LambdaSlot

java.lang.Object
- org.htmlunit.corejs.javascript.Slot
- - org.htmlunit.corejs.javascript.LambdaSlot

All Implemented Interfaces:

java.io.Serializable
```
public class LambdaSlot
extends Slot
```
This is a specialization of property access using some lambda functions. It behaves exactly like any other slot that has only a value, but instead of getting the value directly, it comes from calling the functions. This makes it different from GetterSlot, which lets the user see directly that there is a getter or a setter function involved. This makes this class useful for implementing properties that behave like any other JavaScript property but which are implemented using some native functionality without using reflection.
