Revision retrieval handler​

This example demonstrates how the

onRevisionGet
callback retrieves a revision from an in-memory collection maintained by the host application using the provided revision key. Once the lookup is complete, the result is returned to the widget through the

onResponse
callback.
TypeScript
Revision retrieval handler
onRevisionGet: (revisionKey: string, onResponse: (result: DIQ_Result, revision: DIQ_Revision | null) => void) => {
    const revision = revisionStore.find(r => r.key === revisionKey);

    if (revision) {
        onResponse({ success: true }, revision);
    } else {
        onResponse({ success: false, error: "Revision not found" }, null);
    }
}
