示例1: determineOnExprView

import com.espertech.esper.core.start.EPStatementStartMethodHelperUtil; //导入依赖的package包/类
public OnExprViewResult determineOnExprView(AgentInstanceContext agentInstanceContext, List<StopCallback> stopCallbacks, boolean isRecoveringReslient) {
    OnTriggerWindowDesc onTriggerWindowDesc = (OnTriggerWindowDesc) statementSpec.getOnTriggerDesc();

    // get result set processor and aggregation services
    Pair<ResultSetProcessor, AggregationService> pair = EPStatementStartMethodHelperUtil.startResultSetAndAggregation(resultSetProcessorPrototype, agentInstanceContext, false, null);

    TableStateInstance state = services.getTableService().getState(onTriggerWindowDesc.getWindowName(), agentInstanceContext.getAgentInstanceId());
    EventTable[] indexes;
    if (queryPlanResult.getIndexDescs() == null) {
        indexes = null;
    } else {
        indexes = new EventTable[queryPlanResult.getIndexDescs().length];
        for (int i = 0; i < indexes.length; i++) {
            indexes[i] = state.getIndexRepository().getIndexByDesc(queryPlanResult.getIndexDescs()[i].getIndexMultiKey());
        }
    }
    SubordWMatchExprLookupStrategy strategy = queryPlanResult.getFactory().realize(indexes, agentInstanceContext, state.getIterableTableScan(), null);
    TableOnView onExprBaseView = onExprFactory.make(strategy, state, agentInstanceContext, pair.getFirst());

    return new OnExprViewResult(onExprBaseView, pair.getSecond());
