equalByPhysical() : bool
equalities() : array<int, mixed>: Element physicals carry their owner document, so elements, and lists of them, compare by their own markup.
equality() : array<int, mixed>: NaN is the one float not === to itself: it becomes the string 'NaN', so NaN equals NaN.
instants() : array<int, int|null>: A date's physical days on a datetime's microsecond scale, so a date and a datetime at the same instant compare and hash equal.

orderings() : array{list, list}

                    equalByPhysical(Type<string|int, mixed> $type) : bool

bool

Element physicals carry their owner document, so elements, and lists of them, compare by their own markup.

                    equalities(Type<string|int, mixed> $type, array<int, mixed> $physicals) : array<int, mixed>

array<int, mixed> —

=== on these is value equality

NaN is the one float not === to itself: it becomes the string 'NaN', so NaN equals NaN.


    public
                    equality(Column $column) : array<int, mixed>

array<int, mixed> —

=== on these is value equality

A date's physical days on a datetime's microsecond scale, so a date and a datetime at the same instant compare and hash equal.


    public
                    instants(array<int, mixed> $days) : array<int, int|null>

array<int, int|null>

                    ordering(Column $column) : array<int, mixed>

array<int, mixed> —

PHP <, <=, <=> on these order the values; uuid, json, enum, xml and html by their physical bytes


    public
                    orderings(Column $first, Column $second) : array{list, list}

array{list, list}
