Types

type BaseStore

type BaseStore struct {
	// contains filtered or unexported fields
}

BaseStore 基础的store结构体

func NewBaseStore(cfg *types.Store) *BaseStore

NewBaseStore new base store struct

func (*BaseStore) Close

func (store *BaseStore) Close()

Close 关闭BaseStore 相关资源包括数据库、client等

func (*BaseStore) GetDB

func (store *BaseStore) GetDB() dbm.DB

GetDB 返回 store db

func (*BaseStore) GetQueueClient

func (store *BaseStore) GetQueueClient() queue.Client

GetQueueClient 返回store模块的client

func (*BaseStore) SetChild

func (store *BaseStore) SetChild(sub SubStore)

SetChild 设置BaseStore中的子存储参数

func (*BaseStore) SetQueueClient

func (store *BaseStore) SetQueueClient(c queue.Client)

SetQueueClient set client queue for recv msg

func (*BaseStore) Wait

func (store *BaseStore) Wait()

Wait wait for basestore ready

type Storecreate

type Storecreate func(cfg *types.Store, sub []byte, chain33cfg *types.Chain33Config) queue.Module

Storecreate store queue module

func Load

func Load(name string) (create Storecreate, err error)

Load load StoreCreate by name

type StorelistQuery

type StorelistQuery struct {
	*types.StoreListReply
	// contains filtered or unexported fields
}

StorelistQuery defines a type store list query

func NewStoreListQuery

func NewStoreListQuery(store SubStore, req *types.StoreList) *StorelistQuery

NewStoreListQuery new store list query object

func (*StorelistQuery) IterateCallBack

func (t *StorelistQuery) IterateCallBack(key, value []byte) bool

IterateCallBack store list query iterate callback

func (*StorelistQuery) Run

func (t *StorelistQuery) Run() *types.StoreListReply

Run store list query

type SubStore

type SubStore interface {
	Set(datas *types.StoreSet, sync bool) ([]byte, error)
	Get(datas *types.StoreGet) [][]byte
	MemSet(datas *types.StoreSet, sync bool) ([]byte, error)
	Commit(hash *types.ReqHash) ([]byte, error)
	Rollback(req *types.ReqHash) ([]byte, error)
	Del(req *types.StoreDel) ([]byte, error)
	IterateRangeByStateHash(statehash []byte, start []byte, end []byte, ascending bool, fn func(key, value []byte) bool)
	ProcEvent(msg *queue.Message)

	//用升级本地交易构建store
	MemSetUpgrade(datas *types.StoreSet, sync bool) ([]byte, error)
	CommitUpgrade(hash *types.ReqHash) ([]byte, error)
}
