Constructors​

new ViewAdapter()​

new ViewAdapter(props): ViewAdapter

Defined in: packages/react-page-renderer/src/component/ViewAdapter.ts:42

Initializes the adapter component.

Parameters​

props​

ViewAdapterProps

Component properties, containing the actual page view and the initial page state to pass to the view.

Properties​

context​

context: unknown

Defined in: node_modules/@types/react/index.d.ts:1013

If using the new style context, re-declare this in your class to be the React.ContextType of your static contextType. Should be used with type annotation or static contextType.

Example​

static contextType = MyContext
// For TS pre-3.7:
context!: React.ContextType<typeof MyContext>
// For TS 3.7 and above:
declare context: React.ContextType<typeof MyContext>

Methods​

componentDidCatch()?​

optional componentDidCatch(error, errorInfo): void

Defined in: node_modules/@types/react/index.d.ts:1397

Catches exceptions generated in descendant components. Unhandled exceptions will cause the entire component tree to unmount.

Parameters​

error​

Error

errorInfo​

ErrorInfo

Returns​

void

Inherited from​

Component.componentDidCatch

componentDidMount()?​

optional componentDidMount(): void

Defined in: node_modules/@types/react/index.d.ts:1376

Called immediately after a component is mounted. Setting state here will trigger re-rendering.

Returns​

void

Inherited from​

Component.componentDidMount

componentDidUpdate()?​

optional componentDidUpdate(prevProps, prevState, snapshot?): void

Defined in: node_modules/@types/react/index.d.ts:1439

Called immediately after updating occurs. Not called for the initial render.

The snapshot is only present if getSnapshotBeforeUpdate is present and returns non-null.

Parameters​

prevProps​

Readonly<ViewAdapterProps>

prevState​

Readonly<State>

snapshot?​

any

Returns​

void

Inherited from​

Component.componentDidUpdate

componentWillMount()?​

optional componentWillMount(): void

Defined in: node_modules/@types/react/index.d.ts:1455

Called immediately before mounting occurs, and before Component.render. Avoid introducing any side-effects or subscriptions in this method.

Note: the presence of getSnapshotBeforeUpdate or StaticLifecycle.getDerivedStateFromProps getDerivedStateFromProps prevents this from being invoked.

Returns​

void

Deprecated​

16.3, use componentDidMount or the constructor instead; will stop working in React 17

See​

Inherited from​

Component.componentWillMount

componentWillReceiveProps()?​

optional componentWillReceiveProps(nextProps, nextContext): void

Defined in: node_modules/@types/react/index.d.ts:1486

Called when the component may be receiving new props. React may call this even if props have not changed, so be sure to compare new and existing props if you only want to handle changes.

Calling Component.setState generally does not trigger this method.

Note: the presence of getSnapshotBeforeUpdate or StaticLifecycle.getDerivedStateFromProps getDerivedStateFromProps prevents this from being invoked.

Parameters​

nextProps​

Readonly<ViewAdapterProps>

nextContext​

any

Returns​

void

Deprecated​

16.3, use static StaticLifecycle.getDerivedStateFromProps getDerivedStateFromProps instead; will stop working in React 17

Component.componentWillReceiveProps

componentWillUnmount()?​

optional componentWillUnmount(): void

Defined in: node_modules/@types/react/index.d.ts:1392

Called immediately before a component is destroyed. Perform any necessary cleanup in this method, such as cancelled network requests, or cleaning up any DOM elements created in componentDidMount.

Returns​

void

Inherited from​

Component.componentWillUnmount

componentWillUpdate()?​

optional componentWillUpdate(nextProps, nextState, nextContext): void

Defined in: node_modules/@types/react/index.d.ts:1518

Called immediately before rendering when new props or state is received. Not called for the initial render.

Note: You cannot call Component.setState here.

Note: the presence of getSnapshotBeforeUpdate or StaticLifecycle.getDerivedStateFromProps getDerivedStateFromProps prevents this from being invoked.

Parameters​

nextProps​

Readonly<ViewAdapterProps>

nextState​

Readonly<State>

nextContext​

any

Returns​

void

Deprecated​

Returns​

PageContextType

getSnapshotBeforeUpdate()?​

optional getSnapshotBeforeUpdate(prevProps, prevState): any

Defined in: node_modules/@types/react/index.d.ts:1433

Runs before React applies the result of render to the document, and returns an object to be given to componentDidUpdate. Useful for saving things such as scroll position before render causes changes to it.

Note: the presence of this method prevents any of the deprecated lifecycle events from running.

Parameters​

prevProps​

Readonly<ViewAdapterProps>

prevState​

Readonly<State>

Returns​

any

shouldComponentUpdate()?​

optional shouldComponentUpdate(nextProps, nextState, nextContext): boolean

Defined in: node_modules/@types/react/index.d.ts:1387

Called to determine whether the change in props and state should trigger a re-render.

Component always returns true. PureComponent implements a shallow comparison on props and state and returns true if any props or states have changed.

If false is returned, Component.render, componentWillUpdate and componentDidUpdate will not be called.

Parameters​

nextProps​

Readonly<ViewAdapterProps>

nextState​

Readonly<State>

nextContext​

any

Returns​

boolean
