Variables

  Type Name Description
Public variable bool bEnforceConstCorrectness Whether or not to enforce const-correctness for const function overrides
Protected variable bool bUpdatedDefaultValuesOnLoad True if we've updated the default values on this node at least once
Public variable FName CustomGeneratedFunctionName If specified, the function that is created for this entry point will have this name.
Protected variable int32 ExtraFlags Any extra flags that the function may need
Protected variable TSharedPtr< FStructOnScope > FunctionVariableCache Holds a an in-memory representation of the UFunction struct, used to fixup local and user variables
Public variable TArray< FBPVariableDescription > LocalVariables Array of local variables to be added to generated function
Public variable FKismetUserDeclaredFunctionMetadata MetaData Function metadata

Functions

  Type Name Description
Public function void

AddExtraFlags ( int32 InFlags
)

  
Public function void

ClearExtraFlags ( int32 InFlags
)

  
Public function Const UEdGraphPin * Returns pin for the automatically added WorldContext parameter (used only by BlueprintFunctionLibrary).
Public function Const int32 Retrieves the extra flags set on this node.
Public function Const int32 Retrieves the function flags from the UFunction that this function entry node represents
Public function TSharedPtr< FStructOnScope >

GetFunctionVariableCache ( bool bForceRefresh
)

 Gets the UFunction and function variable cache structure that should be used for serialization fixups for local variables.
Public function Const bool

HasAllExtraFlags ( int32 FlagsToCheck
)

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

HasAnyExtraFlags ( int32 FlagsToCheck
)

 Used to safely check whether the passed in flag is set.
Public function Virtual Const bool

IsCompatibleWithGraph ( const UEdGraph* InGraph
)

  
Public function bool Copies data from the local variable defaults into the variable cache
Public function void

RemoveOutputPin ( UEdGraphPin* PinToRemove
)

 Removes an output pin from the node.
Public function void

SetExtraFlags ( int32 InFlags
)

 Set the extra flags on this node
Protected function bool

UpdateDefaultsFromVariableStruct ( const UStruct* VariableStruct,
uint8* VariableStructData
)

 Copies data from VariableStruct into the local variables
Public function bool

UpdateLoadedDefaultValues ( bool bForceRefresh
)

 Handles updating loaded default values, by going default string into variable cache and back, if bForceRefresh it will happen even if the cache is already setup
Protected function bool

UpdateVariableStructFromDefaults ( const UStruct* VariableStruct,
uint8* VariableStructData
)

 Copies data from any local variables matching properties in VariableStruct into the VariableStructData

Public function Virtual bool

CanCreateUserDefinedPin ( const FEdGraphPinType& InPinType,
EEdGraphPinDirection InDesiredDirection,
FText& OutErrorMessage
)

 Queries if a user defined pin of the passed type can be constructed on this node.
Public function Virtual Const bool Can this node have pass-by-reference parameters?
Public function Virtual UEdGraphPin * Creates a new pin on the node from the specified user pin info.
Public function Virtual bool

ModifyUserDefinedPinDefaultValue ( TSharedPtr< FUserPinInfo > PinInfo,
const FString& NewDefaultValue
)

 Modifies the default value of an existing pin on the node, this will update both the UserPinInfo and the linked editor pin
Public function Virtual Const bool Should this node require 'const' for pass-by-reference parameters?

Public function Virtual Const void

GetRedirectPinNames ( const UEdGraphPin& Pin,
TArray< FString >& RedirectPinNames
)

 Determines what the possible redirect pin names are
