JKI State Machine Objects (SMO) by JKI - Toolkit for LabVIEW Download

[Fix: 40] onProcessStart( ) has been moved to the process thread to be symmetrical with onProcessStop( ).
[Fix: 41] onStopped, onStarted and onProcessStopped methods must require overrides to call parent.
[Fix: 42] Process now resets call-parent state when process terminates, to prepare process for consistent restart conditions, if requested.
[Fix: 43] onProcessStopped now symmetrical with onProcessStart, in Process thread.
[Feature: 45] Create method now allows a dependency to be declared as shared without specific ownership.
[Fix: 46] dependencies are now stopped during the onStopped callback, not onStop.
[Fix: 47] LaunchDependency method, called during onStart, is split in two parts: one that creates the dependency and takes ownership on creation (in a non-reentrant method to disallow concurrent creations), the second to start the dependency which is reentrant to allow recursive calls.

[Fix: 36] Fixed an issue where Shared Dependencies that are aggregated in the Static Dependencies list would be filtered out.

[Feature: 35] Adding reserve mechanism to limit accessibility to public methods to a single master.
- Default behavior is unreserved for all methods.
- Developer is required to implement the Check Availability on a method-per-method basis to take advantage of this feature in critical systems.
- Technically allows a way to deny access to public API calls during critical states.

[Fix: 32] Parent process can now be overwritten by child implementation

[Feature: 31] Stop Dependency now exposes a timeout terminal (default = -1)

[Feature] List Dependencies method has been made protected (previously private) after addition of ownership verification which is meant to prevent leaking the dependencies list in composition hierarchy. This node is supposed to be used solely to access dependencies in own inheritance tree. An unauthorized call will return an empty list.

[Feature:30] Dependency can now self-terminate and dependent takes care of destroying reference.

[Feature] Added a protected method to allow dependency to message dependent (send any packet of information) which is handled by onDependencyMessage ( ) callback method.

[Feature: 28] Added support to stop dynamic dependencies at runtime.

[Feature: 24] Destroy should try to Stop SMO gracefully before Abort

[Feature: 25] Stop SMO Zombie Processes when Creator Call Chain Goes Idle

[Feature: 22] Modified the Process Sync methods to allow usign them into subVIs of the Process.vi dynamic dispatch. This allows to encapsulate a process loop into a subVI and change its reentrancy settings at will.

[Feature] SMO.Example process demonstrates how to launch JKI State Machine process VI as a standalone tester without call for parent node.

[Fix: 21] Stopping aggregated dependencies no longer can produce a 1556 error on termination when dependency has already been terminated.

[Feature] SMO Class banner and wire color modified to remove confusion with Event Registration refnum.

[Fix] Launching SMO Processes with a strictly typed VI definition caused LabVIEW to not release references after objects were destroyed (classes locked after proper stop of objects) ref: https://labviewcoder.com/2016/07/06/quick-tip-asynchronously-launching-vis-the-right-way

[Feature] Added onStarted and onStopped to activity diagram
[Fix] Race condition in multiple Start-Stop SMOs as shown by Unit Test failure

[Fix] Fixed process notifier reference leak on stopping SMO

[Fix] Closed the registry reference after unregistration of the last SMO

-Fixed an issue with SMO Base process that would hang if called without timeout

-Added SMO Name terminal on Create Public constructor
-Added UI State Public Event (Closed, Opened)

- Fixed an issue with stop process sequence on unhandled errors.

- Added handling of timeout on Stop method
- Added a Stop command on Unhandled Error.

- Adjusted reentrancy settings for SMO overridable methods
- Get PublicEvents is now a public method (this exposes the references to developer, which should not generate events outside of the process, but is convenient to avoid event structure linkage issues on renaming and rewiring)

- Refactored Sync process
- Added virtual onStart( ), onStop( ), onProcessStart( ), onProcessStop( ) methods for overrides.

- Removed template classes.

- Modified the process synchronization method to use Notifiers instead of resizable Randezvous.
- Modified the SMO.UI.Template to include template event.

- Simplified the SMO.UI.Template so that it is more basic and reusable.
- Updated SMO launcher icons.

Updated the palette to include protected methods of the SMO and SMO.UI classes.
