#include <rw/http/RWHttpDate.h>

RWHttpDate maintains the date and time. It outputs the date as a string that conforms to the HTTP/1.0 date specification.

RWHttpDate();

Constructs a default RWHttpDate object. Internal date and time are initialized to the current date and time, respectively.

RWHttpDate(const RWDateTime& dt);

Constructs an RWHttpDate object with the internal date and time set to those in dt.

RWHttpDate(const RWCString& str);

Constructs an RWHttpDate object with the input str. The str argument must be an HTTP/1.1-compliant date string. The str is parsed for date and time, and the internals are set to the result. If str cannot be parsed, an invalid date is constructed.

HTTP/1.1 defines the following formats as acceptable date strings:

• Sun, 06 Nov 1994 08:49:37 GMT; RFC 822, updated by RFC 1123

• Sunday, 06-Nov-94 08:49:37 GMT; RFC 850, obsoleted by RFC 1036

• Sun Nov 6 08:49:37 1994; ANSI C's asctime() format

RWCString
asString() const;

Returns the interna l date and time formatted to comply with the HTTP/1.1 specification. The RWCString should contain 7-bit US-ASCII data. Throws RWInternalErr if isValid is false.

RWDateTime
getDate() const;

Returns an RWDateTime constructed on the date associated with the RWHttpDate object.

bool
isValid() const;

Returns true if the internal RWDateTime is not a sentinel value.

void
setDate(const RWCString& str);

Sets the internal date of the RWHttpDate object from the string str. The str argument must be an HTTP/1.1-compliant date string. The str is parsed for date and time, and the internals are set to the result. If str cannot be parsed, an invalid date is constructed. The RWCString should contain 7-bit US-ASCII data.

void
setDate(const RWDateTime& dt);

Sets the internal date of the RWHttpDate object to the date and time in dt.

ostream&
operator<<(ostream& s, const RWHttpDate& d);

Outputs an RWHttpDate object to an ostream.

istream&
operator>>(istream& s, RWHttpDate& d);

Restores an RWHttpDate from an istream into d, replacing the previous contents of d.

bool
operator==(const RWHttpDate& date1, const RWHttpDate& date2);
bool
operator!=(const RWHttpDate& date1, const RWHttpDate& date2);
bool
operator<(const RWHttpDate& date1, const RWHttpDate& date2);
bool
operator<=(const RWHttpDate& date1, const RWHttpDate& date2);
bool
operator>(const RWHttpDate& date1, const RWHttpDate& date2);
bool
operator>=(const RWHttpDate& date1, const RWHttpDate& date2);
