Usage

From source file:com.espertech.esper.epl.core.ResultSetProcessorSimple.java

/**
 * Applies the select-clause to the given events returning the selected events. The number of events stays the
 * same, i.e. this method does not filter it just transforms the result set.
 * <p>/* w  w w . j a v  a2s.com*/
 * Also applies a having clause.
 * @param exprProcessor - processes each input event and returns output event
 * @param events - input events
 * @param optionalHavingNode - supplies the having-clause expression
 * @param isNewData - indicates whether we are dealing with new data (istream) or old data (rstream)
 * @param isSynthesize - set to true to indicate that synthetic events are required for an iterator result set
 * @param exprEvaluatorContext context for expression evalauation
 * @return output events, one for each input event
