Interface CorrelationAwareProcessRuntime

public interface CorrelationAwareProcessRuntime
Classes that implement this interface will provide additional capabilities based on correlation. Most important to allow users to define custom correlation keys as an alternative to considered internal process instance id.

  • Method Details

    • startProcess

      ProcessInstance startProcess(String processId, CorrelationKey correlationKey, Map<String,Object> parameters)
      Start a new process instance. The process (definition) that should be used is referenced by the given process id. Parameters can be passed to the process instance (as name-value pairs), and these will be set as variables of the process instance.
      Parameters:
      processId - the id of the process that should be started
      correlationKey - custom correlation key that can be used to identify process instance
      parameters - the process variables that should be set when starting the process instance
      Returns:
      the ProcessInstance that represents the instance of the process that was started

    • createProcessInstance

      ProcessInstance createProcessInstance(String processId, CorrelationKey correlationKey, Map<String,Object> parameters)
      Creates a new process instance (but does not yet start it). The process (definition) that should be used is referenced by the given process id. Parameters can be passed to the process instance (as name-value pairs), and these will be set as variables of the process instance. You should only use this method if you need a reference to the process instance before actually starting it. Otherwise, use startProcess.
      Parameters:
      processId - the id of the process that should be started
      correlationKey - custom correlation key that can be used to identify process instance
      parameters - the process variables that should be set when creating the process instance
      Returns:
      the ProcessInstance that represents the instance of the process that was created (but not yet started)

    • startProcessFromNodeIds

      ProcessInstance startProcessFromNodeIds(String processId, CorrelationKey key, Map<String,Object> params, String... nodeIds)
      Starts a process with the values supplied from the current nodes
      Parameters:
      processId - The process's identifier
      correlationKey - correlation key to be assigned to process instance - must be unique
      params - process variables
      nodeIds - list of unique node ids that would be triggered once the process is created
      Returns:
      process instance identifier
      Throws:
      RuntimeException - in case of encountered errors
      DeploymentNotFoundException - in case deployment with given deployment id does not exist
      DeploymentNotActiveException - in case deployment with given deployment id is not active

    • getProcessInstance

      ProcessInstance getProcessInstance(CorrelationKey correlationKey)
      Returns the process instance with the given correlationKey. Note that only active process instances will be returned. If a process instance has been completed already, this method will return null.
      Parameters:
      correlationKey - the custom correlation key assigned when process instance was created
      Returns:
      the process instance with the given id or null if it cannot be found
