Detailed Description

template<typename AssignedType>
struct TGuardValueAccessors< AssignedType >

Guard around saving/restoring a value. Commonly used to make sure a value is restored even if the code early outs in the future. Usage: TGuardValueAccessors GuardSomeBool(UE::SomeGetterFunction, UE::SomeSetterFunction, false); // Saves the state, sets the value, and restores it in dtor.
