startProcessInstanceByKey

public ProcessInstance startProcessInstanceByKey(String processDefinitionKey)

Description copied from interface: RuntimeService

Starts a new process instance in the latest version of the process definition with the given key.

Specified by:

startProcessInstanceByKey in interface RuntimeService

Parameters:

processDefinitionKey - key of process definition, cannot be null.

startProcessInstanceByKey

public ProcessInstance startProcessInstanceByKey(String processDefinitionKey,
                                        String businessKey)

Description copied from interface: RuntimeService

Starts a new process instance in the latest version of the process definition with the given key. A business key can be provided to associate the process instance with a certain identifier that has a clear business meaning. For example in an order process, the business key could be an order id. This business key can then be used to easily look up that process instance , see ProcessInstanceQuery.processInstanceBusinessKey(String). Providing such a business key is definitely a best practice. Note that a business key MUST be unique for the given process definition WHEN you have added a database constraint for it. In this case, only Process instance from different process definition are allowed to have the same business key and the combination of processdefinitionKey-businessKey must be unique.

Specified by:

startProcessInstanceByKey in interface RuntimeService

Parameters:

processDefinitionKey - key of process definition, cannot be null.

businessKey - a key that uniquely identifies the process instance in the context of the given process definition.

getActiveActivityIds

public List<String> getActiveActivityIds(String executionId)

Description copied from interface: RuntimeService

Finds the activity ids for all executions that are waiting in activities. This is a list because a single activity can be active multiple times.

Specified by:

getActiveActivityIds in interface RuntimeService

Parameters:

executionId - id of the process instance or the execution, cannot be null.

getActivityInstance

public ActivityInstance getActivityInstance(String processInstanceId)

Description copied from interface: RuntimeService

Allows retrieving the activity instance tree for a given process instance. The activity instance tree is aligned with the concept of scope in the BPMN specification. Activities that are "on the same level of subprocess" (ie. part of the same scope, contained in the same subprocess) will have their activity instances at the same level in the tree.

Examples:

• Process with two parallel user tasks after parallel Gateway: in the activity instance tree you will see two activity instances below the root instance, one for each user task.
• Process with two parallel Multi Instance user tasks after parallel Gateway: in the activity instance tree, all instances of both user tasks will be listed below the root activity instance. Reason: all activity instances are at the same level of subprocess.
• Usertask inside embedded subprocess: the activity instance three will have 3 levels: the root instance representing the process instance itself, below it an activity instance representing the instance of the embedded subprocess, and below this one, the activity instance representing the usertask.

Identity & Uniqueness:

Each activity instance is assigned a unique Id. The id is persistent, if you invoke this method multiple times, the same activity instance ids will be returned for the same activity instances. (However, there might be different executions assigned, see below)

Relation to Executions

The Execution concept in the process engine is not completely aligned with the activity instance concept because the execution tree is in general not aligned with the activity / scope concept in BPMN. In general, there is a n-1 relationship between Executions and ActivityInstances, ie. at a given point in time, an activity instance can be linked to multiple executions. In addition, it is not guaranteed that the same execution that started a given activity instance will also end it. The process engine performs several internal optimizations concerning the compacting of the execution tree which might lead to executions being reordered and pruned. This can lead to situations where a given execution starts an activity instance but another execution ends it. Another special case is the process instance: if the process instance is executing a non-scope activity (for example a user task) below the process definition scope, it will be referenced by both the root activity instance and the user task activity instance.

If you need to interpret the state of a process instance in terms of a BPMN process model, it is usually easier to use the activity instance tree as opposed to the execution tree.

Specified by:

getActivityInstance in interface RuntimeService

Parameters:

processInstanceId - the id of the process instance for which the activity instance tree should be constructed.

Returns:

the activity instance tree for a given process instance or null if no such process instance exists.

getFormInstanceById

public FormData getFormInstanceById(String processDefinitionId)

suspendProcessInstanceById

public void suspendProcessInstanceById(String processInstanceId)

Description copied from interface: RuntimeService

Suspends the process instance with the given id. This means that the execution is stopped, so the token state will not change. However, actions that do not change token state, like setting/removing variables, etc. will succeed.

Tasks belonging to this process instance will also be suspended. This means that any actions influencing the tasks' lifecycles will fail, such as

• claiming
• completing
• delegation
• changes in task assignees, owners, etc.

Actions that only change task properties will succeed, such as changing variables or adding comments.

If a process instance is in state suspended, the engine will also not execute jobs (timers, messages) associated with this instance.

If you have a process instance hierarchy, suspending one process instance from the hierarchy will not suspend other process instances from that hierarchy.

Specified by:

suspendProcessInstanceById in interface RuntimeService

suspendProcessInstanceByProcessDefinitionId

public void suspendProcessInstanceByProcessDefinitionId(String processDefinitionId)

Description copied from interface: RuntimeService

Suspends the process instances with the given process definition id. This means that the execution is stopped, so the token state will not change. However, actions that do not change token state, like setting/removing variables, etc. will succeed.

Tasks belonging to the suspended process instance will also be suspended. This means that any actions influencing the tasks' lifecycles will fail, such as

• claiming
• completing
• delegation
• changes in task assignees, owners, etc.

Actions that only change task properties will succeed, such as changing variables or adding comments.

If a process instance is in state suspended, the engine will also not execute jobs (timers, messages) associated with this instance.

If you have a process instance hierarchy, suspending one process instance from the hierarchy will not suspend other process instances from that hierarchy.

Specified by:

suspendProcessInstanceByProcessDefinitionId in interface RuntimeService

suspendProcessInstanceByProcessDefinitionKey

public void suspendProcessInstanceByProcessDefinitionKey(String processDefinitionKey)

Description copied from interface: RuntimeService

• claiming
• completing
• delegation
• changes in task assignees, owners, etc.

Actions that only change task properties will succeed, such as changing variables or adding comments.

If a process instance is in state suspended, the engine will also not execute jobs (timers, messages) associated with this instance.
