class FCacheRecordPolicy
Remarks
Flags to control the behavior of cache record requests, with optional overrides by value.
Examples:
- A base policy of None with value policy overrides of Default will fetch those values if they exist in the record, and skip data for any other values.
- A base policy of Default, with value policy overrides of (Query | SkipData), will skip those values, but still check if they exist, and will load any other values.
