ParamDisplayValue Type

What the editor should display for one parameter of a sheet, computed from the value the parameter takes in every instance of the sheet under the top.

Union cases

Union case Description

NotUsed ParamInt

Full Usage: NotUsed ParamInt

Parameters:

Nothing under the top instantiates the sheet, so nothing gives the parameter a value. The stored value stands in until the sheet is used, and the properties pane shows it greyed and italic so that a provisional number is never read as a fact about the design.

Item : ParamInt

Values ParamInt list

Full Usage: Values ParamInt list

Parameters:

The values the instances give it: distinct, descending, never empty. The head is the one the sheet is drawn at. Several arise when one design reaches the sheet by paths that bind it differently, which is allowed; the largest is taken so that the choice is definite and the recomputation stays idempotent.
