ReadWriteProperty

interface ReadWriteProperty<in R, T> (source)

Base interface that can be used for implementing property delegates of read-write properties.

This is provided only for convenience; you don't have to extend this interface as long as your property delegate has methods with the same signatures.

Parameters

R - the type of object which owns the delegated property.

T - the type of the property value.

Functions

getValue

abstract operator fun getValue(
    thisRef: R,
    property: KProperty<*>
): T

Returns the value of the property for the given object.

setValue

abstract operator fun setValue(
    thisRef: R,
    property: KProperty<*>,
    value: T)

Sets the value of the property for the given object.

Inherited Functions

equals

open operator fun equals(other: Any?): Boolean

Indicates whether some other object is "equal to" this one. Implementations must fulfil the following requirements:

hashCode

open fun hashCode(): Int

Returns a hash code value for the object. The general contract of hashCode is:

toString

open fun toString(): String

Returns a string representation of the object.

Inheritors

ObservableProperty

abstract class ObservableProperty<T> : 
    ReadWriteProperty<Any?, T>

Implements the core logic of a property delegate for a read/write property that calls callback functions when changed.
