Syntax

class UK2Node_ConstructObjectFromClass : public UK2Node

Variables

  Type Name Description
Protected variable FNodeTextCache CachedNodeTitle Constructing FText strings can be costly, so we cache the node's title
Protected variable FText NodeTooltip Tooltip text for this node.

Constructors

  Type Name Description
Public function    

Functions

  Type Name Description
Public function Virtual void

CreatePinsForClass ( UClass* InClass,
TArray< UEdGraphPin* >* OutClassPins
)

 Create new pins to show properties on archetype
Protected function Virtual Const FText Gets the node for use in lists and menus
Public function Const UEdGraphPin *

GetClassPin ( const TArray< UEdGraphPin* >* InPinsToSearch
)

 Get the blueprint input pin
Protected function Virtual Const UClass * Gets base class to use for the 'class' pin.
Public function Const UClass *

GetClassToSpawn ( const TArray< UEdGraphPin* >* InPinsToSearch
)

 Get the class that we are going to spawn, if it's defined as default value
Protected function Virtual Const FText Gets the default node title when no class is selected
Protected function Virtual Const FText Gets the node title when a class has been selected.
Public function Const UEdGraphPin * Get the result input pin
Public function Const UEdGraphPin * Get the result output pin
Public function Const UEdGraphPin * Get the then output pin
Public function Const UEdGraphPin * Get the world context input pin, can return NULL
Public function Virtual Const bool

IsCompatibleWithGraph ( const UEdGraph* TargetGraph
)

  
Public function Virtual Const bool See if this is a spawn variable pin, or a 'default' pin
Protected function void Refresh pins when class was changed
Protected function Const void

SetPinToolTip ( UEdGraphPin& MutatablePin,
const FText& PinDescription
)

 Takes the specified "MutatablePin" and sets its 'PinToolTip' field (according to the specified description)
Public function Virtual Const bool Returns if the node uses Outer input
Public function Virtual Const bool Returns if the node uses World Object Context input

Overridden from UK2Node

  Type Name Description
Public function Virtual Const ERedirectType

DoPinsMatchForReconstruction ( const UEdGraphPin* NewPin,
int32 NewPinIndex,
const UEdGraphPin* OldPin,
int32 OldPinIndex
)

 Whether or not two pins match for purposes of reconnection after reconstruction.
Public function Virtual Const void Replacement for GetMenuEntries().
Public function Virtual Const FText Override to provide a default category for specific node types to be listed under.
Public function Virtual Const void

GetNodeAttributes ( TArray< TKeyValuePair< FString, FString >>& OutNodeAttributes
)

 This function returns an arbitrary number of attributes that describe this node for analytics events
Public function Virtual Const bool Query if this is a node that is safe to ignore (e.g., a comment node or other non-structural annotation that can be pruned with no warnings).
Public function Virtual void Reallocate pins during reconstruction; by default ignores the old pins and calls AllocateDefaultPins() If you override this to create additional pins you likely need to call RestoreSplitPins to restore any pins that have been split (e.g. a vector pin split into its components)

Overridden from UEdGraphNode

  Type Name Description
Public function Virtual Const void

AddSearchMetaDataInfo ( TArray< struct FSearchTagDataPair >& OutTaggedMetaData
)

 Add's node data to the search metadata, override to collect more data that may be desirable to search for
Public function Virtual void Allocate default pins for a given node, based only the NodeType, which should already be filled in.
Public function Virtual Const FText Returns the keywords that should be used when searching for this node
Public function Virtual Const FText Gets the name of this node, shown in title bar
Public function Virtual Const void

GetPinHoverText ( const UEdGraphPin& Pin,
FString& HoverTextOut
)

 Fetch the hover text for a pin when the graph is being edited.
Public function Virtual FString

GetPinMetaData ( FName InPinName,
FName InKey
)

 Return the requested metadata for the pin if there is any
Public function Virtual Const FText Gets the tooltip to display when over the node
Public function Virtual Const bool

HasExternalDependencies ( TArray< class UStruct* >* OptionalOutput
)

 Returns whether or not this node has dependencies on an external structure If OptionalOutput isn't null, it should be filled with the known dependencies objects (Classes, Structures, Functions, etc).
Public function Virtual void Called when the connection list of one of the pins of this node is changed in the editor
Public function Virtual void Called when the DefaultValue of one of the pins of this node is changed in the editor
Public function Virtual void A chance to initialize a new node; called just once when a new node is created, before AutowireNewNode or AllocateDefaultPins is called.
