Interface ISerializableThrowingFunction<T,​R>

  • Type Parameters:
    T - the type of the input to the function
    R - the type of the result of the function
    All Superinterfaces:
    Function<T,​R>, Serializable
    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 ISerializableThrowingFunction<T,​R>
extends Function<T,​R>, Serializable
    A Supplier that is also serializable and can throw exceptions.

    Represents a function that accepts one argument and produces a result.

    This is a functional interface whose functional method is apply(Object).

    • Method Detail

      • tryApply

        R tryApply​(T t)
    throws Exception
        Gets a result.
        Parameters:
        t - the function argument
        Returns:
        the function result
        Throws:
        Exception - When this operation fails.

      • apply

        default R apply​(T t)
        Specified by:
        apply in interface Function<T,​R>

      • of

        static <T,​R> ISerializableThrowingFunction<T,​R> of​(ISerializableThrowingFunction<T,​R> supplier)
        Returns the given supplier, for improved variable inference. Sometimes you need to create local variables and assign them to a new lambda. This does not work well with variable inference, as Java cannot infer the type of an anonymous lambda. This utility method lets you write slightly more readable code like this: 
         final var fn = ISerializableThrowingFunction.of(t -> ...);

 
        

        

        Type Parameters:
        

        T - the type of results supplied by this supplier
        

        Parameters:
        

        supplier - Supplier to return.
        

        Returns:
        

        The given supplier.
