The Event Manager calls the Generate function when an application raises the event without providing the event data and any subscriptions to the event require the event data. The Generate function returns the event data in clob format.
Note: If the event data is required but no Generate function is defined for the event, Oracle Workflow creates a default set of event data using the event name and event key.
The PL/SQL function that generates the event data must have the following standard API:
function <function_name> (p_event_name in varchar2,
p_event_key in varchar2
p_parameter_list in wf_parameter_list_t
default null)
return clob;
The arguments for the function are as follows:
p_event_name | The internal name of the event. |
p_event_key | A string generated when the event occurs within a program or application. The event key uniquely identifies a specific instance of the event. |
p_parameter_list | An optional list of additional parameter name and value pairs for the event. |
