Passing parameters to a custom getter in kotlin

Question

I have been reading about properties in Kotlin, including custom getters and setters.

However, I was wondering if it is possible to create a custom getter with extra parameters.

For example, consider the following method in Java:

public String getDisplayedValue(Context context) {
    if (PrefUtils.useImperialUnits(context)) {
        // return stuff
    } else {
        // return other stuff
    }
}

Note that the static method in PrefUtils has to have Context as a parameter, so removing this is not an option.

I would like to write it like this in Kotlin:

val displayedValue: String
    get(context: Context) {
        return if (PrefUtils.useImperialUnits(context)) {
            // stuff
        } else {
            // other stuff
        }
    }

But my IDE highlights all of this in red.

I am aware I can create a function in my class to get the displayed value, but this would mean I would have to use .getDisplayedValue(Context) in Kotlin as well instead of being able to refer to the property by name as in .displayedValue.

Is there a way to create a custom getter like this?

EDIT: If not, would it be best to write a function for this, or to pass Context into the parameters of the class constructor?

Answer 1

As far as I know, property getter cannot have parameter. Write a function instead.
