Functions
Character check , without side effect on the current position
utility functions for checking characters, without changing the current position of the input string being parsed.
bool	AstFromString::afs_is_digit ()
	Check if the current character is a digit. The current position of the input string remains unchanged either way. More...
bool	AstFromString::afs_is_identifier_char ()
	Check if the current character is a legal identifier character, including letters, digits, '_' and '$' (For fortran). No side effect on the current position. More...
bool	AstFromString::afs_is_letter ()
	Check if the current character is a letter. No side effect on the current position of the input string. More...
bool	AstFromString::afs_is_lower_letter ()
	Check if the current character is a lower case letter. More...
bool	AstFromString::afs_is_upper_letter ()
	Check if the current character is a upper case letter. More...
Match with side effects (set c_parsed_node and advance the current position of character) if successful. Return false and have no side effects if the match fails.
utility functions for matching string, whitespace, identifiers, const etc. Successful match will advance the current position. entry point, declarations, types Follow the order of http://www.antlr.org/grammar/1153358328744/C.g
ROSE_DLL_API bool	AstFromString::afs_match_char (char c)

Expression
utility functions for parsing expressions and generate AST pieces for them. Successful match will advance the current position. The function names and grammars largely follow the conventions used in http://www.antlr.org/grammar/1153358328744/C.g. For example in the grammar shown, | means or, * means 0 or more repetition of the previous term , ? means 0 or 1 occurrence of the previous term. + means 1 or more occurrence.
