SO uses a REST-based +interface. However, as requests may not complete right away, a REST-based polling +interface is used to check the status of the request. The *requestId* is extracted +from the initial response and is appended to the *pathGet* configuration parameter to +generate the URL used to poll for completion. + +Each operation supported by the actor is associated with its own java class, which is +responsible for populating the request structure appropriately and sending the request. +Note: the request may be issued via POST, DELETE, etc., depending on the operation. +The operation-specific classes are all derived from the *SoOperation* class, which is, +itself, derived from *HttpOperation*. The following operations are currently supported: + +- VF Module Create +- VF Module Delete + + +Request +####### + +A number of nested structures are populated within the request. Several of them are +populated with data extracted from the A&AI Custom Query response that is retrieved +using the Target resource ID specified in the *ControlLoopOperationParams*. The +following table lists the contents of some of the fields that appear within these +structures. + ++----------------------------------+---------+----------------------------------------------------------------------+ +| Field Name | Type | Description | ++----------------------------------+---------+----------------------------------------------------------------------+ ++----------------------------------+---------+----------------------------------------------------------------------+ +| top level: | | | ++----------------------------------+---------+----------------------------------------------------------------------+ +| *operationType* | string | Inserted by Policy.
