Variant sink

Activates one output branch before execution; inactive branch consumers are omitted.

Implementation ID

Behavior

Only the selected output branch and its downstream consumers remain active in the compiled graph.

Interface

Variant sink interfaceInputs or arguments on the left, observed outputs on the right. Conserving terminals appear below the component. The tables give units and behavior.Variant sinkStudio blockin0out0out1

Equations and rules

  • selected output = input; inactive consumers are excluded from execution

Worked example

Variant sink — executable model

Input3 reaches the active gain2 and produces6. The inactive gain100 is absent from execution.

Limits and interpretation

  • Selection is fixed before execution. This does not emit zeros to inactive branches.

Reference basis

This compiler and software type contract is defined by the documented behavior and executable example; no external research result or full external API parity is claimed.
