TScriptMapWrapper | Unreal Engine 5.8 Documentation

API > API/Plugins > API/Plugins/PCG

Class meant to wrap around a FScriptMapHelper, to manipulate it like a TMap and have type checking. It is not meant to be initialized by the user, but by the generic attributes (hence why only the default ctor is exposed). Since it contains a FScriptMapHelper, which contains a FScriptMap pointer, lifetime is not guaranteed. Can convert to a TMap, but this operation will do a full copy, so it might be expensive. Note that it is also read-only, so support only const operations.
