Windows

Linux

References

Module	CoreUObject
Header	/Engine/Source/Runtime/CoreUObject/Public/UObject/SparseDelegate.h
Include	#include "UObject/SparseDelegate.h"

Syntax

void __Internal_AddUnique
(
    const UObject * DelegateOwner,
    FName DelegateName,
    FScriptDelegate InDelegate
)

Remarks

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

NOTE: Only call this function from blueprint sparse delegate infrastructure on a resolved generic FScriptDelegate pointer. Generally from C++ you should call AddUnique() directly.

Parameters

Parameter	Description
DelegateOwner	UObject that owns the resolved sparse delegate
DelegateName	Name of the resolved sparse delegate
InDelegate	Delegate to bind to the sparse delegate
