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.

Called immediately before rendering when new props or state is received. Not called for the initial render.
Note: You cannot call Component#setState
here.

Catches exceptions generated in descendant components. Unhandled exceptions will cause the entire component tree to unmount.
Invoked after the component is first mounted. Launches an API request to retrieve the list of existing documents from the server and update the state.
Called immediately after updating occurs. Not called for the initial render.
The snapshot is only present if getSnapshotBeforeUpdate is present and returns non-null.

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
.

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.
Callback invoked in response to the user updating the selected upload method. Stores the new value to local storage and updates the state.
The original change event
Renders the component
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.
Callback invoked in response to the user submitting the form. This function checks the selected input method and formats the data, chooses the request endpoint accordingly and submits the data to the server. If the request completes successfully, a new session using the newly created document ID is initialised.
The original form event
Generated using TypeDoc
DocumentChooser enables the user to start a new session by loading a new document. This can be done in threee different ways:
In the first two cases, upon submit, the component sends the data to the server and receives a new document ID. With this, the
assignDocumentId
callback is invoked to let the parent know that a document has been selected. In the third case, the document does not need to be allocated on the server, since it already exists. In that case,assignDocumentId
is invoked immediately.Callback invoked when a document ID has been selected
Callback invoked when the user updates the trigger mode
