`PersisterListener`

A PersisterListener is a callback that lets a Persister inform the Store that a change has happened to the underlying data.

(
  getContent?: () => [Tables, Values],
  getTransactionChanges?: GetTransactionChanges,
): void

	Type	Description
`getContent?`	`() => [Tables, Values]`	An optional function that, if provided, returns an array of `Store` content and can be used to immediately wholesale update the `Store`.
`getTransactionChanges?`	`GetTransactionChanges`	An optional function that, if provided, returns a `TransactionChanges` object and can be used to immediately incrementally update the `Store`.
returns	`void`	This has no return value.

If the listener has the getTransactionChanges parameter, it will be used to make an incremental change to the Store. If not, but the getContent function is available, that will be used to make a wholesale change to the Store. If neither are present, the content will be loaded from the Persister's load method.
