classQuotedLiteralScanner
final class QuotedLiteralScanner
implements BisonScannerRestricted visibility: declared "@visibility root". Code outside that scope must not name this declaration.
Consumes a quoted literal.
Bison spells a token's own text in single quotes and its alias in double quotes, so the quote character decides which lexeme was written. Both are read the same way, escapes included; only the resulting lexeme differs.
Methods§
public function handles(string $character): boolReports whether a quoted literal can start here.
Parameters
$character | string | A single character; never the empty string |
Returns
bool True for either quote characterTest cases 1

public function scan(SourceCursor $cursor): BisonTokenConsumes the literal including both quotes.
Parameters
$cursor | SourceCursor | Cursor positioned on the opening quote |
Returns
BisonToken The unescaped text between the quotesTest cases 4
