Android数据缓存框架内置ORM功能使用教程

Orm.init(this, OrmConfig.Builder()
                .database("dcache_sample")
                .tables(Account::class.java)
                .version(1)
                .build())

DaoFactory.getDao(Account::class.java).insert(Account(generateAccKey(),
                    "D"+generateAccKey(), "P"+generateAccKey()))

val selectOne = DaoFactory.getDao(Account::class.java)
                    .selectOne(QueryBuilder.create().orderBy(OrmTable.INDEX_ID))
            if (selectOne != null) {
                DaoFactory.getDao(Account::class.java).delete(selectOne)
            }

DaoFactory.getDao(Account::class.java).update(Account("这个是key",
                    "D"+generateAccKey(), "P"+generateAccKey()))

public WhereBuilder addWhereEqualTo(String column, Object value) {
        return append(null, column + EQUAL_HOLDER, value);
    }

val count = DaoFactory.getDao(Account::class.java).selectCount()

@Convert(converter = StringListConverter.class, columnType = String.class)
@Column("acc_child_values")
private List<String> accChildValues;

  @Override
  public boolean isUpgradeRecreated() {
      return false;
  }

Transaction.execute(Account::class.java) {
                val selectOne = 			it.selectOne(QueryBuilder.create().orderBy(OrmTable.INDEX_ID))
                if (selectOne != null) {
