Syntax
class UBlueprintVariableNodeSpawner : public UBlueprintFieldNodeSpawner
Remarks
Takes care of spawning variable getter/setter nodes. Serves as the "action" portion for certain FBlueprintActionMenuItems. Evolved from FEdGraphSchemaAction_K2Var, and can spawn nodes for both member-variables and local function variables.

Functions
| Type | Name | Description | |
|---|---|---|---|
  |
UBlueprintVariableNodeSpawner * | CreateFromLocal
(
TSubclassOf< UK2Node_Variable > NodeClass, |
Creates a new UBlueprintVariableNodeSpawner, charged with spawning a local-variable node (for a variable that belongs to a specific graph). |
  |
UBlueprintVariableNodeSpawner * | CreateFromMemberOrParam
(
TSubclassOf< UK2Node_Variable > NodeClass, |
Creates a new UBlueprintVariableNodeSpawner, charged with spawning a member-variable node (for a variable that has an associated FProperty) |
  |
FFieldVariant | GetVarOuter () |
If this is a local variable, then this will return the UEdGraph that it belongs to, otherwise it pulls the outer from the wrapped member-variable property. |
  |
FProperty const * | Accessor to the variable's property. | |
  |
FEdGraphPinType | GetVarType () |
Utility function for easily accessing the variable's type (needs to pull the information differently if it is a local variable as opposed to a member variable with a FProperty). |
  |
bool | Since this spawner can wrap both local and member variables, we use this method to discern between the two. | |
  |
bool |
Overridden from UBlueprintNodeSpawner

   |
FBlueprintNodeSignature | We want to be able to compare spawners, and have a signature that is rebuildable on subsequent runs. | |
   |
FBlueprintActionUiSpec | GetUiSpec
(
FBlueprintActionContext const& Context, |
Takes the default FBlueprintActionUiSpec and modifies it dynamically to accommodate the current context. |
   |
UEdGraphNode * | Invoke
(
UEdGraph* ParentGraph, |
Takes care of spawning a node for the specified graph. |
  |
void | Prime () |
Not required, but intended to passively help speed up menu building operations. |
