Method Details

executeFromState

protected StateMachineProcedure.Flow executeFromState(ConfigNodeProcedureEnv env,
 CreateRegionGroupsState state)

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,CreateRegionGroupsState>

state - state to execute

Returns:

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

rollbackState

protected void rollbackState(ConfigNodeProcedureEnv configNodeProcedureEnv,
 CreateRegionGroupsState createRegionGroupsState)

Description copied from class: StateMachineProcedure

Called to perform the rollback of the specified state.

Specified by:

rollbackState in class StateMachineProcedure<ConfigNodeProcedureEnv,CreateRegionGroupsState>

createRegionGroupsState - state to rollback

getState

protected CreateRegionGroupsState 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,CreateRegionGroupsState>

Parameters:

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

Returns:

the state enum object

getStateId

protected int getStateId(CreateRegionGroupsState createRegionGroupsState)

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<ConfigNodeProcedureEnv,CreateRegionGroupsState>

Parameters:

createRegionGroupsState - the state enum object

Returns:

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

getInitialState

protected CreateRegionGroupsState 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,CreateRegionGroupsState>

Returns:

the initial state enum object
