struct FConstStructView

Remarks

FConstStructView is "typed" struct pointer, it contains const pointer to struct plus UScriptStruct pointer. FConstStructView does not own the memory and will not free it when of scope. It should be only used to pass struct pointer in a limited scope, or when the user controls the lifetime of the struct being stored. E.g. instead of passing ref or pointer to a FInstancedStruct, you should use FConstStructView or FStructView to pass around a view to the contents. FConstStructView is passed by value. FConstStructView is similar to FStructOnScope, but FConstStructView is a view only (FStructOnScope can either own the memory or be a view) FConstStructView prevents mutation of the actual struct data however the struct being pointed at can be changed to point at a different instance of a struct. To also prevent this use const FConstStructView. e.g. FStructView A; FConstStructView B = A; // compiles e.g. FStructView A; FConstStructView B; B = A; // compiles as B can be made to point at any other StructView e.g. FConstStructView A; FStructView B = A; // doesn't compile as the struct data for A is immutable (but mutable for B) e.g. FStructView A; A.Foo = NewVal; // compiles as the struct data for A is mutable. e.g. FConstStructView A; A.Foo = NewVal; // doesn't compile as the struct data for A is immutable. e.g. FStructView A; const FStructView B; A = B; // compiles as the struct B is pointing to can't be made to point at something else but A isn't const. e.g. const FStructView A; FStructView B; A = B; // doesn't compile as attempting to make const view point at something else
