Class LambdaAccessorSlot

java.lang.Object

org.htmlunit.corejs.javascript.Slot

org.htmlunit.corejs.javascript.LambdaAccessorSlot

All Implemented Interfaces:

Serializable

public class LambdaAccessorSlot
extends Slot

A specialized property accessor using lambda functions, similar to LambdaSlot, but allows defining properties with getter and setter lambdas that require access to the owner object ('this'). This enables the implementation of properties that can access instance fields of the owner.

Unlike LambdaSlot, Lambda functions used to define getter and setter logic require the owner's `Scriptable` object as one of the parameters. This is particularly useful for implementing properties that behave like standard JavaScript properties, but are implemented with native functionality without the need for reflection.

Method Detail

buildPropertyDescriptor

public ScriptableObject buildPropertyDescriptor(Context cx)

The method exists avoid changing the getPropertyDescriptor signature and at the same time to make it explicit that we don't use Scriptable scope parameter of getPropertyDescriptor, since it can be problematic when called from inside ThreadSafeSlotMapContainer::compute lambda which can lead to deadlocks.

                        boolean isThrow)

Overrides:

setValue in class Slot

getValue
