What Is It?​

The Property Expressions API gives programmers advanced functionality for controlling Job Dependencies and Events. Property expressions access system and user-defined properties to perform operations whose results drive decisions. For more information, refer to Property Expressions API Syntax.

Use cases covered in that reference section include:

  • A job dependency on the specific string value of a property
  • A job dependency on the specific numeric (integer) value of a property
  • A job dependency on a machine running no jobs
  • Triggering events based on deviation from estimated run time
  • Setting the value of a property with an expression

FAQs​

Q: What is the Property Expressions API used for?

The Property Expressions API gives programmers advanced functionality for controlling Job Dependencies and Events. Expressions can access system and user-defined properties to perform operations whose results drive scheduling decisions.

Q: Can a property expression be used as a job dependency condition?

Yes. Property expressions can evaluate string values, numeric (integer) values, or machine states as dependency conditions — enabling complex, data-driven dependency logic beyond standard job dependencies.

Q: Where can I find the full syntax for property expressions?

The complete syntax reference is available in Property Expressions API Syntax.

Glossary​

Machine: A platform defined in the OpCon database that has an agent installed. OpCon routes job execution requests to machines via SMANetCom, and machines report job completion status back to SAM.

Job: The fundamental unit of work in OpCon. A job defines what to run, on which machine, when to start, and what conditions must be met. Job results are tracked and can trigger events and notifications.
