Reads endpoints and optional relation groups from one statement.
Methods§
public function __construct(private RelationCursor $cursor)Reads from the supplied statement cursor.
Parameters
$cursor | RelationCursor |
public function parseStatement(): list<Relation>|stringA statement is either a bare table name or one relation, which expands to several when its target is a group.

public function buildRelations(
ColumnRef $left,
RelationKind $kind,
list<ColumnRef> $targets,
bool $leftOptional,
bool $rightOptional,
): list<Relation>A grouped target expands to one relation per endpoint, so grouping is only ever a shorthand for repeating the left end.
Parameters
$left | ColumnRef | |
$kind | RelationKind | |
$targets | list<ColumnRef> | |
$leftOptional | bool | |
$rightOptional | bool |
Returns
