16 | * The basic functionality of this processor is that variables from the $params object are transformed | |
17 | * into xml. The xml is submitted to the processor's https site | |
18 | * using curl and the response is translated back into an array using the processor's function. | |
19 | * | |
20 | * If an array ($params) is returned to the calling function the values from | |
21 | * the array are merged into the calling functions array. | |
22 | * | |
23 | * If an result of class error is returned it is treated as a failure. No error denotes a success. Be | |
24 | * WARY of this when coding | |
