说明
java updateui示例是从最受好评的开源项目中提取的实现代码，你可以参考下面示例的使用方式。
编程语言: Java
类/类型: UpdateUI
示例#1
/** Runs check on the prior schema version, and then upgrades. */
private void upgradeFrom(UpdateUI ui, CurrentSchemaVersion curr, ReviewDb db)
throws OrmException, SQLException {
List<SchemaVersion> pending = pending(curr.versionNbr);
updateSchema(pending, ui, db);
