Detailed Description

mootLexfreqsCompiler compiles lexical frequency parameter files into internal frequency tables, using a lexer/parser pair generated by Alain Coetmeur's flex++ and bison++ programs.

Member Function Documentation

parse_from_file()

mootLexfreqs* moot::mootLexfreqsCompiler::parse_from_file ( FILE *  file, const char *  filename = __null  )

inline

parse n-gram parameters from a C-stream. Returns NULL on error.

References parse_lexfreqs(), and select_streams().

parse_from_string()

mootLexfreqs* moot::mootLexfreqsCompiler::parse_from_string ( const char *  string, const char *  srcname = __null  )

inline

parse one regular expression from a C-string. Returns NULL on error.

References parse_lexfreqs(), and select_string().

select_streams()

void moot::mootLexfreqsCompiler::select_streams ( FILE *  in, FILE *  out, const char *  my_srcname = __null  )

inline

low-level input selection: input from a C-stream.

References moot::GenericLexer::select_streams().

Referenced by parse_from_file().

select_string()

void moot::mootLexfreqsCompiler::select_string ( const char *  in, const char *  my_srcname = __null  )

inline

low-level input selection: input from a C-string. WARNING: do NOT free the string 'in' until parsing has finished!

virtual

Implements mootLexfreqsParser.

Referenced by select_string().

parse_lexfreqs()

mootLexfreqs* moot::mootLexfreqsCompiler::parse_lexfreqs

(

)

low-level parsing method: parse all remaining n-grams from the currently selected input source.

Referenced by parse_from_file(), parse_from_string(), and select_string().

yyerror()

virtual void moot::mootLexfreqsCompiler::yyerror ( const char *  msg )

virtual

yyerror: report parse errors.

Reimplemented from mootLexfreqsParser.

Referenced by select_string().

yywarn()

virtual void moot::mootLexfreqsCompiler::yywarn ( const char *  msg )

virtual

yywarn: report parse warnings.

Reimplemented from mootLexfreqsParser.
