Values
| Name |
Remarks |
| 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 |
|
| PromoteBoolToDouble |
|
| PromoteByteToInt32 |
Byte promotions. |
| PromoteByteToInt64 |
|
| PromoteByteToFloat |
|
| PromoteByteToDouble |
|
| PromoteInt32ToInt64 |
Int32 promotions. |
| PromoteInt32ToFloat |
|
| PromoteInt32ToDouble |
|
| PromoteFloatToDouble |
Float promotions // LWC_TODO: Float/double should become synonyms? |
