Syntax

class FCacheRecord  

Remarks

A cache record is a key, an array of values, and metadata.

The key must uniquely correspond to its values. The key must never be reused for other values. The metadata does not have this requirement and may be used to persist details that vary, such as the time to generate the values or the machine that generated them.

Constructors

No constructors are accessible with public or protected access.
