Syntax

virtual UEdGraphNode * Invoke
(
    UEdGraph * ParentGraph,
    FBindingSet const & Bindings,
    FVector2D const Location
) const

Remarks

Takes care of spawning a node for the specified graph. Looks to see if the supplied graph is transient, and if so, spawns a NOT fully formed node (intended for template use).

This function is intended to be overridden; sub-classes may return a pre-existing node, instead of a newly allocated one (for cases where only one instance of the node type can exist). Callers should check for this case upon use.

Returns

Null if it failed to spawn a node, otherwise a newly spawned node or possibly one that already existed.

Parameters

Parameter	Description
ParentGraph	The graph you want the node spawned into.
Bindings
Location	Where you want the new node positioned in the graph.
