`@AuraEnabled` Annotations for Continuations

Continuations use the @AuraEnabled annotation for Apex code. Here are the rules for usage.

@AuraEnabled(continuation=true)

An Apex controller method that returns a continuation must be annotated with @AuraEnabled(continuation=true).
@AuraEnabled(continuation=true cacheable=true)

To cache the result of a continuation action, set cacheable=true on the annotation for the Apex callback method.

There’s a space, not a comma, between continuation=true cacheable=true.

It's best practice to set cacheable=true on all methods involved in the continuation chain, including the method that returns a Continuation object.

In this example, the Apex method that returns the continuation, startRequest(), and the callback, processResponse(), both contain cacheable=true in their @AuraEnabled annotation.

Here's a table that summarizes the behavior with different settings of the cacheable attribute in @AuraEnabled.

Method Returning Continuation Object Annotated with `cacheable=true`	Callback Method Annotated with `cacheable=true`	Valid?	Can be Called Using `@wire`?	Is Action Response Cached on Client?
Yes	Yes	Yes	Yes	Yes
Yes	No	No (throws an exception)	N/A	N/A
No	Yes	Yes	No (all methods must have `cacheable=true`)	No
No	No	Yes	No	No
