Constructor & Destructor Documentation

FSubsystemCollection()

template<typename TBaseType >

FSubsystemCollection< TBaseType >::FSubsystemCollection ( )

inline

Construct a FSubsystemCollection, pass in the owning object almost certainly (this).

Member Function Documentation

AddReferencedObjects()

template<typename TBaseType >

virtual void FSubsystemCollection< TBaseType >::AddReferencedObjects ( FReferenceCollector &  Collector )

inlineoverridevirtual

Pure virtual that must be overloaded by the inheriting class. Use this method to serialize any UObjects contained that you wish to keep around.

Parameters

Collector

The collector of referenced objects.

Implements FGCObject.

ForEachSubsystem()

template<typename TBaseType >

void FSubsystemCollection< TBaseType >::ForEachSubsystem ( TFunctionRef< void(TBaseType *)>  Operation, const TSubclassOf< TBaseType > &  SubsystemClass = {}  ) const

inline

Perform an operation on all subsystems of a given type in the collection

GetReferencerName()

template<typename TBaseType >

virtual FString FSubsystemCollection< TBaseType >::GetReferencerName ( ) const

inlineoverridevirtual

Overload this method to report a name for your referencer

Implements FGCObject.

GetSubsystem()

template<typename TBaseType >

template<typename TSubsystemClass >

TSubsystemClass * FSubsystemCollection< TBaseType >::GetSubsystem ( const TSubclassOf< TSubsystemClass > &  SubsystemClass ) const

inline

Get a Subsystem by type

GetSubsystemArrayCopy()

template<typename TBaseType >

template<typename TSubsystemClass >

TArray< TSubsystemClass * > FSubsystemCollection< TBaseType >::GetSubsystemArrayCopy ( const TSubclassOf< TSubsystemClass > &  SubsystemClass ) const

inline

Get a list of Subsystems by type
