Variables

	Name	Description
int32	EventGraphCallOffset	The state offset inside of the event graph (persistent)
UFunction *	EventGraphFunction	The event graph this function calls in to (persistent)
FProperty *	FirstPropertyToInit	Pointer to first local struct property in this UFunction that contains defaults
EFunctionFlags	FunctionFlags	EFunctionFlags set defined for this function
uint8	NumParms	Number of parameters total
uint16	ParmsSize	Total size of parameters in memory
uint16	ReturnValueOffset	Memory offset of return value property
uint16	RPCId	Id of this RPC function call (must be FUNC_Net & (FUNC_NetService\|FUNC_NetResponse))
uint16	RPCResponseId	Id of the corresponding response call (must be FUNC_Net & FUNC_NetService)

Constructors

	Name	Description
	UFunction ( const FObjectInitializer& ObjectIn... )
	UFunction ( FVTableHelper& Helper )	DO NOT USE. This constructor is for internal usage only for hot-reload purposes.
	UFunction ( UFunction* InSuperFunction, EFunctionFlags InFunctionFlags, SIZE_T ParamsSize )
	UFunction ( const FObjectInitializer& ObjectIn..., UFunction* InSuperFunction, EFunctionFlags InFunctionFlags, SIZE_T ParamsSize )	Constructors.

Functions

	Name	Description
void	__DefaultConstructor ( const FObjectInitializer& X )
UObject *...	__VTableCtorCaller ( FVTableHelper& Helper )
uint64	GetDefaultIgnoredSignatureCompatibilityFlags()	Returns the flags that are ignored by default when comparing function signatures.
FNativeFuncP...	GetNativeFunc()	Returns the native func pointer.
UClass *	GetOuterUClass()
UClass *	GetOuterUClassUnchecked()	Returns the owning UClass* without branching
FProperty &#...	GetReturnProperty()	Returns the return value property if there is one, or null
UFunction &#...	GetSuperFunction()	Returns parent function if there is one, or null
bool	HasAllFunctionFlags ( EFunctionFlags FlagsToCheck )	Used to safely check whether all of the passed in flags are set.
bool	HasAnyFunctionFlags ( EFunctionFlags FlagsToCheck )	Used to safely check whether the passed in flag is set.
void	InitializeDerivedMembers()	Initializes transient members like return value offset
void	Invoke ( UObject* Obj, FFrame& Stack, void*const Z_Param__Result )	Invokes the UFunction on a UObject.
bool	IsSignatureCompatibleWith ( const UFunction* OtherFunction, uint64 IgnoreFlags )	Determines if two functions have an identical signature ( currently doesn't allow matches with class parameters that differ only in how derived they are; there is no directionality to the call)
bool	IsSignatureCompatibleWith ( const UFunction* OtherFunction )	Determines if two functions have an identical signature ( currently doesn't allow matches with class parameters that differ only in how derived they are; there is no directionality to the call)
void	SetNativeFunc ( FNativeFuncPtr InFunc )	Sets the native func pointer.
UClass *	StaticClass()	Returns a UClass object representing this class at runtime
EClassCastFl...	StaticClassCastFlags()	Returns the static cast flags for this class
const TCHAR ...	StaticPackage()	Returns the package this class belongs in
void	StaticRegisterNativesUFunction()

Overridden from UStruct

		Name	Description
	UStruct *...	GetInheritanceSuper()	Returns the structure used for inheritance, may be changed by child types
	void	Link ( FArchive& Ar, bool bRelinkExistingProperties )	Creates the field/property links and gets structure ready for use at runtime

Overridden from UField

		Name	Description
	void	Bind()

Overridden from UObject

		Name	Description
	void	PostLoad()	Do any object-specific cleanup required immediately after loading an object.
	void	Serialize ( FArchive& Ar )	Handles reading, writing, and reference collecting using FArchive.

Operators

		Name	Description
	void *	operator new ( const size_t InSize, EInternal* InMem )	For internal use only; use StaticConstructObject() to create new objects.
	void *	operator new ( const size_t InSize, EInternal InInternalOnly, UObject* InOuter, FName InName, EObjectFlags InSetFlags )	For internal use only; use StaticConstructObject() to create new objects.

Typedefs

Name	Description
Super	Typedef for the base class (UStruct)
ThisClass	Typedef for UFunction.
WithinClass	The required type of this object's outer (class UClass)

Constants

Name	Description
StaticClassFlags	Bitwise union of EClassFlags pertaining to this class.
