Summary:
Our JS codegen assumes that all Android view managers extend `BaseViewManager` which allows generated delegates to set base view props using `BaseViewManagerDelegate`, see and example of the generated delegate for `FbReactTTRCStepRenderFlagManager`:
```
public class TTRCStepRenderFlagManagerDelegate<T extends View, U extends BaseViewManager<T, ? extends LayoutShadowNode> & TTRCStepRenderFlagManagerInterface<T>>{
public TTRCStepRenderFlagManagerDelegate(U viewManager) {
super(viewManager);
}
Override
public void setProperty(T view, String propName, Nullable Object value) {
switch (propName) {
case "traceId":
mViewManager.setTraceId(view, value == null ? null : (String) value);
break;
case "stepName":
mViewManager.setStepName(view, value == null ? null : (String) value);
break;
default:
super.setProperty(view, propName, value);
}
}
}
```
The problem is that `FbReactTTRCStepRenderFlagManager` doesn't extend `BaseViewManager`, but `ViewManager`, which means that we cannot use it with the generated delegate. We cannot use `ViewManager` instead of `BaseViewManager` in our JS codegen either, otherwise we will not be able to set base view props.
This diff makes it possible for delegates generated by JS to be used by Android view managers that do not extend `BaseViewManager`. By having a `BaseViewManagerInterface` we will be able to introduce a no-op base view manager implementation and wrap our original view manager in it so that we can pass as a constructor parameter to `BaseViewManagerDelegate`.
See an example of this approach for `FbReactTTRCStepRenderFlagManager`:
```
public class FbReactTTRCStepRenderFlagManager extends ViewManager<FbReactTTRCStepRenderFlag, ReactShadowNodeImpl> implements TTRCStepRenderFlagManagerInterface<FbReactTTRCStepRenderFlag> {
private final ViewManagerDelegate<FbReactTTRCStepRenderFlag> mDelegate;
public FbReactTTRCStepRenderFlagManager() {
mDelegate = new TTRCStepRenderFlagManagerDelegate<>(new ViewManagerWrapper(this));
}
...
private static class ViewManagerWrapper extends BaseViewManagerAdapter<FbReactTTRCStepRenderFlag> implements TTRCStepRenderFlagManagerInterface<FbReactTTRCStepRenderFlag> {
private final TTRCStepRenderFlagManagerInterface<FbReactTTRCStepRenderFlag> mViewManager;
private FbReactTTRCStepRenderFlagManagerAdapter(TTRCStepRenderFlagManagerInterface<FbReactTTRCStepRenderFlag> viewManager) {
mViewManager = viewManager;
}
Override
public void setTraceId(FbReactTTRCStepRenderFlag view, Nullable String traceId) {
mViewManager.setTraceId(view, traceId);
}
Override
public void setStepName(FbReactTTRCStepRenderFlag view, Nullable String stepName) {
mViewManager.setStepName(view, stepName);
}
}
}
```

Summary:
This diff introduces an interface `ViewManagerDelegate` and its base implementation `BaseViewManagerDelegate`, which is used as a parent class for all view manager delegates generated by the JS codegen. Before the changes in this diff, generated delegates didn't support setting the base view properties such as background color, rotation, opacity, etc. Now it's possible to do by using `BaseViewManagerDelegate.setProperty(...)`, and since all generated delegates extend BaseViewManagerDelegate, they can just call `super.setProperty(...)` for properties they don't want to handle.
This diff also introduced a new method `ViewManager.getDelegate()`. This will allow view managers to return an instance of the delegate generated by JS and ensure that the view properties are set in a type-safe manner. If this method returns null (it does by default), we fall back to the default implementation of setting view properties using Java-generated `$$PropsSetter`
classes.
This is an example of an interface class generated by JS:
```
public interface RCTAxialGradientViewViewManagerInterface<T extends View> {
void setColors(T view, Nullable ReadableArray value);
void setLocations(T view, Nullable ReadableArray value);
void setEndX(T view, Float value);
void setEndY(T view, Float value);
void setStartX(T view, Float value);
void setStartY(T view, Float value);
}
```
This is an example of a delegate class generated by JS:
```
public class RCTAxialGradientViewManagerDelegate<T extends View, U extends BaseViewManager<T, ? extends LayoutShadowNode> & RCTAxialGradientViewManagerInterface<T>> extends BaseViewManagerDelegate<T, U> {
public RCTAxialGradientViewManagerDelegate(U viewManager) {
super(viewManager);
}
Override
public void setProperty(T view, String propName, Nullable Object value) {
switch (propName) {
case "colors":
mViewManager.setColors(view, (ReadableArray) value);
break;
case "locations":
mViewManager.setLocations(view, (ReadableArray) value);
break;
case "endX":
mViewManager.setEndX(view, value == null ? Float.NaN : ((Double) value).floatValue());
break;
case "endY":
mViewManager.setEndY(view, value == null ? Float.NaN : ((Double) value).floatValue());
break;
case "startX":
mViewManager.setStartX(view, value == null ? Float.NaN : ((Double) value).floatValue());
break;
case "startY":
mViewManager.setStartY(view, value == null ? Float.NaN : ((Double) value).floatValue());
break;
default:
super.setProperty(view, propName, value);
}
}
}
```
NOTE: What if a view manager, for instance ReactAxialGradientManager, wanted to add support for the borderRadius prop? In the old Java codegen, it would just need to create a method and annotate it with ReactProp (name = ViewProps.BORDER_RADIUS) and $$PropsSetter would call this method when a property with this name must be set. With the new JS codegen, borderRadius is a part of the basic view props, so setBorderRadius is not generated as a part of the ViewManagerInterface, so it’s not possible to set this value. I see two options: 1) add a method boolean setProperty (String propName, Object value) and let the view manager handle it in a non-type safe way (return true if it’s been handled). 2) Generate BaseViewManagerInterface which will include all basic view props and make BaseViewManager implement this interface, leaving all methods empty so that it stays compatible with the current implementation. Override these methods in a view manager that needs to handle a specific property in a custom way (so we would override setBorderRadius in ReactAxialGradientManager).
