Package io.automatiko.engine.services.correlation

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 Detail

      • startProcess

        io.automatiko.engine.api.runtime.process.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

        io.automatiko.engine.api.runtime.process.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)

      • getProcessInstance

        io.automatiko.engine.api.runtime.process.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
