◆ isCompatible()

Wikimedia\Rdbms\DatabaseDomain::isCompatible ( $other )

Check whether the domain $other meets the specifications of this domain.

If this instance has a null database specifier, then $other can have any database specified, including the null, and likewise if the schema specifier is null. This is not transitive like equals() since a domain that explicitly wants a certain database or schema cannot be satisfied by one of another (nor null). If the prefix is empty and the DB and schema are both null, then the entire domain is considered unspecified, and any prefix of $other is considered compatible.

Parameters

DatabaseDomain | string $other
