Class NativeAdapterComponent<I extends Component>

java.lang.Object

react4j.NativeComponent

react4j.NativeAdapterComponent<I>

Type Parameters:

I - the type of the native component.

public abstract class NativeAdapterComponent<I extends Component>
extends NativeComponent

This class provides a base class that designed to forward all lifecycle methods to a target component. The target component is of type Component. This class is also responsible for calling Component.setLifecycleMethod(LifecycleMethod) before and after each call to the target component if ReactConfig.checkComponentStateInvariants() returns true. This will make it possible for the target component to check that the application code is correctly interacting with the React component framework. In production builds it is expected that the method calls will be inlined and the checks will be optimized away, having no significant performance impact.

@JsConstructor
protected NativeAdapterComponent(@Nullable
                                                jsinterop.base.JsPropertyMap<java.lang.Object> props)

Create a component that designed to delegate to a target component.

Parameters:

props - the initial props.

Method Detail

createComponent

protected abstract I createComponent()

Template method that actually creates the target component.

Returns:

a new instance of the target component.

render

@Nullable
public final ReactNode render()

Call render on the target component.

Specified by:

render in class NativeComponent

Returns:

the output of rendering.
