Detailed Description

The abstract class for subworkflow array steps.

A subworkflow step binds a child workflow (called a subworkflow) to a step and should be used to implement support for complex logical branching in Qorus.

Subworkflow steps may not have validation logic.

Example

# name: MySubworkflowArrayStep
# version: 1.0
# desc: my subworkflow array step class

class MySubworkflowArrayStep inherits QorusSubworkflowArrayStep {
    softlist<auto> array() {
        # .. array logic
    }

    primary(auto array_arg) {
        # ... primary step logic; must call one of:
        # * wf_bind_subworkflow()
        # * wf_skip_subworkflow()
    }
}
# END

Note

Qorus step constructors do not take any arguments; see Class-Based Step Constructors and Static Initialization for information about constructors and static class initialization.

Member Function Documentation

array()

abstract softlist<auto> OMQ::UserApi::Workflow::QorusSubworkflowArrayStep::array ( )

pure virtual

The array method returns the list of elements for the step.

Returns

The return value of the array function will determine how many times the step will execute, and on what data; null or a zero-length array means to skip the step entirely. Each element in this array indicates an array step element; each element will be passed as the argument to primary() and validation()

Note

this method must always return the same list in the same order in every call (for example if the step must be recovereed); use Workflow Dynamic Order Data to save the list to ensure that this method always returns the same list in the same order if necessary

primary()

abstract nothing OMQ::UserApi::Workflow::QorusSubworkflowArrayStep::primary ( auto  array_arg )

pure virtual

The primary step logic for the subworkflow step.

Parameters

array_arg

the array element for this step index as returned by the array method

This code must call either wf_bind_subworkflow() or wf_skip_subworkflow() or an error will be raised.

If the step is not to be skipped, then the step nust bind a subworkflow order to the step by calling the wf_bind_subworkflow() workflow API function.
