      • setState

        public Process setState(Record state)
        Current state of a process. As with Records in general, any field of a Record may contain a nested Record or Array of Records, so the process state is essentially a hierarchical data structure.

        Transient state

        In addition to the explicit process state there is a "transient state." The transient state represents the complete output of each of the last tasks of each type within the current process execution. This allows easy reference to the previous task output with taskInputExpressions.

        If this method is called after the component has been drawn/initialized: Set process state for current process
        Parameters:
        state - the new process state. Default value is null
        Returns:
        Process instance, for chaining setter calls
      • getState

        public Record getState()
        Current state of a process. As with Records in general, any field of a Record may contain a nested Record or Array of Records, so the process state is essentially a hierarchical data structure.

        Transient state

        In addition to the explicit process state there is a "transient state." The transient state represents the complete output of each of the last tasks of each type within the current process execution. This allows easy reference to the previous task output with taskInputExpressions.

      • setNextElement

        public void setNextElement(java.lang.String nextElement)
        Sets the task ID of the next task to execute after the current task finishes. If the task is not found or null is passed as the nextElement, the current process will be terminated instead.
