {@code BiDoublePredicate} that first applies the {@code before} functions to its input, and
 * then applies this predicate to the result.
 * @throws NullPointerException If given argument is {@code null}

 * double}./*from w ww  . j  a  v a  2s.  c om*/
