How to feed one data class with another?

Asked 2021-May-25 at 18:50

I'm trying to construct a simple application to make operations like comparing, adding objects to Hall of Fame list, etc. I'm pretty sure the Owner class is built correctly, but when feeding the HallOfFame objects with Owner objects, I get many errors.

The app looks like this so far:

The second class doesn't look like it should be dataclass

You can just make normal class
and it's __init__ and other methods that you need (__str__, __eq__, ...)

dataclasses are made to be for storing data
like structs in other languages
with built-in functionality (hash, equality, ...)

I also wrongly commented that __init__ would be overwritten
It wouldn't, but it is recommended to use __post_init__ instead
because dataclass will make a convenient constructor

You can't create attributes after you have started creating child nodes. So, if you are transforming the @id into then you have to do that AFTER you have copied the other attributes.

The shortest and easiest way to avoid the problem is to sort the attributes, ensuring that the ones that will be copied forward are processed first, then the ones that will be converted to elements.

You could achieve that by sorting the sequence of items returned from the hof:remove-attr-except() function, ensuring that the sequence has attributes and then the elements:

How do I extract the generics of a function?

There is some support for higher order type inference from generic functions, but it is heuristic in nature and it only happens in certain circumstances. Instead of having a single type parameter F corresponding to the whole function, you'll have a better time with two type parameters corresponding to the argument list A and the return type R:

All looks correct except; probably you are incorrectly importing compose function.

It is a default export, not a named one. So, the correct way to import is:

QUESTION

Using scala.Option functionally

Asked 2021-Mar-28 at 19:15

I have an Option, say O, which can either be None or may have some value inside. If it has some value, that value may have a flag, say f. My requirement is that if O is None, then I create an object, say of type MyEntity,but if O has a value with flag as true, I return Nil else I create instance of MyEntity with different value. Java code can be almost as:

ANSWER

Answered 2021-Mar-24 at 17:57

As mentioned in the comments, Nil type is a List, and your expression should always return the same type (should really not be Any).

One possibility is to define a "sentinel" value for MyEntity, e.g.:

QUESTION

Is there a shorter way of solving this using higher order functions? Perhaps the filter method?

Asked 2021-Mar-20 at 09:45

Return a new array without the most expensive thing in the list. Your function should preserve the order of the items in this array. The code is correct and so is the output. I don't have a lot of exp with HOF so I would like to see how this can be done using the filter method.

...

ANSWER

Answered 2021-Mar-20 at 05:26

You can find the most expensive item by mapping the array to the prices and calling Math.max on it. Then filter the array by whether the current item being iterated over has that price:

Support

Both MSVC and gcc 4.6 have limited constexpr support due to many bugs in the implementation of constexpr. However, constexpr initialization of functions is supported when using the [BOOST_HOF_STATIC_FUNCTION](BOOST_HOF_STATIC_FUNCTION) and [BOOST_HOF_STATIC_LAMBDA_FUNCTION](BOOST_HOF_STATIC_LAMBDA_FUNCTION) constructs.
