Description copied from interface: SelectExprProcessor

Computes the select-clause results and returns an event of the result event type that contains, in it's properties, the selected items.

Specified by:

process in interface SelectExprProcessor

Parameters:

eventsPerStream - - is per stream the event

isNewData - - indicates whether we are dealing with new data (istream) or old data (rstream)

isSynthesize - - set to true to indicate that synthetic events are required for an iterator result set

exprEvaluatorContext - context

Returns:

event with properties containing selected items
