    • Method Detail

      • getCollection

        @Nullable
        public Collection getCollection()
        return the collection to which the document belongs.
        Returns:
        the document's collection
      • getId

        @NonNull
        public String getId()
        return the document's ID.
        Returns:
        the document's ID
      • getRevisionID

        @Nullable
        public String getRevisionID()
        Get the document's revision id. The revision id in the Document class is a constant while the revision id in the MutableDocument class is not. A newly created Document will have a null revision id. The revision id in a MutableDocument will be updated on save. The revision id format is opaque, which means its format has no meaning and shouldn't be parsed to get information.
        Returns:
        the document's revision id
      • getSequence

        public long getSequence()
        Return the sequence number of the document in the database. The sequence number indicates how recently the document has been changed. Every time a document is updated, the database assigns it the next sequential sequence number. Thus, when a document's sequence number changes it means that the document been updated (on-disk). If one document's sequence is different than another's, the document with the larger sequence number was changed more recently. Sequence numbers are not available for documents obtained from a replication filter. This method will always return 0 for such documents.
        Returns:
        the sequence number of the document in the database.
      • toMutable

        @NonNull
        public MutableDocument toMutable()
