Interface UncheckedFunction<T,R>

Type Parameters:
T - the type of the input to the function
R - the type of the result of the function
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface public interface UncheckedFunction<T,R>
Represents a function that accepts one argument and produces a result.

The operation can throw Exceptions.

  • Method Details

    • from

      static <T, R> UncheckedFunction<T,R> from(Function<T,R> function)
      Creates a UncheckedBiConsumer from an existing Function
      Type Parameters:
      T - the type of the input to the function
      R - the type of the result of the function
      Parameters:
      function - the function
      Returns:
      the created UncheckedBiConsumer
    • apply

      R apply(T t) throws Exception
      Applies this function to the given argument.
      Parameters:
      t - the function argument
      Returns:
      the function result
      Throws:
      Exception - if anything wrong happen
    • toFunction

      default Function<T,R> toFunction()
      Returns:
      a Function executing this UncheckedFunction. If the operation throws an exception, the exception is rethrown, wrapped in a RuntimeException if needed.
    • compose

      default <V> UncheckedFunction<V,R> compose(UncheckedFunction<? super V,? extends T> before)
      Returns a composed function that first applies the before function to its input, and then applies this function to the result. If evaluation of either function throws an exception, it is relayed to the caller of the composed function.
      Type Parameters:
      V - the type of input to the before function, and to the composed function
      Parameters:
      before - the function to apply before this function is applied
      Returns:
      a composed function that first applies the before function and then applies this function
      Throws:
      NullPointerException - if before is null

    • andThen

      default <V> UncheckedFunction<T,V> andThen(UncheckedFunction<? super R,? extends V> after)
      Returns a composed function that first applies this function to its input, and then applies the after function to the result. If evaluation of either function throws an exception, it is relayed to the caller of the composed function.
      Type Parameters:
      V - the type of output of the after function, and of the composed function
      Parameters:
      after - the function to apply after this function is applied
      Returns:
      a composed function that first applies this function and then applies the after function
      Throws:
      NullPointerException - if after is null
