Interface NumExpr

Javadoc 27 generates this reference during each site build from the exported packages and the annotation processor. The Java guide shows the API in use.

All Superinterfaces:

Domain<NumExpr>, Expr, NumericExpr

All Known Implementing Classes:

NumField

public sealed interface NumExpr extends NumericExpr, Domain<NumExpr> permits NumField<V> (not exhaustive)

A num expression: an integer or a float, decided by the data.

As a Domain, it gives a comprehension its elements, which are numbers too.
