Values

Name	Description
None	No copying.
Plain	For plain old data types, we do a simple memcpy.
Complex	For more complex data types, we need to call the properties copy function.
Bool	Read and write properties using bool property helpers, as source/dest could be bitfield or boolean.
Struct	Use struct copy operation, as this needs to correctly handle CPP struct ops.
Object	Read and write properties using object property helpers, as source/dest could be regular/weak/soft etc.
Name	FName needs special case because its size changes between editor/compiler and runtime.
Array	Array needs special handling for fixed size arrays.
PromoteBoolToByte	Promote the type during the copy Bool promotions
PromoteBoolToInt32
PromoteBoolToInt64
PromoteBoolToFloat
PromoteByteToInt32	Byte promotions.
PromoteByteToInt64
PromoteByteToFloat
PromoteInt32ToInt64	Int32 promotions.
PromoteInt32ToFloat
