  • Method Details

    • to

      <T> Function<Object,T> to(Class<T> cls)
      Specify the target object type for the conversion as a class object.
      Type Parameters:
      T - The type to convert to.
      Parameters:
      cls - The class to convert to.
      Returns:
      A function that can perform the conversion.

    • to

      <T> Function<Object,T> to(Type type)
      Specify the target object type as a Java Reflection Type object.
      Type Parameters:
      T - The type to convert to.
      Parameters:
      type - A Type object to represent the target type to be converted to.
      Returns:
      A function that can perform the conversion.

    • to

      <T> Function<Object,T> to(TypeReference<T> ref)
      Specify the target object type as a TypeReference. If the target class carries generics information a TypeReference should be used as this preserves the generic information whereas a Class object has this information erased. Example use: 
       List<String> result = converter.function()
                .to(new TypeReference<List<String>>() {
                });
      Type Parameters:
      T - The type to convert to.
      Parameters:
      ref - A type reference to the object being converted to.
      Returns:
      A function that can perform the conversion.
