running property
Running is true while THIS process is materialising the version. A version that is materializing and not running was started by a process that is gone — two states the register cannot tell apart, because a register cannot know which processes are alive.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
bool? running;
