Optimizing Access to Properties

Properties are class members that hold values and define rules for reading and writing those values. In Kotlin, the properties of a class represent the current state of an instance of that class. A typical class with properties looks like this:

class Button {

var text: String = TODO()

var backgroundColor: Int = TODO()

var onClickListener: ((Button) -> Unit)? = null

}

We can use this class to create objects and set values for the text, backgroundColor, and onClickListener properties. A combination of these properties in one object represents the state of an instance of the Button class.

In this chapter, we'll cover the following topics:

  • Fields and properties

  • Code inspection
