All Implemented Interfaces:

Serializable

Enclosing class:

Lexicals.Identifier

public static final class Lexicals.Identifier.Pseudo
extends Lexicals.Identifier.Simple

Displays/deparses like a Simple identifier, but no singleton of this class matches anything but itself, to represent pseudo-identifiers like PUBLIC as a privilege grantee.

Field Details

PUBLIC

public static final Lexicals.Identifier.Pseudo PUBLIC

Instance intended to represent PUBLIC when used as a privilege grantee.

It would not be correct to use this instance for other special things that happen to be named PUBLIC, such as the PUBLIC schema. That is a real catalog object that has the actual name PUBLIC, and should be represented as a Simple with that name.

Note: through PG 14 at least, the database itself does not treat the public grantee in the way anticipated here; it is, instead, treated as an ordinary folding name "public" and forbidden as the name of any role. Therefore, a model of grantee roles would not need this symbol after all, but the definition will remain here illustrating the concept.

Method Details

equals

public boolean equals(Object other)

A Pseudo identifier instance is only equal to itself.

Overrides:

equals in class Lexicals.Identifier

Parameters:

other - Object to compare to

Returns:

true if two quoted Identifiers match exactly, or two non-quoted ones match in either the PostgreSQL or ISO SQL folded form, or a quoted one exactly matches either folded form of a non-quoted one.
