24 * This service generates swagger (See
25 * <a href="https://helloreverb.com/developers/swagger"
26 * >https://helloreverb.com/developers/swagger</a>) compliant documentation for
27 * RESTCONF APIs. The output of this is used by embedded Swagger UI.
30 * NOTE: These API's need to be synchronized due to bug 1198. Thread access to
31 * the SchemaContext is not synchronized properly and thus you can end up with
32 * missing definitions without this synchronization. There are likely otherways
33 * to work around this limitation, but given that this API is a dev only tool
34 * and not dependent UI, this was the fastest work around.
