NoopProcedureStore

public NoopProcedureStore()

方法详细资料

start

public void start(int numThreads)
           throws IOException

从接口复制的说明: ProcedureStore

Start/Open the procedure store

抛出:

IOException

stop

public void stop(boolean abort)

从接口复制的说明: ProcedureStore

Stop/Close the procedure store

参数:

abort - true if the stop is an abort

recoverLease

public void recoverLease()
                  throws IOException

从接口复制的说明: ProcedureStore

Acquire the lease for the procedure store.

抛出:

IOException

getNumThreads

public int getNumThreads()

返回:

the number of threads/slots passed to start()

load

public void load(ProcedureStore.ProcedureLoader loader)
          throws IOException

从接口复制的说明: ProcedureStore

Load the Procedures in the store.

参数:

loader - the ProcedureLoader that will handle the store-load events

抛出:

IOException

insert

public void insert(Procedure proc,
          Procedure[] subprocs)

从接口复制的说明: ProcedureStore

When a procedure is submitted to the executor insert(proc, null) will be called. 'proc' has a 'RUNNABLE' state and the initial information required to start up. When a procedure is executed and it returns children insert(proc, subprocs) will be called. 'proc' has a 'WAITING' state and an update state. 'subprocs' are the children in 'RUNNABLE' state with the initial information.

参数:

proc - the procedure to serialize and write to the store.

subprocs - the newly created child of the proc.

update

public void update(Procedure proc)

从接口复制的说明: ProcedureStore

The specified procedure was executed, and the new state should be written to the store.

参数:

proc - the procedure to serialize and write to the store.

delete

public void delete(long procId)

从接口复制的说明: ProcedureStore

The specified procId was removed from the executor, due to completion, abort or failure. The store implementor should remove all the information about the specified procId.

参数:

procId - the ID of the procedure to remove.

delete

public void delete(Procedure proc,
          long[] subprocs)

从接口复制的说明: ProcedureStore

The parent procedure completed. Update the state and mark all the child deleted.

参数:

proc - the parent procedure to serialize and write to the store.

subprocs - the IDs of the sub-procedure to remove.
