Ruby PStore.commit用法及代码示例

commit()

结束当前 PStore#transaction ，立即提交对数据存储的任何更改。

例子：

require "pstore"

store = PStore.new("data_file.pstore")
store.transaction do  # begin transaction
  # load some data into the store...
  store[:one] = 1
  store[:two] = 2

  store.commit        # end transaction here, committing changes

  store[:three] = 3   # this change is never reached
end

警告：此方法仅在 PStore#transaction 中有效。如果在任何其他时间调用，它将引发 PStore::Error 。
