Detailed Description

A container for an HTTP-legal time/date indication.

This can accept a string from an HTTP header and will decode it into a C time_t value; conversely, it can accept a time_t value and encode it for output as a string.

HTTPDate::HTTPDate (   )  [inline]

Definition at line 31 of file httpDate.I. References INLINE. Referenced by compare_to(), and operator=().

HTTPDate::HTTPDate (  time_t  time  )  [inline]

Definition at line 42 of file httpDate.I. References INLINE.

HTTPDate::HTTPDate (  const string &  format  )

Decodes the string into a sensible date. Returns 0 (!is_valid()) if the string cannot be correctly decoded. Definition at line 51 of file httpDate.cxx.

HTTPDate::HTTPDate (  const HTTPDate &  copy  )  [inline]

Definition at line 53 of file httpDate.I. References _time.

Member Function Documentation

int HTTPDate::compare_to (  const HTTPDate &  other  )  const [inline]

Returns a number less than zero if this HTTPDate sorts before the other one, greater than zero if it sorts after, or zero if they are equivalent. Definition at line 174 of file httpDate.I. References _time, HTTPDate(), and INLINE.

string HTTPDate::get_string (   )  const

Definition at line 243 of file httpDate.cxx. References months.

time_t HTTPDate::get_time (   )  const [inline]

Returns the date as a C time_t value. Definition at line 109 of file httpDate.I. References _time, and INLINE.

string HTTPDate::get_token (  const string &  str, size_t &  pos )  [static, private]

Extracts the next token from the string starting at the indicated position. Returns the token and updates pos. When the last token has been extracted, returns empty string. A token is defined as a contiguous sequence of digits or letters. If it is a sequence of letters, the function quietly truncates it to three letters before returning, and forces the first letter to capital and the second two to lowercase. If it is a sequence of digits, the function also returns the next character following the last digit (unless it is a letter). Definition at line 346 of file httpDate.cxx.

bool HTTPDate::input (  istream &  in  )

Definition at line 273 of file httpDate.cxx.

bool HTTPDate::is_valid (   )  const [inline]

Returns true if the date is meaningful, or false if it is -1 (which generally indicates the source string could not be parsed.). Definition at line 96 of file httpDate.I. References _time.

HTTPDate HTTPDate::now (   )  [inline, static]

Returns an HTTPDate that represents the current time and date. Definition at line 79 of file httpDate.I. References _time, INLINE, and time_t.

bool HTTPDate::operator!= (  const HTTPDate &  other  )  const [inline]

Definition at line 133 of file httpDate.I. References _time, and INLINE.
