Method Detail

executeFromState

protected StateMachineProcedure.Flow executeFromState(MasterProcedureEnv env,
                                          MasterProcedureProtos.CreateTableState state)

Specified by:

Throws:

IOException

getState

protected MasterProcedureProtos.CreateTableState getState(int stateId)

Specified by:

getState in class StateMachineProcedure<MasterProcedureEnv,MasterProcedureProtos.CreateTableState>

getStateId

protected int getStateId(MasterProcedureProtos.CreateTableState state)

Specified by:

getTableName

public TableName getTableName()

Specified by:

getTableName in interface TableProcedureInterface

Returns:

the name of the table the procedure is operating on

getTableOperationType

public TableProcedureInterface.TableOperationType getTableOperationType()

Description copied from interface: 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.

Specified by:

getTableOperationType in interface TableProcedureInterface

Returns:

the operation type that the procedure is executing.
