How to do it...

Let's see how to work with inline properties in these steps:

1. Let's try an example where we inline an accessor of a property in Kotlin:

var x.valueIsMaxedOut: Booleaninline get() = x.value == CONST_MAX

2. In this example, we just used the inline keyword with the get accessor. We can also declare both the get and set accessors as inline by making the whole property inline, as shown in this code snippet:

inline var x.valueIsMaxedOut: Booleanget() = x.value == CONST_MAXset(value) {    // set field here    println(“Value set!”)}

In the preceding snippet, both accessors are inlined.

3. One thing to keep in mind, though, is that inline does not work with property or accessor if the property has a backing field or the assessor does not reference ...
