Class Sequel::Postgres::InetOp
In: lib/sequel/extensions/pg_inet_ops.rb
Parent: Sequel::SQL::Wrapper

The InetOp class is a simple container for a single object that defines methods that yield Sequel expression objects representing PostgreSQL inet operators and functions.

Most methods in this class are defined via metaprogramming, see the pg_inet_ops extension documentation for details on the API.

Public Class methods

new(v)

For String and IPAddr instances, wrap them in a cast to inet, to avoid ambiguity issues when calling operator methods.
