Syntax

class UK2Node_ConstructObjectFromClass : public UK2Node

Variables

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

Constructors

	Name	Description
	UK2Node_ConstructObjectFromClass ( const FObjectInitializer& ObjectIn... )

Functions

	Name	Description
void	CreatePinsForClass ( UClass* InClass, TArray< UEdGraphPin* >* O... )	Create new pins to show properties on archetype
FText	GetBaseNodeTitle()	Gets the default node title when no class is selected
UEdGraphPin ...	GetClassPin ( const TArray< UEdGraphPin* >&... )	Get the blueprint input pin
UClass *	GetClassPinBaseClass()	Gets base class to use for the 'class' pin.
UClass *	GetClassToSpawn ( const TArray< UEdGraphPin* >&... )	Get the class that we are going to spawn, if it's defined as default value
FText	GetNodeTitleFormat()	Gets the node title when a class has been selected.
UEdGraphPin ...	GetOuterPin()	Get the result input pin
UEdGraphPin ...	GetResultPin()	Get the result output pin
UEdGraphPin ...	GetThenPin()	Get the then output pin
UEdGraphPin ...	GetWorldContextPin()	Get the world context input pin, can return NULL
bool	IsCompatibleWithGraph ( const UEdGraph* TargetGraph )
bool	IsSpawnVarPin ( UEdGraphPin* Pin )	See if this is a spawn variable pin, or a 'default' pin
void	OnClassPinChanged()	Refresh pins when class was changed
void	SetPinToolTip ( UEdGraphPin& MutatablePin, const FText& PinDescription )	Takes the specified "MutatablePin" and sets its 'PinToolTip' field (according to the specified description)
bool	UseOuter()	Returns if the node uses Outer input
bool	UseWorldContext()	Returns if the node uses World Object Context input

Overridden from UK2Node

	Name	Description
void	GetMenuActions ( FBlueprintActionDatabaseRegistrar&... )	Replacement for GetMenuEntries().
FText	GetMenuCategory()	Override to provide a default category for specific node types to be listed under.
void	GetNodeAttributes ( TArray< TKeyValuePair< FString, FSt... )	This function returns an arbitrary number of attributes that describe this node for analytics events
bool	HasExternalDependencies ( TArray< class UStruct* >*... )	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).
bool	IsNodeSafeToIgnore()	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).
void	ReallocatePinsDuringReconstruction ( TArray< UEdGraphPin* >& OldPi... )	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

	Name	Description
void	AddSearchMetaDataInfo ( TArray< struct FSearchTagDataPair >... )	Add's node data to the search metadata, override to collect more data that may be desirable to search for
void	AllocateDefaultPins()	Allocate default pins for a given node, based only the NodeType, which should already be filled in.
FText	GetKeywords()	Returns the keywords that should be used when searching for this node
FText	GetNodeTitle ( ENodeTitleType::Type TitleType )	Gets the name of this node, shown in title bar
void	GetPinHoverText ( const UEdGraphPin& Pin, FString& HoverTextOut )	Fetch the hover text for a pin when the graph is being edited.
FText	GetTooltipText()	Gets the tooltip to display when over the node
void	PinConnectionListChanged ( UEdGraphPin* Pin )	Called when the connection list of one of the pins of this node is changed in the editor
void	PinDefaultValueChanged ( UEdGraphPin* Pin )	Called when the DefaultValue of one of the pins of this node is changed in the editor
void	PostPlacedNewNode()	A chance to initialize a new node; called just once when a new node is created, before AutowireNewNode or AllocateDefaultPins is called.
