Modifier and Type | Method and Description |
---|---|
protected void |
deserializeStateData(ProcedureStateSerializer serializer)
Called on store load to allow the user to decode the previously serialized
state.
|
protected StateMachineProcedure.Flow |
executeFromState(MasterProcedureEnv env,
MasterProcedureProtos.ModifyNamespaceState state)
called to perform a single step of the specified 'state' of the procedure
|
protected MasterProcedureProtos.ModifyNamespaceState |
getInitialState()
Return the initial state object that will be used for the first call to executeFromState().
|
protected String |
getNamespaceName() |
protected MasterProcedureProtos.ModifyNamespaceState |
getState(int stateId)
Convert an ordinal (or state id) to an Enum (or more descriptive) state object.
|
protected int |
getStateId(MasterProcedureProtos.ModifyNamespaceState state)
Convert the Enum (or more descriptive) state object to an ordinal (or state id).
|
TableProcedureInterface.TableOperationType |
getTableOperationType()
Given an operation type we can take decisions about what to do with pending operations.
|
protected boolean |
isRollbackSupported(MasterProcedureProtos.ModifyNamespaceState state)
Used by the default implementation of abort() to know if the current state can be aborted
and rollback can be triggered.
|
protected void |
rollbackState(MasterProcedureEnv env,
MasterProcedureProtos.ModifyNamespaceState state)
called to perform the rollback of the specified state
|
protected void |
serializeStateData(ProcedureStateSerializer serializer)
The user-level code of the procedure may have some state to
persist (e.g.
