Constructor Details

StateMachineTransitionBuilder

public StateMachineTransitionBuilder()

Instantiates a new state machine transition builder.

StateMachineTransitionBuilder

public StateMachineTransitionBuilder(ObjectPostProcessor<Object> objectPostProcessor,
 boolean allowConfigurersOfSameType)

Instantiates a new state machine transition builder.

Parameters:

objectPostProcessor - the object post processor

allowConfigurersOfSameType - the allow configurers of same type

StateMachineTransitionBuilder

public StateMachineTransitionBuilder(ObjectPostProcessor<Object> objectPostProcessor)

Instantiates a new state machine transition builder.

Parameters:

objectPostProcessor - the object post processor

Method Details

performBuild

protected TransitionsData<S,E> performBuild()
                                     throws Exception

Description copied from class: AbstractConfiguredAnnotationBuilder

Subclasses must implement this method to build the object that is being returned.

Specified by:

performBuild in class AbstractConfiguredAnnotationBuilder<TransitionsData<S,E>,StateMachineTransitionConfigurer<S,E>,StateMachineTransitionBuilder<S,E>>

Returns:

Object build by this builder

Throws:

Exception - if error occurred

withExternal

public ExternalTransitionConfigurer<S,E> withExternal()
                                               throws Exception

Description copied from interface: StateMachineTransitionConfigurer

Gets a configurer for external transition.

Specified by:

withExternal in interface StateMachineTransitionConfigurer<S,E>

Returns:

ExternalTransitionConfigurer for chaining

Throws:

Exception - if configuration error happens

withInternal

public InternalTransitionConfigurer<S,E> withInternal()
                                               throws Exception

Description copied from interface: StateMachineTransitionConfigurer

Gets a configurer for internal transition. Internal transition is used when action needs to be executed without causing a state transition. With internal transition source and target state is always a same and it is identical with self-transition in the absence of state entry and exit actions.

Specified by:

withInternal in interface StateMachineTransitionConfigurer<S,E>

Returns:

InternalTransitionConfigurer for chaining

Throws:

Exception - if configuration error happens

withLocal

public LocalTransitionConfigurer<S,E> withLocal()
                                         throws Exception

Description copied from interface: StateMachineTransitionConfigurer

Gets a configurer for local transition. Local transition doesn’t cause exit and entry to source state if target state is a substate of a source state. Other way around, local transition doesn’t cause exit and entry to target state if target is a superstate of a source state.

Specified by:

withLocal in interface StateMachineTransitionConfigurer<S,E>

Returns:

LocalTransitionConfigurer for chaining

Throws:

Exception - if configuration error happens

withChoice

public ChoiceTransitionConfigurer<S,E> withChoice()
                                           throws Exception

Description copied from interface: StateMachineTransitionConfigurer

Gets a configurer for transition from a choice pseudostate.

Specified by:

withChoice in interface StateMachineTransitionConfigurer<S,E>

Returns:

ChoiceTransitionConfigurer for chaining

Throws:

Exception - if configuration error happens

withJunction

public JunctionTransitionConfigurer<S,E> withJunction()
                                               throws Exception

Description copied from interface: StateMachineTransitionConfigurer

Gets a configurer for transition from a junction pseudostate.

Specified by:

withJunction in interface StateMachineTransitionConfigurer<S,E>

Returns:

JunctionTransitionConfigurer for chaining

Throws:

Exception - if configuration error happens

withFork

                                       throws Exception

Description copied from interface: StateMachineTransitionConfigurer

Gets a configurer for transition from a fork pseudostate.

Specified by:

withFork in interface StateMachineTransitionConfigurer<S,E>

Returns:

ForkTransitionConfigurer for chaining

Throws:

Exception - if configuration error happens

withJoin

public JoinTransitionConfigurer<S,E> withJoin()
                                       throws Exception

Description copied from interface: StateMachineTransitionConfigurer

Gets a configurer for transition from a join pseudostate.

Specified by:
