示例1: initializeData
import com.orientechnologies.orient.core.db.document.ODatabaseDocumentTx; //导入方法依赖的package包/类
@Override
public void initializeData() {
// Important! method is called without transaction to let implementation control transaction scope and type
// (initializer may even use many (different?) transactions).
// Unit of work must be defined before calling orient api: the simplest way is to use @Transactional
// on class or method
final ODatabaseDocumentTx db = context.getConnection();
if (db.countClass(ManualSchemeInitializer.CLASS_NAME) > 0) {
// perform initialization only in case of empty table
return;
}
// low level api used to insert records, but the same could be done with sql insert commands
for (int i = 0; i < 10; i++) {
final ODocument rec = db.newInstance(ManualSchemeInitializer.CLASS_NAME)
.field("name", "Sample" + i)
.field("amount", (int) (Math.random() * 200));
rec.save();
}
}
示例2: execute
import com.orientechnologies.orient.core.db.document.ODatabaseDocumentTx; //导入方法依赖的package包/类
public long execute(final ODatabaseDocumentTx db) {
checkNotNull(db);
return db.countClass(type);
