LayoutStateContext

java.lang.Object
- com.facebook.litho.LayoutStateContext

All Implemented Interfaces:

CalculationStateContext
```
public class LayoutStateContext
extends java.lang.Object
implements CalculationStateContext
```
Wraps objects which should only be available for the duration of a LayoutState, to access them in other classes such as ComponentContext during layout state calculation. When the layout calculation finishes, the LayoutState reference is nullified. Using a wrapper instead of passing the instances directly helps with clearing out the reference from all objects that hold on to it, without having to keep track of all these objects to clear out the references.
