Can I turn this into a property with a `private set` and cus kotlinlang #getting-started

java
  private ProjctSdksModel myModel
  public ProjectSdksModel getModel() {
    if (myModel == null) {
      myModel = new ProjectSdksModel();
      myModel.reset(null);
    }
    return myModel;

If I try

kotlin
var model: ProjectSdksModel? = null
        get() {
            if (this.model == null) {

            }

            return this.model
        }
        private set

I get warning that

this.model

is or

model

is recursive and my google-fu is failing for how to refer to the current property inside the getter

Inside your getter, you need to replace

this.model

with

field

Thanks @Ruckus

Is there something I should be doing different to avoid having to do

!!

immediately after initializing the

field

? I assume the mutability warning is for concurrency

get() {
            if (field == null) {
                field = ProjectSdksModel()
                field!!.reset(null)
            }

            return field
        }

Maybe I should go the "Backing Properties" route, because the getter is non-null even if the field is null

You could always use something like

field = ProjectSdksModel().apply { reset(null) }

But in this case, backing properties are the way to go.

Is there a more compact way to handle the

null

reset back to

field

. It's not just a lateinit - there's other code that can reset the field to

null

I don't know what

reset(null)

does, but a backing property should help separate the logic more cleanly.

You can use lateinit backing property
