//*-- Author : Damir Buskulic 11/07/00//////////////////////////////////////////////////////////////////////////// //// VConditionSet //// //// Class for managing sets of conditions, i.e. conditions //// that may have overlap(s) in time. //// A condition set is used as a selection and a pointer to a particular //// point in time where the selection expression is verified. //// It is used in sequential access of frames or vectors satisfying some //// conditions. Suppose for example that one wants to access all the //// frames that have triggered the condition "Trig3.amplitude>3", where //// Trig3 is a condition (or trigger) defined in the frames. //// If vd is a pointer to a valid info database containing //// the information, one would do : //// //// vega[] co = new VConditionSet(vd,"Trig3.amp>3") //// vega[] fr = frchannel->GetNextFrame(co) //// //// that would return him the first frame satisfying the condition. //// Issueing fr = frchannel->GetNextFrame(co) repeatedly will return //// sequentialy all the frames that satisfy the condition. //// ////////////////////////////////////////////////////////////////////////////
