project BLF > class Cacher > method GetValuesFromSession
Description
This method can be used to retrieve the values of more than one session dependent cached data items with one call. It avoids that the caller needs to do multiple "Get<datatype>Value" calls.
Parameters
| iiSessionId | input | integer | The unique ID of the session for which data item values need to be returend. |
| icNameList | input | character | A comma separated list of names of data items for which the values need to be returned. |
| ocValueList | output | character | A chr(2) separated list of values that correspond with the list of data items that is passed in icNameList. |
| oiReturnStatus | output | integer | Return status of the method. |
