serializeStateData

protected void serializeStateData(ProcedureStateSerializer serializer)
                           throws IOException

Description copied from class: Procedure

The user-level code of the procedure may have some state to persist (e.g. input arguments or current position in the processing state) to be able to resume on failure.

Overrides:

serializeStateData in class AbstractPeerNoLockProcedure<org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.PeerSyncReplicationStateTransitionState>

Parameters:

serializer - stores the serializable state

Throws:

IOException

deserializeStateData

protected void deserializeStateData(ProcedureStateSerializer serializer)
                             throws IOException

Description copied from class: Procedure

Called on store load to allow the user to decode the previously serialized state.

Overrides:

deserializeStateData in class AbstractPeerNoLockProcedure<org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.PeerSyncReplicationStateTransitionState>

Parameters:

serializer - contains the serialized state

Throws:

IOException

getState

protected org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.PeerSyncReplicationStateTransitionState getState(int stateId)

Description copied from class: StateMachineProcedure

Convert an ordinal (or state id) to an Enum (or more descriptive) state object.

Specified by:

getState in class StateMachineProcedure<MasterProcedureEnv,org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.PeerSyncReplicationStateTransitionState>

Parameters:

stateId - the ordinal() of the state enum (or state id)

Returns:

the state enum object

getStateId

protected int getStateId(org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.PeerSyncReplicationStateTransitionState state)

Description copied from class: StateMachineProcedure

Convert the Enum (or more descriptive) state object to an ordinal (or state id).

Specified by:

getStateId in class StateMachineProcedure<MasterProcedureEnv,org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.PeerSyncReplicationStateTransitionState>

Parameters:

state - the state enum object

Returns:

stateId the ordinal() of the state enum (or state id)

getInitialState

protected org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.PeerSyncReplicationStateTransitionState getInitialState()

Description copied from class: StateMachineProcedure

Specified by:

getInitialState in class StateMachineProcedure<MasterProcedureEnv,org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.PeerSyncReplicationStateTransitionState>

Returns:

the initial state enum object
