classBisonPreambleReader
final class BisonPreambleReaderRestricted visibility: declared "@visibility root". Code outside that scope must not name this declaration.
Reads the declarations section of a Bison grammar.
The section ends at the %% that opens the rules, and that separator is consumed here so the rules reader starts on a rule. A declaration whose arguments do not match its directive is skipped to its declaration boundary. Reading then continues with the next declaration in the same source section.
Methods§
