Classes

Class	Alerts	Description
EpochTracker	Legacy	In ODSP, the concept of "epoch" refers to binary updates to files. For example, this might include using version restore, or if the user downloads a Fluid file and then uploads it again. These result in the epoch value being incremented. The implications of these binary updates is that the Fluid state is disrupted: the sequence number might go backwards, the data might be inconsistent with the latest state of collaboration, etc. As a result, it's not safe to continue collaboration across an epoch change. We need to detect these epoch changes and error out from the collaboration. This class is a wrapper around fetch calls. It adds epoch to the request made so that the server can match it with its epoch value in order to match the version. It also validates the epoch value received in response of fetch calls. If the epoch does not match, then it also clears all the cached entries for the given container.
OdspDocumentServiceFactory	Legacy	Factory for creating the sharepoint document service. Use this if you want to use the sharepoint implementation.
OdspDocumentServiceFactoryCore	Legacy	Factory for creating the sharepoint document service. Use this if you want to use the sharepoint implementation. This constructor should be used by environments that support dynamic imports and that wish to leverage code splitting as a means to keep bundles as small as possible.
OdspDriverUrlResolver	Legacy	Resolver to resolve urls like the ones created by createOdspUrl which is driver inner url format. Ex: ${siteUrl}?driveId=${driveId}&itemId=${itemId}&path=${path}
OdspDriverUrlResolverForShareLink	Legacy	Resolver to resolve urls like the ones created by createOdspUrl which is driver inner url format and the ones which have things like driveId, siteId, itemId etc encoded in nav param. This resolver also handles share links and try to generate one for the use by the app.

checkUrl(documentUrl)	Legacy	DriverPreCheckInfo | undefined	A check that returns DriverPreCheckInfo if the URL format is likely supported by this driver. Note that returning information here is NOT a full guarantee that resolve will ultimately be successful. Instead, this should be used as a lightweight check that can filter out easily detectable unsupported URLs before the entire Fluid loading process needs to be kicked off.

getLocatorFromOdspUrl(url, requireFluidSignature)	Legacy	OdspFluidDataStoreLocator | undefined	Extract ODSP Fluid data store locator object from given ODSP url. This extracts things like driveId, ItemId, siteUrl etc from a url where these are encoded in nav query param.
