Question

the idea is there though < karelpeeters>

karelpeeters · Answer

If a filter isn t active shouldn t it return `true`

oday · Answer

what I mean is that it should skip over it true would mean that it did match that criteria

oday · Answer

oh

karelpeeters · Answer

Right

karelpeeters · Answer

I m also confused as to why you need two arrays one with strings and one with predicated based on them Just handle the disabled ness in the call to `all`

karelpeeters · Answer

And then why the `ArrayList` at the end

oday · Answer

there s no position in `all`

oday · Answer

and arraylist because the method im calling takes an arraylist not necessary

karelpeeters · Answer

Then you should use `filterTo ArrayList ` But what a weird method

oday · Answer

nah I can have it handle a list of course

oday · Answer

just havent yet

karelpeeters · Answer

Why do need the position in `all`

oday · Answer

to be able to check if currentFilter is active

oday · Answer

if currentFilters 0 active

oday · Answer

need to know which one im referring to

karelpeeters · Answer

I d do `originalListings filter listing gt currentFilters all str enabled gt enabled || listing tags = null amp amp listing tags isNotEmpty amp amp listing tags 0 = getString str `

karelpeeters · Answer

And drop the `predicates` list

oday · Answer

inside each of the predicates

oday · Answer

yea

oday · Answer

what that only handles 1 case

oday · Answer

there are 5 filters

karelpeeters · Answer

Ah I only looked at the first two and assumed everything else was the same pattern

oday · Answer

so predicate list is needed

karelpeeters · Answer

Yeah but the handing of being enabled should not be manually handles when creating the list like this

oday · Answer

yea i can pass a position and do it when needed

karelpeeters · Answer

Then I d so somehting like this ``` class Filter val str String val pred CarLeasingResponse gt Boolean var enabled Boolean val filters = listOf Filter Filter originalListings filter listing gt filters all it enabled || it pred listing ```

oday · Answer

I actually went and created a MutableTriple laughing

oday · Answer

when I tried this before

oday · Answer

yea class would do

karelpeeters · Answer

Pairs and triples are kind of shady it s better to just make a class it s so short in Kotlin

oday · Answer

that is beautiful actually

oday · Answer

i think the misunderstanding of returning True in filter was my issue I thought the inverse

oday · Answer

and the overly complicated design slightly smiling face

oday · Answer

I seem to be at a loss here I m unable to express the idea of matches this active filter or that active filter or that active filter together right now i match each 1 by itself

oday · Answer

like if I have cars that have property X and property Y and property F if I say filter X and filter Y are ON i want to see cars matching both these predicates

oday · Answer

i think i should get rid of the `all` on currentFilters and just place the predicates in a long if statement with ORs for each predicate

arve · Answer

you just said two opposite statements thinking face ` matches this active filter or that active filter or that active filter ` vs `filter X and filter Y are ON i want to see cars matching both these predicates` Are you sure you don t mean `filter X and filter Y are ON i want to see cars matching at least one of these predicates` If that s the case you might be looking for `Collections any predicate ` as opposed to `all`

oday · Answer

I knew it

oday · Answer

i knew i could use any

oday · Answer

HA

oday · Answer

thanks

oday · Answer

i came here to say that i think any would work smile

karelpeeters · Answer

Are you sure you need `any` An if with a bunch of conditions with ` amp amp ` gt `all` and `||` gt `any`

oday · Answer

any isnt doing anything anyways i have no idea why it s clear that i want to return true whenever an item in the current filters is active and its predicate returns true

oday · Answer

ill debug it actually but with if s i dont know if you can achieve this cleanly

karelpeeters · Answer

You require all active filters to match right

karelpeeters · Answer

That s what my example code earlier did

karelpeeters · Answer

`filters all it enabled || it pred listing `

oday · Answer

that s how it was

oday · Answer

that only does 1 type of filter at a time

oday · Answer

if a certain objects content match 2 of the filters i want to include those as well

oday · Answer

then im doing something wrong

oday · Answer

when im running it i can never reach a number higher than what i first started with

oday · Answer

if I filter for something and get 30 results it can never grow only shrinks

oday · Answer

its not adding them or im displaying them immediately or something

oday · Answer

yea there s something about the problem im not undersatnding thanks for the help so far really

oday · Answer

for example if I have all filters on all the list should be shown

karelpeeters · Answer

That doesn t make sense a filter removes stuff

oday · Answer

exactly my thoughts in the beginning this is then called something else

oday · Answer

i argued when I heard about it but I am checking how it s done in another platform same software as im making that s how it behaves

karelpeeters · Answer

Call them matchers then or something

oday · Answer

that s what i thought from the begining it s fucking insane what they re describing the more filters you have the closer you are to the original list

oday · Answer

they were wrong I am not insane slightly smiling face

oday · Answer

turns out indeed that it was just matching a very weird way of matching totally insane all just for the issue of not having to show an empty result when 2 of the criteria conflict instead of fixing what the criteria is
