Passing Arguments

JS7 - GraalVM Python Jobs are based on Oracle® GraalVM and can pass arguments to subsequent jobs and instructions in a workflow:

  • Consider that JS7 - Order Variables and variables declared with the workflow or JS7 - Job Resources are constants. They cannot be modified and they cannot be passed, they are available to any jobs.
  • Jobs can add variables and can modify variables added by predecessor jobs.

FEATURE AVAILABILITY STARTING FROM RELEASE 2.8.2

Example for implementation of JS7Job with GraalVM Python
class JS7Job(js7.Job):
    def processOrder(self, js7Step):
        # do some stuff to calculate return values
        someString = "some string"
        someNumber = 42
        someBoolean = True
       
        # pass return values to subsequent jobs
        js7Step.getOutcome().putVariable("some_var_string", someString)
        js7Step.getOutcome().putVariable("some_var_number", someNumber)
        js7Step.getOutcome().putVariable("some_var_boolean", someBoolean)


Explanation:

  • The getOutcome().putVariable() method specifies the name and value of the variable to be passed.
  • The name of the variable can be freely chosen within the scope of JS7 - Object Naming Rules.
  • Variable names are case-sensitive.
