Public Types | |
typedef std::auto_ptr< TimeValue > | AutoPtr |
Shortcut for a TimeValue auto pointer. | |
Public Member Functions | |
Creators | |
TimeValue () | |
Default constructor. | |
TimeValue (int hour, int minute, int second=0, int tzHour=0, int tzMinute=0) | |
Constructor. | |
virtual | ~TimeValue () |
Virtual destructor. | |
Manipulators | |
| |
virtual int | read (const byte *buf, long len, ByteOrder byteOrder=invalidByteOrder) |
Read the value from a character buffer. | |
virtual int | read (const std::string &buf) |
Set the value to that of the string buf. | |
void | setTime (const Time &src) |
Set the time. | |
Accessors | |
| |
AutoPtr | clone () const |
Return an auto-pointer to a copy of itself (deep copy). The caller owns this copy and the auto-pointer ensures that it will be deleted. | |
virtual long | copy (byte *buf, ByteOrder byteOrder=invalidByteOrder) const |
Write value to a character data buffer. | |
virtual const Time & | getTime () const |
Return time struct containing time information. | |
virtual long | count () const |
Return the number of components of the value. | |
virtual long | size () const |
Return the size of the value in bytes. | |
virtual std::ostream & | write (std::ostream &os) const |
Write the value to an output stream. You do not usually have to use this function; it is used for the implementation of the output operator for Value, operator<<(std::ostream &os, const Value &value). | |
virtual long | toLong (long n=0) const |
Returns number of seconds in the day in UTC. | |
virtual float | toFloat (long n=0) const |
Returns number of seconds in the day in UTC converted to float. | |
virtual Rational | toRational (long n=0) const |
Returns number of seconds in the day in UTC converted to Rational. |
Value for simple ISO 8601 times.
This class is limited to handling simple time strings in the ISO 8601 format HHMMSS±HHMM where HHMMSS refers to local hour, minute and seconds and ±HHMM refers to hours and minutes ahead or behind Universal Coordinated Time.
Write value to a character data buffer.
The user must ensure that the buffer has enough memory. Otherwise the call results in undefined behaviour.
buf | Data buffer to write to. | |
byteOrder | Byte order. Not used. |

int Exiv2::TimeValue::read | ( | const std::string & | buf | ) | [virtual] |
Set the value to that of the string buf.
buf | String containing the time. |
Implements Exiv2::Value.
int Exiv2::TimeValue::read | ( | const byte * | buf, | |
long | len, | |||
ByteOrder | byteOrder = invalidByteOrder | |||
) | [virtual] |
Read the value from a character buffer.
buf | Pointer to the data buffer to read from | |
len | Number of bytes in the data buffer | |
byteOrder | Byte order. Not needed. |
