    • addTopSkip

      protected void addTopSkip​(javax.persistence.TypedQuery<javax.persistence.Tuple> tq) throws org.apache.olingo.server.api.ODataApplicationException
      Applies the $skip and $top options of the OData request to the query. The values are defined as follows:
      • The $top system query option specifies a non-negative integer n that limits the number of items returned from a collection.
      • The $skip system query option specifies a non-negative integer n that excludes the first n items of the queried collection from the result.
      These values can be restricted by a page provided by server driven paging

      For details see: OData Version 4.0 Part 1 - 11.2.5.3 System Query Option $top and OData Version 4.0 Part 1 - 11.2.5.7 Server-Driven Paging
