FunctionFlags :

Name	Feature	Value	Description	UFUNCTION/UDELEGATE	UFUNCTION/UDELEGATE 1	USTRUCT
FUNC_Final	Trait	0x00000001	Function is final (prebindable, non-overridable function).	SealedEvent
FUNC_RequiredAPI	Dll	0x00000002	Indicates this function is DLL exported/imported.
FUNC_BlueprintAuthorityOnly	Network	0x00000004	Function will only run if the object has network authority	BlueprintAuthorityOnly
FUNC_BlueprintCosmetic	Network	0x00000008	Function is cosmetic in nature and should not be invoked on dedicated servers	BlueprintCosmetic
FUNC_Net	Network	0x00000040	Function is network-replicated.	Client, NetMulticast, Server, ServiceRequest, ServiceResponse
FUNC_NetReliable	Network	0x00000080	Function should be sent reliably on the network.	Reliable, ServiceRequest, ServiceResponse
FUNC_NetRequest	Network	0x00000100	Function is sent to a net service	ServiceRequest
FUNC_Exec	Trait	0x00000200	Executable from command line.	Exec
FUNC_Native	Trait	0x00000400	Native function.	BlueprintImplementableEvent
FUNC_Event	Trait	0x00000800	Event function.	BlueprintImplementableEvent, BlueprintNativeEvent, ServiceRequest, ServiceResponse
FUNC_NetResponse	Network	0x00001000	Function response from a net service	ServiceResponse
FUNC_Static		0x00002000	Static function.
FUNC_NetMulticast	Network	0x00004000	Function is networked multicast Server -> All Clients	NetMulticast
FUNC_UbergraphFunction	Blueprint	0x00008000	Function is used as the merge 'ubergraph' for a blueprint, only assigned when using the persistent 'ubergraph' frame
FUNC_MulticastDelegate	Trait	0x00010000	Function is a multi-cast delegate signature (also requires FUNC_Delegate to be set!)
FUNC_Public	Trait	0x00020000	Function is accessible in all classes (if overridden, parameters must remain unchanged).
FUNC_Private	Trait	0x00040000	Function is accessible only in the class it is defined in (cannot be overridden, but function name may be reused in subclasses. IOW: if overridden, parameters don't need to match, and Super.Func() cannot be accessed since it's private.)
FUNC_Protected	Trait	0x00080000	Function is accessible only in the class it is defined in and subclasses (if overridden, parameters much remain unchanged).
FUNC_Delegate	Trait	0x00100000	Function is delegate signature (either single-cast or multi-cast, depending on whether FUNC_MulticastDelegate is set.)
FUNC_NetServer	Network	0x00200000	Function is executed on servers (set by replication code if passes check)	Server
FUNC_HasOutParms	Trait	0x00400000	function has out (pass by reference) parameters
FUNC_HasDefaults	Trait	0x00800000	function has structs that contain defaults			HasDefaults
FUNC_NetClient	Network	0x01000000	function is executed on clients	Client
FUNC_DLLImport	Dll	0x02000000	function is imported from a DLL
FUNC_BlueprintCallable	Blueprint	0x04000000	function can be called from blueprint code	BlueprintGetter, BlueprintPure, BlueprintSetter, BlueprintCallable
FUNC_BlueprintEvent	Blueprint	0x08000000	function can be overridden/implemented from a blueprint	BlueprintImplementableEvent, BlueprintNativeEvent
FUNC_BlueprintPure	Blueprint	0x10000000	function can be called from blueprint code, and is also pure (produces no side effects). If you set this, you should set FUNC_BlueprintCallable as well.	BlueprintGetter, BlueprintPure
FUNC_EditorOnly	Trait	0x20000000	function can only be called from an editor scrippt.
FUNC_Const	Trait	0x40000000	function can be called from blueprint code, and only reads state (never writes state)
FUNC_NetValidate	Network	0x80000000	function must supply a _Validate implementation	WithValidation
