classPackedRows
final class PackedRows
implements ActionRowsRestricted visibility: declared "@visibility root". Code outside that scope must not name this declaration.
Action rows kept packed in binary and decoded one state at a time.
A full SQL grammar has hundreds of thousands of actions, while a parse visits a few hundred states, so rows are unpacked on first use and remembered.
Methods§
public function __construct(private string $blob, private list<int> $offsets)Parameters
$blob | string | Every row, packed as the codec writes them |
$offsets | list<int> | Byte offset of each state's row, with one more for the end |
public function row(int $state): array<int, int>Answers the explicit actions of one state.
Parameters
$state | int | State number |
Returns
array<int, int> Action code by symbol numberTest cases 2
