		int	yysym )

staticprivate

Compute post-reduction state.

Parameters

yystate	the current state
yysym	the nonterminal to push on the stack

◆ yy_pact_value_is_default_()

bool SEAMS::Parser::yy_pact_value_is_default_ ( int yyvalue )

staticprivate

Whether the given yypact_ value indicates a defaulted state.

Parameters

yyvalue the value to check

◆ yy_syntax_error_arguments_()

int SEAMS::Parser::yy_syntax_error_arguments_	(	const context &	yyctx,
		symbol_kind_type	yyarg[],
		int	yyargn ) const

private

The arguments of the error message.

void SEAMS::Parser::yypush_	(	const char *	m,
		state_type	s,
		YY_MOVE_REF(symbol_type)	sym )

private

Push a new look ahead token on the state on the stack.

Parameters

m	a debug message to display if null, no trace is output.
s	the state
sym	the symbol (for its value and location).

Warning: the contents of sym.value is stolen.

◆ yypush_() [2/2]

void SEAMS::Parser::yypush_	(	const char *	m,
		YY_MOVE_REF(stack_symbol_type)	sym )

private

Push a new state on the stack.

Parameters

m	a debug message to display if null, no trace is output.
sym	the symbol

Warning: the contents of s.value is stolen.

◆ yysyntax_error_()

std::string SEAMS::Parser::yysyntax_error_ ( const context & yyctx ) const

privatevirtual

Generate an error message.

Parameters

yyctx the context in which the error occurred.

◆ yytnamerr_()

std::string SEAMS::Parser::yytnamerr_ ( const char * yystr )

staticprivate

Convert the symbol name n to a form suitable for a diagnostic.

◆ yytranslate_()

Parser::symbol_kind_type SEAMS::Parser::yytranslate_ ( int t )

staticprivate

Convert a scanner token kind t to a symbol kind. In theory t should be a token_kind_type, but character literals are valid, yet not members of the token_kind_type enum.
