Method Detail

startProcessInstanceByKey

ProcessInstance startProcessInstanceByKey(String processDefinitionKey)
Starts a new process instance in the latest version of the process definition with the given key.

Parameters:
processDefinitionKey - key of process definition, cannot be null.
Throws:
ProcessEngineException - when no process definition is deployed with the given key.

startProcessInstanceByKey

ProcessInstance startProcessInstanceByKey(String processDefinitionKey,
                                          String businessKey)
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.

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.

Throws:
ProcessEngineException - when no execution exists with the given executionId.

getActivityInstance

ActivityInstance getActivityInstance(String processInstanceId)

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:

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.

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.
Throws:
ProcessEngineException - if processInstanceId is 'null' or an internal error occurs.
