Interface BatchUpdateBlobProvider

All Known Implementing Classes:

AbstractLiveConnectBlobProvider, BoxBlobProvider, GoogleDriveBlobProvider

public interface BatchUpdateBlobProvider

Interface to batch update documents provided by implementing provider. The method processDocumentsUpdate() is called by BlobProviderDocumentsUpdateListener.

The implementation of processDocumentsUpdate() must schedule a BlobProviderDocumentsUpdateWork with the document ids to be checked and updated if needed.

The @{link BlobProviderDocumentsUpdateWork} will then call the implementation of checkChangesAndUpdateBlob(List).

Note that it is recommended to schedule many workers dealing with a smaller amount of documents (using MAX_RESULT) rather than a single one processing all document brought by the provider.

Since:

7.3
