If isControlType=true for an ObjectNode, ControlFlows may be incoming to and outgoing from the ObjectNode, objects tokens can come into or go out of the ObjectNode along ControlFlows, and these tokens can flow along ControlFlows reached downstream ... isControl : Boolean [1..1] = false Indicates whether the Pin provides data to the Action or just controls how the Action executes. Related snippets (backlinks) A control Pin (with isControl=true) must have a control type (isControlType=true), so that they may be used with ControlFlows. Control Pins are ignored in the constraints that Actions place on Pins (including matching to parameters for InvocationActions ...). Tokens arriving at a control InputPin have the same semantics as control tokens arriving at the Action, except that control tokens can be buffered in control Pins. Tokens are placed on control OutputPins according to the same semantics as tokens placed on ControlFlows coming out of an Actions. Visit also Visit also (backlinks) Flags
