final class SqlGenerator
Restricted visibility: declared "@visibility root". Code outside that scope must not name this declaration.

Derives terminals, rewrites structural constraints, and realizes lexemes once. Dialect definitions supply the syntax and boundary rules; no completed SQL is retried or repaired.

Properties§

public ?TerminalSequence $lastSequence = null
source§

The latest terminal sequence retains both the original grammar choices and their rewrites.

public ?ResolvedOutput $lastOutput = null
source§

Selected lexical candidates and resolved boundary rules from the latest generation.

Methods§

public function __construct(
    private Grammar $grammar,
    private Generator $faker,
    private LexicalGrammar $lexicalGrammar,
    private ?TokenRewriter $rewriter = null,
    private Closure(string|null): string|null $startSymbol = null,
    private ?GrammarCoverage $coverage = null,
    ?Grammar $original = null,
)
100%source§

Binds grammar, lexical definitions and structural rules before generation starts.

Parameters

$grammarGrammar
$fakerGenerator
$lexicalGrammarLexicalGrammar
$rewriter?TokenRewriter
$startSymbolClosure(string|null): string|nullResolves explicitly requested release aliases

public function generate<TRequiresNonEmpty of bool>(GenerationPlan<TRequiresNonEmpty> $plan): (TRequiresNonEmpty is true ? non-empty-string : string)
100%source§

Generates once through the declared stages; candidate absence remains an error.

Parameters

$planGenerationPlan<TRequiresNonEmpty>

Returns

(TRequiresNonEmpty is true ? non-empty-string : string)

Throws

GenerationException When the grammar or plan cannot produce the requested output
LexicalException When no applicable lexical realization exists

public function realize(string $root, GenerationPlan<bool> $plan): string
100%source§

Derives and realizes once, retaining source selection independently of transformed output.

Parameters

$rootstring
$planGenerationPlan<bool>

Returns

string

Throws

GenerationException When derivation cannot complete
LexicalException When a terminal has no compatible realization
