Function Documentation

void dfa_state_init (  DFA_INFO *  dinfo  )

Initialize and allocate DFA state information list in the grammar. Parameters: dinfo  [i/o] DFA grammar Definition at line 35 of file rddfa.c. Referenced by multigram_exec(), rddfa(), rddfa_fd(), and rddfa_sd().

void dfa_state_expand (  DFA_INFO *  dinfo, int  needed )

Expand the state information list to the required length. Parameters: dinfo  [i/o] DFA grammar needed  [in] required new length Definition at line 56 of file rddfa.c. Referenced by dfa_append(), and rddfa_line().

boolean rddfa (  FILE *  fp, DFA_INFO *  dinfo )

Top loop function to read DFA grammar via file pointer Parameters: fp  [in] file pointer that points to the DFA grammar data dinfo  [out] the read data will be stored in this DFA grammar structure Returns: TRUE on success, FALSE on failure. Definition at line 79 of file rddfa.c. Referenced by init_dfa().

boolean rddfa_fd (  int  fd, DFA_INFO *  dinfo )

Top loop function to read DFA grammar via file descriptor Parameters: fd  [in] file descriptor that points to the DFA grammar data dinfo  [out] the read data will be stored in this DFA grammar structure Returns: TRUE on success, FALSE on failure. Definition at line 109 of file rddfa.c.

boolean rddfa_sd (  int  sd, DFA_INFO *  dinfo )

Top loop function to read DFA grammar via socket descriptor Parameters: sd  [in] socket descriptor that points to the DFA grammar data dinfo  [out] the read data will be stored in this DFA grammar structure Returns: TRUE on success, FALSE on failure. Definition at line 139 of file rddfa.c.

boolean rddfa_line (  char *  line, DFA_INFO *  dinfo, int *  state_max, int *  arc_num, int *  terminal_max )

Parse the input line and set grammar information, one by line. Parameters: line  [in] text buffer that holds a line of DFA file dinfo  [i/o] the read data will be appended to this DFA data state_max  [i/o] maximum number of state id appeared, will be updated arc_num  [i/o] number of read arcs, will be updated terminal_max  [i/o] maximum number of state id appended, will be updated Returns: TRUE if the line was successfully parsed, FALSE if failed. Definition at line 172 of file rddfa.c. Referenced by rddfa(), rddfa_fd(), and rddfa_sd().

void dfa_append (  DFA_INFO *  dst, DFA_INFO *  src, int  soffset, int  coffset )

Append the DFA state information to other Parameters: dst  [i/o] DFA grammar src  [i/o] DFA grammar to be appended to dst soffset  [in] offset state number in dst where the new state should be stored coffset  [in] category id offset in dst where the new data should be stored Definition at line 230 of file rddfa.c. Referenced by multigram_build_append().
