@Immutable public class CqlIdentifier extends Object implements Serializable
It has two representations:

).
Create statement | Case-sensitive? | CQL id | Internal id |
---|---|---|---|
CREATE TABLE t(foo int PRIMARY KEY) | No | foo | foo |
CREATE TABLE t(Foo int PRIMARY KEY) | No | foo | foo |
CREATE TABLE t("Foo" int PRIMARY KEY) | Yes | "Foo" | Foo |
CREATE TABLE t("foo bar" int PRIMARY KEY) | Yes | "foo bar" | foo bar |
CREATE TABLE t("foo""bar" int PRIMARY KEY) | Yes | "foo""bar" | foo"bar |
CREATE TABLE t("create" int PRIMARY KEY) | Yes (reserved keyword) | "create" | create |

There is no internal caching; if you reuse the same identifiers often, consider caching them in your application.

- if true
, use the shortest possible representation: if the identifier is
case-insensitive, an unquoted, lower-case string, otherwise the double-quoted form. If
false
, always use the double-quoted form (this is slightly more efficient since we
don't need to inspect the string).Copyright © 2017–2024. All rights reserved.
