Class Domain

java.lang.Object
io.trino.spi.predicate.Domain
public final class Domain extends Object
Defines the possible values of a single variable in terms of its valid scalar values and nullability.

For example:

  • Domain.none() => no scalar values allowed, NULL not allowed
  • Domain.all() => all scalar values allowed, NULL allowed
  • Domain.onlyNull() => no scalar values allowed, NULL allowed
  • Domain.notNull() => all scalar values allowed, NULL not allowed
