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.
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>If set, this.context will be set at runtime to the current value of the given Context.
Usage:
type MyContext = number
const Ctx = React.createContext<MyContext>(0)
class Foo extends React.Component {
static contextType = Ctx
context!: React.ContextType<typeof Ctx>
render () {
return <>My context's value: {this.context}</>;
}
}Called immediately before mounting occurs, and before Component#render.
Avoid introducing any side-effects or subscriptions in this method.
This method will not stop working in React 17.
Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps prevents this from being invoked.
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.
This method will not stop working in React 17.
Note: the presence of getSnapshotBeforeUpdate or getDerivedStateFromProps prevents this from being invoked.
Called immediately before rendering when new props or state is received. Not called for the initial render.
Note: You cannot call Component#setState here.

Given a chart data entry, sets node options if one is already set for this point.
A single chart data entry.
Catches exceptions generated in descendant components. Unhandled exceptions will cause the entire component tree to unmount.
Called immediately before mounting occurs, and before Component#render.

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

Returns an {i, j} pair for a hovered residue. Handles case when a single residue is hovered.
Array of residues that are hovered.
Returns contact map points for locked residue pairs.
Gets the color from the provided chart entry.
The following are checked in order - the first one found is the color returned:
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 getSnapshotBeforeUpdate prevents any of the deprecated lifecycle events from running.
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.
