SniffedColumns

Read onlyYes

FinalYes

One unit's fold, done: the column types in first-seen order and the rows they were observed over.

Properties

$rows : int
$types : array<string|int, mixed>

Methods

__construct() : mixed
fromArray() : self
merge() : self: Merge left-to-right in listing order: name order follows first-seen, so a different bracketing of the name sequence changes the definition order (never the types).
normalize() : array{columns: list}>, rows: int}: A numeric column name is an int key here and a string in the JSON: the name travels as a string either way.

__construct()


    public
                    __construct(array<string|int, Type<string|int, mixed>> $types, int<0, max> $rows[, TypeWidener $widener = new TypeWidener() ]) : mixed

Parameters

$types : array<string|int, Type<string|int, mixed>>: first-seen order: header names first, then names met only in rows
$rows : int<0, max>

fromArray()


    public
            static        fromArray(array<string|int, mixed> $data) : self

Parameters

$data : array<string|int, mixed>: the shape of normalize()

Return values

merge()

Merge left-to-right in listing order: name order follows first-seen, so a different bracketing of the name sequence changes the definition order (never the types).

Parameters

$other : self
$unionByName : bool

Return values

self

normalize()

A numeric column name is an int key here and a string in the JSON: the name travels as a string either way.


    public
                    normalize() : array{columns: list}>, rows: int}

Return values

array{columns: list}>, rows: int}
