Sends the whole timeline down one of two paths depending on whether it has any values. Exactly one path runs, once. Switch decides per dated property; Branch decides once for the entire input. Reach for it when the behaviour of a whole mapping should change based on whether the upstream produced anything at all.

​
Outputs

  • Empty — taken when the input has no values. Wire the subgraph that should produce a value from somewhere else (a Constant, another Attribute, …). Leave it unwired to emit an empty timeline.
  • Not empty — taken otherwise, and receives the input unchanged. Leave it unwired to pass the input straight to the result.
  • Result — whatever the taken branch produced. Optional: without it, the branch’s own End finishes the mapping.
Each branch you wire needs its own End node at the far side, the same way Switch’s branches do.

​
Configuration

  • Counts as empty — No entries at all (the strict reading), No values which also counts a timeline made up entirely of gaps (entries whose value was cleared), or No value today which looks only at the segment effective right now and ignores the history behind it.
