Function Documentation

int check_byte (  const char *  val  )

Check to see if val is a valid byte value. If not, generate an error message using parser_error(). There are two versions of check_byte(), one which calls parser_error() and prints an error message to stderr an one which calls parser_error() and generates and Error object. Returns: Returns: True if val is a byte value, False otherwise. Definition at line 157 of file parser-util.cc. References DBG.

int check_float32 (  const char *  val  )

Like check_byte() but for 64-bit float values. Definition at line 247 of file parser-util.cc. References DBG, and DODS_FLT_MAX.

int check_float64 (  const char *  val  )

Definition at line 275 of file parser-util.cc. References DBG, and DODS_DBL_MAX.

int check_int16 (  const char *  val  )

Like check_byte() but for 32-bit integers (check_uint() is for unsigned integers). Definition at line 183 of file parser-util.cc. References DODS_SHRT_MAX.

int check_int32 (  const char *  val  )

Definition at line 215 of file parser-util.cc. References DODS_INT_MAX.

int check_uint16 (  const char *  val  )

Definition at line 199 of file parser-util.cc.

int check_uint32 (  const char *  val  )

Definition at line 231 of file parser-util.cc.

int check_url (  const char *  val  )

Currently this function always returns true. Definition at line 332 of file parser-util.cc.

bool is_keyword (  string  id, const string &  keyword )

Definition at line 149 of file parser-util.cc. References DBG, downcase(), and prune_spaces().

Here is the call graph for this function:

void parse_error (  const string &  msg, const int  line_num, const char *  context )

Definition at line 128 of file parser-util.cc. Referenced by save_str().

void parse_error (  const char *  msg, const int  line_num, const char *  context )

Definition at line 99 of file parser-util.cc. References append_long_to_string().

Here is the call graph for this function:

void parse_error (  parser_arg *  arg, const char *  msg, const int  line_num, const char *  context )

Definition at line 68 of file parser-util.cc.

void save_str (  string &  dst, const char *  src, const   int )

Definition at line 144 of file parser-util.cc.

void save_str (  char *  dst, const char *  src, const int  line_num )

Given a string (const char *src), save it to the temporary variable pointed to by dst. If the string is longer than ID_MAX, generate and error indicating that src was truncated to ID_MAX characters during the copy operation. There are two versions of this function; one calls the version of parser_error() which writes to stderr. The version which accepts the parser_arg *arg argument calls the version of parser_error() which generates and Error object. Returns: void Definition at line 133 of file parser-util.cc.
