    • fromBiFunction

      @Nonnull public static <T, U> BiPredicate<T,U> fromBiFunction(@Nonnull BiFunction<? super T,? super U,Boolean> function, @Nonnull BiPredicate<T,U> defValue)
      Creates a BiPredicate that applies a BiFunction to inputs and returns its result, or a default value if null.
      Type Parameters:
      T - type of function input
      U - type of function input
      Parameters:
      function - function to apply to inputs
      defValue - default predicate to apply if function returns null
      Returns:
      a BiPredicate adapter

    • alwaysTrue

      @Nonnull public static <T, U> BiPredicate<T,U> alwaysTrue()
      Returns a BiPredicate that always evaluates to true.
      Type Parameters:
      T - first argument type
      U - second argument type
      Returns:
      the conforming BiPredicate
      Since:
      9.1.0

    • alwaysFalse

      @Nonnull public static <T, U> BiPredicate<T,U> alwaysFalse()
      Returns a BiPredicate that always evaluates to false.
      Type Parameters:
      T - first argument type
      U - second argument type
      Returns:
      the conforming BiPredicate
      Since:
      9.1.0

    • not

      @Nonnull public static <T, U> BiPredicate<T,U> not(@Nonnull BiPredicate<? super T,? super U> predicate)
      Returns a BiPredicate that evaluates to true if the given BiPredicate evaluates to false.
      Type Parameters:
      T - predicate input type
      U - predicate input type
      Parameters:
      predicate - the predicate to negate
      Returns:
      the negated BiPredicate

    • and

      @Nonnull public static <T, U> BiPredicate<T,U> and(@Nonnull Iterable<? extends BiPredicate<? super T,? super U>> components)
      Returns a BiPredicate that evaluates to true if each of its components evaluates to true. The components are evaluated in order, and evaluation will be "short-circuited" as soon as a false BiPredicate is found. It defensively copies the iterable passed in, so future changes to it won't alter the behavior of this BiPredicate. If components is empty, the returned BiPredicate will always evaluate to true.
      Type Parameters:
      T - predicate input type
      U - predicate input type
      Parameters:
      components - the BiPredicates to combine
      Returns:
      the composite BiPredicate

    • and

      @SafeVarargs @Nonnull public static <T, U> BiPredicate<T,U> and(@Nonnull BiPredicate<? super T,? super U>... components)
      Returns a BiPredicate that evaluates to true if each of its components evaluates to true. The components are evaluated in order, and evaluation will be "short-circuited" as soon as a false BiPredicate is found. It defensively copies the iterable passed in, so future changes to it won't alter the behavior of this predicate. If components is empty, the returned BiPredicate will always evaluate to true.
      Type Parameters:
      T - predicate input type
      U - predicate input type
      Parameters:
      components - the BiPredicates to combine
      Returns:
      the composite BiPredicate

    • and

      @Nonnull public static <T, U> BiPredicate<T,U> and(@Nonnull BiPredicate<T,U> first, @Nonnull BiPredicate<? super T,? super U> second)
      Returns a BiPredicate that evaluates to true if each of its components evaluates to true. The components are evaluated in order, and evaluation will be "short-circuited" as soon as a false BiPredicate is found. It defensively copies the iterable passed in, so future changes to it won't alter the behavior of this BiPredicate. If components is empty, the returned BiPredicate will always evaluate to true.
      Type Parameters:
      T - predicate input type
      U - predicate input type
      Parameters:
      first - the first BiPredicate
      second - the second BiPredicate
      Returns:
      the composite BiPredicate

    • or

      @Nonnull public static <T, U> BiPredicate<T,U> or(@Nonnull Iterable<? extends BiPredicate<? super T,? super U>> components)
      Returns a BiPredicate that evaluates to true if any one of its components evaluates to true. The components are evaluated in order, and evaluation will be "short-circuited" as soon as a true BiPredicate is found. It defensively copies the iterable passed in, so future changes to it won't alter the behavior of this BiPredicate. If components is empty, the returned BiPredicate will always evaluate to false.
      Type Parameters:
      T - predicate input type
      U - predicate input type
      Parameters:
      components - the BiPredicates to combine
      Returns:
      the composite BiPredicate

    • or

      @SafeVarargs @Nonnull public static <T, U> BiPredicate<T,U> or(@Nonnull BiPredicate<? super T,? super U>... components)

The components are evaluated in order, and evaluation will be "short-circuited" as soon as a true BiPredicate is found. It defensively copies the iterable passed in, so future changes to it won't alter the behavior of this BiPredicate. If components is empty, the returned BiPredicate will always evaluate to false.
      Type Parameters:
      T - predicate input type
      U - predicate input type
      Parameters:
