限定符和类型	方法和说明
protected List<EventSourceWrapper>	QueueMiddleComponent._peek(int bulkSize)
protected void	QueueMiddleComponent.batchDelete(long pageNo, int index, String... keys)
void	LevelDBPersistenceAdapter.deleteById(String[] ids)
<T> T	LevelDBPersistenceAdapter.get(String key, Class<T> type)
<T> T	QueueMiddleComponent.get(String key, Class<T> type)
<T> List<T>	LevelDBPersistenceAdapter.getMore(Class<T> type, String... keys)
void	LevelDBPersistenceAdapter.houseKeeping()
void	LevelDBQueue.houseKeeping()
void	QueueMiddleComponent.houseKeeping()
List<EventSourceWrapper>	LevelDBPersistenceAdapter.list(int batchSize)
List<EventSourceWrapper>	LevelDBPersistenceAdapter.list(int batchSize, org.iq80.leveldb.DBIterator iterator)
void	QueueMiddleComponent.load() load page info, read,write and delete cursor
protected void	QueueMiddleComponent.loadCursor()
protected void	QueueMiddleComponent.loadPage()
EventSourceWrapper	QueueMiddleComponent.peek() return the head data, but not move read cursor
List<EventSourceWrapper>	QueueMiddleComponent.peek(int bulkSize)
EventSourceWrapper	QueueMiddleComponent.pop() return the head data, and move read cursor ahead. if read cursor equals write cursor, it would return null.
List<EventSourceWrapper>	QueueMiddleComponent.pop(int bulkSize)
List<EventSourceWrapper>	QueueMiddleComponent.pop(int bulkSize, org.iq80.leveldb.WriteBatch wb) return a batch head data, and move read cursor ahead. if read cursor equals write cursor, it would return min size data.
EventSourceWrapper	QueueMiddleComponent.pop(org.iq80.leveldb.WriteBatch wb)
void	LevelDBPersistenceAdapter.put(String key, Serializable ser)
protected void	QueueMiddleComponent.put(String key, Serializable ser)
void	LevelDBPersistenceAdapter.put(String key, Serializable ser, org.iq80.leveldb.WriteBatch update)
protected void	QueueMiddleComponent.put(String key, Serializable ser, org.iq80.leveldb.WriteBatch update)
protected void	QueueMiddleComponent.put(org.iq80.leveldb.WriteBatch wb, String key, Serializable ser)
String	LevelDBPersistenceAdapter.save(CommonEventSource evt) 存储的key使用的是txnId，value为txn的字节流
String	QueueMiddleComponent.save(CommonEventSource evt)

eventcenter.leveldb.cache中PersistenceException的使用

抛出PersistenceException的eventcenter.leveldb.cache中的方法

限定符和类型	方法和说明
<T> T	LevelDBCache.get(String key, Class<T> type) 获取key的值
void	LevelDBCache.put(Map<String,Serializable> keyValues)
void	LevelDBCache.put(String key, Serializable value) 设置多个key的值
void	LevelDBCache.remove(String... keys)

抛出PersistenceException的eventcenter.leveldb.cache中的构造器

构造器和说明
LevelDBCache(String namespace, LevelDBPersistenceAdapter adapter)
