                                  boolean userData,
                                  java.util.HashMap focusvalues,
                                  java.util.ArrayList requestedData,
                                  ca_db simdb,
                                  PlanSet plans,

the stack of results

toStack

public static stackp toStack(java.lang.String queryname,
                             BackEndResult ber,
                             PlanSet plans)

This functions converts a HopsAttribute array to stack of attrval. In case of the SearchEvent, to stack of one attrval with an arraylist with all the results!!! This is an attrval named event, with an extension of "pag", and instead of having a list of values, it has a list of results. Its value is the number of attrval in the results. This list of results is a list of attrval where each attrval is an event. Each event name is the exequery name, and has a list of result. Each result is an attrval with a property of the event: participant, title, location, etc...

Parameters:

queryname - the name of BE query

ber - the BackEndResults of HopsAttributes

Returns:

the stack of attributes
