Event aquery_trans_after

This event is used for representations, when a query facet is requested, on every line returned to fill a line of the query.

It can be used to assign properties that are not present in the tables or that have a different name so that the Setinstance instruction used to assign the class property will not work.

Available variables

• this.MYINST is defined and corresponds to the data class representing a line (MYINST being the instance name of the class defined in the representation).
• The tables present in the query are filled with the values of the current line. It can be the [LNK_] class if the class is an interface class, or the different tables present in the Link instruction.
• [L]ASTATUS can be set either to [V]CST_AOK if the line must be sent to the query result, or to another value ([V]CST_AERROR for instance) if it must not be sent to the query result. This allows notably to perform additional filtering that is not based on a single filter condition that could have been given on the query request.
