Syntax
template<typename T, int NumInputs, int StorageTypeIdentifier>
class TSwitchNode : public UE::GeometryFlow::FNode
Remarks
TSwitchNode selects one of N inputs and provides it as an Output. This allows for a minimal amount of branching / control-flow in a fixed GeometryFlowGraph. Only the active Input is evaluated.
The number of inputs is defined in the template type, eg TSwitchNode
Use UpdateSwitchValue() to select the active switch Input
