interface ReadWriteProperty<in R, T>
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.
R - the type of object which owns the delegated property.
T - the type of the property value.
abstract operator fun getValue( thisRef: R, property: KProperty<*> ): T Returns the value of the property for the given object. | |
abstract operator fun setValue( thisRef: R, property: KProperty<*>, value: T) Sets the value of the property for the given object. |
open operator fun equals(other: Any?): Boolean Indicates whether some other object is "equal to" this one. Implementations must fulfil the following requirements: | |
open fun hashCode(): Int Returns a hash code value for the object. The general contract of hashCode is: | |
open fun toString(): String Returns a string representation of the object. |
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. |
