Static Optional componentDidCatch

componentDidCatch(error: Error, errorInfo: ErrorInfo): void

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

Parameters
- error: Error
- errorInfo: ErrorInfo
Returns void

Static Optional componentDidMount

componentDidMount(): void

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

Returns void

Static Optional componentDidUpdate

componentDidUpdate(prevProps: Readonly<IMapViewerBaseProps>, prevState: Readonly<Partial<IMapViewerBaseState>>, prevContext: any): void

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

Parameters
- prevProps: Readonly<IMapViewerBaseProps>
- prevState: Readonly<Partial<IMapViewerBaseState>>
- prevContext: any
Returns void

Static Optional componentWillMount

componentWillMount(): void

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

Returns void

Static Optional componentWillReceiveProps

componentWillReceiveProps(nextProps: Readonly<IMapViewerBaseProps>, nextContext: any): void

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.

Parameters
- nextProps: Readonly<IMapViewerBaseProps>
- nextContext: any
Returns void

Static Optional componentWillUnmount

componentWillUnmount(): void

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

Static Optional componentWillUpdate

componentWillUpdate(nextProps: Readonly<IMapViewerBaseProps>, nextState: Readonly<Partial<IMapViewerBaseState>>, nextContext: any): void

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

Note: You cannot call Component#setState here.

Parameters
- nextProps: Readonly<IMapViewerBaseProps>
- nextState: Readonly<Partial<IMapViewerBaseState>>
- nextContext: any
Returns void

Static Optional shouldComponentUpdate

shouldComponentUpdate(nextProps: Readonly<IMapViewerBaseProps>, nextState: Readonly<Partial<IMapViewerBaseState>>, nextContext: any): boolean

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<IMapViewerBaseProps>
- nextState: Readonly<Partial<IMapViewerBaseState>>
- nextContext: any
Returns boolean
