Functions

Type	Name	Description
void	Add ( const TScriptDelegate< OtherThreadSafetyMode >& InDelegate )
void	Add ( const TScriptDelegate< ThreadSafetyMode >& InDelegate )	Adds a function delegate to this multi-cast delegate's invocation list
void	AddInternal ( UnicastDelegateType&& InDelegate )	Adds a function delegate to this multi-cast delegate's invocation list
void	AddUnique ( const TScriptDelegate< OtherThreadSafetyMode >& InDelegate )
void	AddUnique ( const TScriptDelegate< ThreadSafetyMode >& InDelegate )	Adds a function delegate to this multi-cast delegate's invocation list if a delegate with the same signature doesn't already exist in the invocation list
void	AddUniqueInternal ( UnicastDelegateType&& InDelegate )	Adds a function delegate to this multi-cast delegate's invocation list, if a delegate with that signature doesn't already exist
void	Clear ()	Removes all functions from this delegate's invocation list
void	CompactInvocationList ()	Cleans up any delegates in our invocation list that have expired (performance is O(N))
bool	Contains ( const TScriptDelegate< ThreadSafetyMode >& InDelegate )	Checks whether a function delegate is already a member of this multi-cast delegate's invocation list
bool	Contains ( const UObject* InObject, FName InFunctionName )	Checks whether a function delegate is already a member of this multi-cast delegate's invocation list
bool	Contains ( const TScriptDelegate< OtherThreadSafetyMode >& InDelegate )
TArray< typename UnicastDelegateType::WeakPtrType * >	GetAllObjectRefsEvenIfUnreachable ()
TArray< UObject * >	GetAllObjects ()	Returns all objects associated with this multicast-delegate.
TArray< UObject * >	GetAllObjectsEvenIfUnreachable ()	Returns all objects associated with this multicast-delegate, even if unreachable.
SIZE_T	GetAllocatedSize ()	Returns the amount of memory allocated by this delegate's invocation list, not including sizeof(*this).
bool	IsBound ()	Checks to see if any functions are bound to this multi-cast delegate
void	ProcessMulticastDelegate ( void* Parameters )	Executes a multi-cast delegate by calling all functions on objects bound to the delegate.
void	Remove ( const TScriptDelegate< ThreadSafetyMode >& InDelegate )	Removes a function from this multi-cast delegate's invocation list (performance is O(N)).
void	Remove ( const TScriptDelegate< OtherThreadSafetyMode >& InDelegate )
void	Remove ( const UObject* InObject, FName InFunctionName )	Removes a function from this multi-cast delegate's invocation list (performance is O(N)).
void	RemoveAll ( const UObject* Object )	Removes all delegate bindings from this multicast delegate's invocation list that are bound to the specified object.
void	RemoveInternal ( const UnicastDelegateType& InDelegate )	Removes a function from this multi-cast delegate's invocation list (performance is O(N)).
void	RemoveInternal ( const UObject* InObject, FName InFunctionName )	Removes a function from this multi-cast delegate's invocation list (performance is O(N)).
FString	ToString ()	Converts this delegate to a string representation
