                                     throws org.apache.olingo.server.api.ODataApplicationException

Applies server-side paging to the given entity collection.

The next link is constructed and set in the data. It must support client-specified page sizes. Therefore, the format page*pageSize (with a literal asterisk) has been chosen for the skiptoken.

Parameters:

skipTokenOption - the current skiptoken option (from a previous response's next link)

entityCollection - the data

edmEntitySet - the EDM entity set to decide whether paging must be done

rawRequestUri - the request URI (used to construct the next link)

preferredPageSize - the client's preference for page size

Returns:

the chosen page size (or null if no paging has been done); could be used in the Preference-Applied HTTP header

Throws:

org.apache.olingo.server.api.ODataApplicationException
