Interface ExportOptions.CellTransform

Enclosing class:
ExportOptions
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface public static interface ExportOptions.CellTransform
A per-cell export decision computed by the app. Returned from ExportOptions.cellTransform(CellTransform); the engine applies it to that one cell, overriding the global ExportOptions.FormulaPolicy.

The callback MUST NOT mutate the cell or the book — it only inspects the cell and returns the desired action, so the source book is never altered by exporting.
