方法详细资料

getTableOperationType

public TableProcedureInterface.TableOperationType getTableOperationType()

从接口复制的说明: TableProcedureInterface

Given an operation type we can take decisions about what to do with pending operations. e.g. if we get a delete and we have some table operation pending (e.g. add column) we can abort those operations.

返回:

the operation type that the procedure is executing.

newRemoteOperation

public RemoteProcedureDispatcher.RemoteOperation newRemoteOperation()

抛出:

IOException

deserializeStateData

protected void deserializeStateData(ProcedureStateSerializer serializer)
