Property - Initialize a map property only once

Support
1

I have a map as my property.
Key - String, Value - Complex object
The map will be initialized during runtime using contents from a json file.

I want to read the json file only once at the beginning and initialize the map.
I will then add/ update the map. During every update to the map, I will write to the json file.
I want to make sure that I get the updated map every single time I use it.

Kindly suggest if Kotlin’s backing properties will be useful for my use case.
If not, kindly suggest an approach that I can follow.

I mean, do you know the shape of your JSON or is that also determined at runtime? That makes a difference

The shape of the json is predetermined and will remain the same.
It will look something like this.

{
    "mapKey1": {
        "complexObjectVarA": "...",
        "complexObjectVarB": "..."
    },
    "mapKey2": {
        "complexObjectVarA": "...",
        "complexObjectVarB": "..."
    }
}

I am able to parse this json to the map.
I am looking at ways on how this map can be initialized only once for the kotlin class’s instance and then be reused (instead of parsing the json again).

In that case, I think a property delegate that you initialize with the read value and that then writes on setValue operations (or queues the write, depending on your setup) should work for you

It worked. Thanks!
