oracular / episodeClosed

Function: episodeClosed()

function episodeClosed(prev, next): boolean;

Defined in: observe.ts:156

Whether an episode closed between two states: prev had an open episode and next either has none or has a different one. Useful after observe or endEpisode to react to a session ending, for example to persist, or to read the misses it produced as next.intents[x].episodes.misses - prev.intents[x].episodes.misses (0 for an intent with attribution set, whose verdict waits).

Parameters

Parameter	Type	Description
prev	EngineState	The state before the operation.
next	EngineState	The state after it.

Returns

boolean

True when prev.episode.startedAt is not null and differs from next.episode.startedAt.

Throws

TypeError when either argument is not an engine state.

Example

const next = observe(state, event);
if (episodeClosed(state, next)) persist(next);
