Variables

  Type Name Description  
Public variable int32 EventGraphCallOffset The state offset inside of the event graph (persistent)  
Public variable UFunction * EventGraphFunction The event graph this function calls in to (persistent)  
Public variable FProperty * FirstPropertyToInit Pointer to first local struct property in this UFunction that contains defaults  
Public variable EFunctionFlags FunctionFlags EFunctionFlags set defined for this function  
Public variable uint8 NumParms Number of parameters total  
Public variable uint16 ParmsSize Total size of parameters in memory  
Public variable uint16 ReturnValueOffset Memory offset of return value property

Functions

  Type Name Description
Public function Static void  
Public function Static UObject *  
Public function Static uint64 Returns the flags that are ignored by default when comparing function signatures.
Public function Const FNativeFuncPtr Returns the native func pointer.
Public function Const UClass *  
Public function Const UClass * Returns the owning UClass* without branching
Public function Const FProperty * Returns the return value property if there is one, or null
Public function Const UFunction * Returns parent function if there is one, or null
Public function Const bool

HasAllFunctionFlags ( EFunctionFlags FlagsToCheck
)

 Used to safely check whether all of the passed in flags are set.
Public function Const bool

HasAnyFunctionFlags ( EFunctionFlags FlagsToCheck
)

 Used to safely check whether the passed in flag is set.
Public function void Initializes transient members like return value offset
Public function void

Invoke ( UObject* Obj,
FFrame& Stack,
void*const Z_Param__Result
)

 Invokes the UFunction on a UObject.
Public function Const bool

IsSignatureCompatibleWith ( const UFunction* OtherFunction,
uint64 IgnoreFlags
)

 Determines if two functions have an identical signature (note: currently doesn't allow matches with class parameters that differ only in how derived they are; there is no directionality to the call)
Public function Const bool

IsSignatureCompatibleWith ( const UFunction* OtherFunction
)

 Determines if two functions have an identical signature (note: currently doesn't allow matches with class parameters that differ only in how derived they are; there is no directionality to the call)
Public function void

SetNativeFunc ( FNativeFuncPtr InFunc
)

 Sets the native func pointer.
Public function Static UClass * Returns a UClass object representing this class at runtime
Public function Static EClassCastFlags Returns the static cast flags for this class
Public function Static const TCHAR * Returns the package this class belongs in
Public function Static void  

Overridden from UStruct

  Type Name Description
Public function Virtual Const UStruct * Returns the structure used for inheritance, may be changed by child types
Public function Virtual void

Link ( FArchive& Ar,
bool bRelinkExistingProperties
)

 Creates the field/property links and gets structure ready for use at runtime

Overridden from UField

  Type Name Description
Public function Virtual void

Bind ()

  

Overridden from UObject

  Type Name Description
Public function Virtual void Do any object-specific cleanup required immediately after loading an object.
Public function Virtual void Handles reading, writing, and reference collecting using FArchive.

Operators

  Type Name Description
Public function void

operator delete ( void* InMem
)

Public function void *

operator new ( const size_t InSize,
EInternal* InMem
)

 For internal use only; use StaticConstructObject() to create new objects.
Public function 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.
