示例1: isMap
import com.espertech.esper.client.annotation.EventRepresentation; //导入依赖的package包/类
public static boolean isMap(Annotation[] annotations, ConfigurationInformation configs, CreateSchemaDesc.AssignedType assignedType) {
// assigned type has priority
if (assignedType == CreateSchemaDesc.AssignedType.OBJECTARRAY) {
return false;
}
if (assignedType == CreateSchemaDesc.AssignedType.MAP) {
return true;
}
if (assignedType == CreateSchemaDesc.AssignedType.VARIANT || assignedType != CreateSchemaDesc.AssignedType.NONE) {
throw new IllegalStateException("Not handled by event representation: " + assignedType);
}
// annotation has second priority
Annotation annotation = AnnotationUtil.findAnnotation(annotations, EventRepresentation.class);
if (annotation != null) {
EventRepresentation eventRepresentation = (EventRepresentation) annotation;
return !eventRepresentation.array();
}
// use engine-wide default
return configs.getEngineDefaults().getEventMeta().getDefaultEventRepresentation() == Configuration.EventRepresentation.MAP;
}
