方法详细资料

newProcedure

public static Procedure newProcedure(String className)
                              throws BadProcedureException

抛出:

BadProcedureException

validateClass

public static void validateClass(Procedure proc)
                          throws BadProcedureException

抛出:

BadProcedureException

convertToProtoProcedure

public static ProcedureProtos.Procedure convertToProtoProcedure(Procedure proc)
                                                         throws IOException

Helper to convert the procedure to protobuf. Used by ProcedureStore implementations.

抛出:

IOException

convertToProcedure

public static Procedure convertToProcedure(ProcedureProtos.Procedure proto)
                                    throws IOException

Helper to convert the protobuf procedure. Used by ProcedureStore implementations. TODO: OPTIMIZATION: some of the field never change during the execution (e.g. className, procId, parentId, ...). We can split in 'data' and 'state', and the store may take advantage of it by storing the data only on insert().

抛出:

IOException

convertToProtoResourceType

public static LockServiceProtos.LockedResourceType convertToProtoResourceType(LockedResourceType resourceType)

convertToProtoLockType

public static LockServiceProtos.LockType convertToProtoLockType(LockType lockType)

convertToProtoLockedResource

public static LockServiceProtos.LockedResource convertToProtoLockedResource(LockedResource lockedResource)
                                                                     throws IOException

抛出:

IOException
