TCopyOnWriteArray | Unreal Engine 5.7 Documentation

API > API/Plugins > API/Plugins/ChaosRigidAssetNodes

Wrapper for an array that implements copy-on-write for the array. If there are N readers but no writers there will be a single copy of the array If a codepath writes to the array and they aren't the only referencer, the array will be duplicated This means each modification will not implicitly duplicate - only if there are multiple referencers otherwise, we modify in place.
