Member Function Documentation

eof()

bool pgn_impl::InputMemory::eof ( ) const

inline

Returns true if there are no chars available.

Definition at line 308 of file pgn_lexer.h.

first_column()

bool pgn_impl::InputMemory::first_column ( ) const

inline

Returns true if the most recently extracted character was the first character of the line.

Definition at line 315 of file pgn_lexer.h.

last_column()

bool pgn_impl::InputMemory::last_column ( ) const

inline

Returns true if the most recently extracted character was the last character of the line.

Definition at line 319 of file pgn_lexer.h.

n_read()

std::size_t pgn_impl::InputMemory::n_read ( ) const

inline

Returns the number of chars read.

Definition at line 311 of file pgn_lexer.h.

read_line()

std::pair<const char*, const char*> pgn_impl::InputMemory::read_line ( )

inline

Returns the range of chars: [curr_char, '
').

The '
' char is left as the next character to extract.

Definition at line 323 of file pgn_lexer.h.

read_token()

template<typename Cond >

std::pair<const char*, const char*> pgn_impl::InputMemory::read_token ( Cond  cond )

inline

Returns the range of chars: [last_extracted_char, cond == true].

cond is not applied to last_extracted_char.

Definition at line 349 of file pgn_lexer.h.

read_until()

std::pair<const char*, const char*> pgn_impl::InputMemory::read_until ( char  delim )

inline

Returns the range of chars: [curr_char, delim).

The delim char is skipped.

Definition at line 331 of file pgn_lexer.h.

read_while()

template<typename Cond >

std::pair<const char*, const char*> pgn_impl::InputMemory::read_while ( Cond  cond )

inline

Returns the range of chars: [curr_char, cond == true].

Definition at line 340 of file pgn_lexer.h.

sbumpc()

char pgn_impl::InputMemory::sbumpc ( )

inline

Reads one character and advances the input sequence by one character.

Definition at line 296 of file pgn_lexer.h.

sungetc()

void pgn_impl::InputMemory::sungetc ( )

inline

Makes the most recently extracted character available again.

Definition at line 302 of file pgn_lexer.h.
