The job class APIs are documented here:
A job's job class must inherit one of:
This means that job code can call static methods defined in the base classes directly.
For library classes and other job code, calls must be prefixed with the class name (also for all Java code as well).
Each job has a single Qore Program object containing the code to be defined when the job trigger time arrives, as well as any objects imported into the Program object (classes, constants, and functions listed as attributes of the job when the job is defined). Job Program objects are restricted from using elements of the Qore language related to process and thread control; the use of these functions is either dangerous or could violate the integrity of the Qorus server process and therefore is restricted.
To enforce these restrictions, job Program objects are created with the following sandbox flags:
| Directive | Constant | Description |
| %allow-weak-references | Qore::PO_ALLOW_WEAK_REFERENCES | the := operator may be used |
| %no-process-control | Qore::PO_NO_PROCESS_CONTROL | Functionality that affects the entire process is unavailable |
| %no-thread-control | Qore::PO_NO_THREAD_CONTROL | Thread management functionality is unavailable |
| %no-top-level | Qore::PO_NO_TOP_LEVEL_STATEMENTS | No code is allowed in the top-level statement (outside a function or class) |
| %require-our | Qore::PO_REQUIRE_OUR | All variables must be declared before use |
Please note that despite these restrictions, job program objects have most of the Qore language API and class library available for use.
Furthermore, the following parse defines are defined:
