+/**
+ * TODO: Support getting vnf type = vpe
+ *
+ * This class supports the GenericGetVnf Sub Flow.
+ * This Generic sub flow can be used by any flow for accomplishing
+ * the goal of getting a Vnf Object (from AAI).  The flow currently
+ * supports the querying of 2 types of Vnfs, generic-vnf and vce. The
+ * type must be provided by the calling flow and the type should
+ * be mapped to the variable GENDV_type. The type should either be
+ * "generic-vnf" or "vce".  If the Vnf Id is not provided by the calling
+ * flow then this sub flow will execute the query to get the
+ * Vnf using the Vnf Name. Therefore, the calling flow must provide
+ * either the Vnf Id or Vnf Name.
+ *
+ * Upon successful completion of this sub flow the
+ * GENDV_SuccessIndicator will be true and the query response payload
+ * will be set to GENDV_vnf.  An MSOWorkflowException will
+ * be thrown upon unsuccessful completion or if an error occurs
+ * at any time during this sub flow. Please map variables
+ * to the corresponding variable names below.
+ *
+ * Note - if this sub flow receives a Not Found (404) response
+ * from AAI at any time this will be considered an acceptable
+ * successful response however the GENDV_FoundIndicator
+ * set to false.  This will allow the calling flow to distinguish
+ * between the two success scenarios, "Success where Vnf is found"
+ * and "Success where Vnf is NOT found".
+ *
+ *
+ * Incoming Variables:
+ * @param - GENDV_vnfId
+ * @param - GENDV_type
+ * @param (Optional) - GENDV_resourceVersion
+ *
+ *
+ * Outgoing Variables:
+ * @param - GENDV_vnf
+ * @param - GENDV_SuccessIndicator
+ * @param - GENDV_FoundIndicator
+ * @param - WorkflowException
