示例1: trySource
import com.espertech.esper.client.dataflow.EPDataFlowInstantiationOptions; //导入方法依赖的package包/类
private void trySource(AdapterInputSource source) throws Exception {
CSVInputAdapterSpec spec = new CSVInputAdapterSpec(source, "TypeC");
epService = EPServiceProviderManager.getProvider("testPlayFromInputStream", makeConfig("TypeC"));
epService.initialize();
InputAdapter feed = new CSVInputAdapter(epService, spec);
EPStatement stmt = epService.getEPAdministrator().createEPL("select * from TypeC#length(100)");
SupportUpdateListener listener = new SupportUpdateListener();
stmt.addListener(listener);
feed.start();
assertEquals(1, listener.getNewDataList().size());
if (source.getAsReader() != null) {
source.getAsReader().reset();
} else {
source.getAsStream().reset();
}
// test graph
String graph = "create dataflow ReadCSV " +
"FileSource -> mystream<TypeC> { hasTitleLine: true, classpathFile: true }" +
