FBlueprintActionDatabase

Syntax

class FBlueprintActionDatabase :  
    public FGCObject,  
    public FTickableEditorObject

Remarks

Serves as a container for all available blueprint actions (no matter the type of blueprint/graph they belong in). The actions stored here are not tied to a specific ui menu; each action is a UBlueprintNodeSpawner which is charged with spawning a specific node type. Should be set up in a way where class specific actions are refreshed when the associated class is regenerated.

@TODO: Hook up to handle class recompile events, along with enum/struct asset creation events.
