示例1: createSingleEntryDatabase
import javax.persistence.criteria.Root; //导入方法依赖的package包/类
protected void createSingleEntryDatabase() throws Exception {
VirtualDatabase newVDB = this.database.getClone();
Map<String, Objectref> createdObjectEntityMap = new HashMap<>();
for(Root<?> root : this.criteriaQuery.getRoots()) {
String rootClassName = root.getJavaType().getName();
EntityEntry rootEntityEntry = EntityAnalyzer.getInitialEntityEntry(rootClassName);
Objectref rootObjectref = getObjectrefByEntityEntry(rootClassName, rootEntityEntry);
createdObjectEntityMap.put(rootClassName, rootObjectref);
newVDB.addRequired(rootObjectref.getObjectId(), rootEntityEntry);
newVDB.addData(rootObjectref);
for(Join<?,?> join : root.getJoins()) {
handleJoin(newVDB, createdObjectEntityMap, join, rootObjectref);
}
}
String result = criteriaQuery.getResultType().getName();
Objectref singleObjectElement = createdObjectEntityMap.get(result);
Objectref singleResultListObjRef = getArrayListObjectref();
addObjectrefToArrayList(singleResultListObjRef, singleObjectElement);
SolverManager solverManager = ((SymbolicVirtualMachine) frame.getVm()).getSolverManager();
