Method Detail

cancelActivityInstance

public ProcessInstanceModificationBuilder cancelActivityInstance(String activityInstanceId)

Description copied from interface: ProcessInstanceModificationBuilder

Submits the instruction:

Cancel an activity instance in a process. If this instance has child activity instances (e.g. in a subprocess instance), these children, their grandchildren, etc. are cancelled as well.

Process instance cancellation will propagate upward, removing any parent process instances that are only waiting on the cancelled process to complete.

Specified by:

cancelActivityInstance in interface ProcessInstanceModificationBuilder

Parameters:

activityInstanceId - the id of the activity instance to cancel

cancelTransitionInstance

public ProcessInstanceModificationBuilder cancelTransitionInstance(String transitionInstanceId)

Description copied from interface: ProcessInstanceModificationBuilder

Submits the instruction:

Cancel a transition instance (i.e. an async continuation) in a process.

Specified by:

cancelTransitionInstance in interface ProcessInstanceModificationBuilder

Parameters:

transitionInstanceId - the id of the transition instance to cancel

cancelAllForActivity

public ProcessInstanceModificationBuilder cancelAllForActivity(String activityId)

Description copied from interface: ProcessInstanceModificationBuilder

Submits the instruction:

Cancel all instances of the given activity in an arbitrary order, which are:

• activity instances of that activity
• transition instances entering or leaving that activity

Therefore behaves like ProcessInstanceModificationBuilder.cancelActivityInstance(String) for each individual activity instance and like ProcessInstanceModificationBuilder.cancelTransitionInstance(String) for each individual transition instance.

The cancellation order of the instances is arbitrary

Specified by:

cancelAllForActivity in interface ProcessInstanceModificationBuilder

Parameters:

activityId - the activity for which all instances should be cancelled

startBeforeActivity

public ProcessInstanceModificationInstantiationBuilder startBeforeActivity(String activityId)

Description copied from interface: InstantiationBuilder

Submits the instruction:

Start before the specified activity.

In particular:

• In the parent activity hierarchy, determine the closest existing ancestor activity instance
• Instantiate all parent activities up to the ancestor's activity
• Instantiate and execute the given activity (respects the asyncBefore attribute of the activity)

Specified by:

startBeforeActivity in interface InstantiationBuilder<ProcessInstanceModificationInstantiationBuilder>

Parameters:

activityId - the activity to instantiate

startBeforeActivity

public ProcessInstanceModificationInstantiationBuilder startBeforeActivity(String activityId,
                                                                           String ancestorActivityInstanceId)

Description copied from interface: ProcessInstanceModificationBuilder

Submits the instruction:

Start before the specified activity. Instantiate the given activity as a descendant of the given ancestor activity instance.

In particular:

• Instantiate all activities between the ancestor activity and the activity to execute
• Instantiate and execute the given activity (respects the asyncBefore attribute of the activity)

Specified by:

startBeforeActivity in interface ProcessInstanceModificationBuilder

Parameters:

activityId - the activity to instantiate

ancestorActivityInstanceId - the ID of an existing activity instance under which the new activity instance should be created

startAfterActivity

public ProcessInstanceModificationInstantiationBuilder startAfterActivity(String activityId)

Description copied from interface: InstantiationBuilder

Submits an instruction that behaves like InstantiationBuilder.startTransition(String) and always instantiates the single outgoing sequence flow of the given activity. Does not consider asyncAfter.

Specified by:

startAfterActivity in interface InstantiationBuilder<ProcessInstanceModificationInstantiationBuilder>

Parameters:

activityId - the activity for which the outgoing flow should be executed

startAfterActivity

public ProcessInstanceModificationInstantiationBuilder startAfterActivity(String activityId,
                                                                          String ancestorActivityInstanceId)

Description copied from interface: ProcessInstanceModificationBuilder

Submits an instruction that behaves like ProcessInstanceModificationBuilder.startTransition(String,String) and always instantiates the single outgoing sequence flow of the given activity. Does not consider asyncAfter.

Specified by:

startAfterActivity in interface ProcessInstanceModificationBuilder

Parameters:

activityId - the activity for which the outgoing flow should be executed

startTransition

public ProcessInstanceModificationInstantiationBuilder startTransition(String transitionId)

Description copied from interface: InstantiationBuilder

Submits the instruction:

Start a sequence flow.

In particular:

• In the parent activity hierarchy, determine the closest existing ancestor activity instance
• Instantiate all parent activities up to the ancestor's activity
• Execute the given transition (does not consider sequence flow conditions)

Specified by:

startTransition in interface InstantiationBuilder<ProcessInstanceModificationInstantiationBuilder>

Parameters:

transitionId - the sequence flow to execute

startTransition

public ProcessInstanceModificationInstantiationBuilder startTransition(String transitionId,
                                                                       String ancestorActivityInstanceId)

Description copied from interface: ProcessInstanceModificationBuilder

Submits the instruction:

Start the specified sequence flow. Instantiate the given sequence flow as a descendant of the given ancestor activity instance.

In particular:

• Instantiate all activities between the ancestor activity and the activity to execute
• Execute the given transition (does not consider sequence flow conditions)

Specified by:

startTransition in interface ProcessInstanceModificationBuilder
