Examples of com.facebook.presto.spi.Domain

com.facebook.presto.spi.Domain
Defines the possible values of a single variable in terms of its valid scalar ranges 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
