Syntax

class FRepChangedHistory

Remarks

Represents a single changelist, tracking changed properties.

Properties are tracked via Relative Property Command Handles. Valid handles are 1-based, and 0 is reserved as a terminator.

Arrays are tracked as a special case inline, where the first entry is the number of array elements, followed by handles for each array element, and ending with their own 0 terminator.

Arrays may be nested by continually applying that pattern.
