| virtual void | Open (const wchar_t *pDevNames)=0 |
| Opens the data and prepares it for collection. This will be called once and before Collect() is ever called. | |
| virtual void | Close ()=0 |
| Closes the data and cleans up and resources. This will be called once after all calls to Collect() that will be made have been completed. | |
| virtual bool | CollectW (const wchar_t *pszValueName, BYTE **ppData, DWORD *pcbTotalBytes, DWORD *pNumObjectTypes)=0 |
| Collects data. See here for more details on how to interpret the parameters to this function. | |
