executeFromState

protected StateMachineProcedure.Flow executeFromState(ConfigNodeProcedureEnv env,
 Integer state)
                                               throws InterruptedException

Description copied from class: StateMachineProcedure

Called to perform a single step of the specified 'state' of the procedure.

Specified by:

executeFromState in class StateMachineProcedure<ConfigNodeProcedureEnv,Integer>

state - state to execute

Returns:

Flow.NO_MORE_STATE if the procedure is completed, Flow.HAS_MORE_STATE if there is another step.

Throws:

InterruptedException

rollbackState

protected void rollbackState(ConfigNodeProcedureEnv configNodeProcedureEnv,
 Integer state)
                      throws IOException,
InterruptedException,
ProcedureException

Description copied from class: StateMachineProcedure

Called to perform the rollback of the specified state.

Specified by:

rollbackState in class StateMachineProcedure<ConfigNodeProcedureEnv,Integer>

state - state to rollback

Throws:

IOException - temporary failure, the rollback will retry later

InterruptedException

ProcedureException

getState

protected Integer 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<ConfigNodeProcedureEnv,Integer>

Parameters:

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

Returns:

the state enum object

getStateId

protected int getStateId(Integer integer)

Description copied from class: StateMachineProcedure

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

Specified by:

Parameters:

integer - the state enum object

Returns:

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

getInitialState

protected Integer getInitialState()

Description copied from class: StateMachineProcedure

Return the initial state object that will be used for the first call to executeFromState().

Specified by:

getInitialState in class StateMachineProcedure<ConfigNodeProcedureEnv,Integer>

Returns:

the initial state enum object
