getValue
An extension operator that allows delegating a read-only property of type V to a property reference to a property of type V or its subtype.
Since Kotlin
1.4Receiver
A property reference to a read-only or mutable property of type V or its subtype. The reference is without a receiver, i.e. it either references a top-level property or has the receiver bound to it.
Example:
class Login(val username: String)
val defaultLogin = Login("Admin")
val defaultUsername by defaultLogin::username
// equivalent to
val defaultUserName get() = defaultLogin.username
An extension operator that allows delegating a read-only member or extension property of type V to a property reference to a member or extension property of type V or its subtype.
Since Kotlin
1.4Receiver
A property reference to a read-only or mutable property of type V or its subtype. The reference has an unbound receiver of type T.
Example:
class Login(val username: String)
val Login.user by Login::username
// equivalent to
val Login.user get() = this.username
An extension to delegate a read-only property of type T to an instance of Lazy.
This extension allows to use instances of Lazy for property delegation: val property: String by lazy { initializer }
