Public Member Functions

Creators
 DateValue ()
 Default constructor.
 DateValue (int year, int month, int day)
 Constructor.
virtual ~DateValue ()
 Virtual destructor.
Manipulators
DateValueoperator= (const DateValue &rhs)
 Assignment operator.
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 setDate (const Date &src)
 Set the date.
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.

 Write value to a character data buffer.
virtual const DategetDate () const
 Return date struct containing date 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. .
virtual long toLong (long n=0) const
 Convert the n-th component of the value to a long. The behaviour of this method may be undefined if there is no n-th component.
virtual float toFloat (long n=0) const
 Convert the n-th component of the value to a float. The behaviour of this method may be undefined if there is no n-th component.
virtual Rational toRational (long n=0) const
 Convert the n-th component of the value to a Rational. The behaviour of this method may be undefined if there is no n-th component.

Detailed Description

Value for simple ISO 8601 dates

This class is limited to parsing simple date strings in the ISO 8601 format CCYYMMDD (century, year, month, day).


Member Function Documentation

long Exiv2::DateValue::copy byte buf,
ByteOrder  byteOrder = invalidByteOrder
const [virtual]
 

Write value to a character data buffer.

The user must ensure that the buffer has enough memory. Otherwise the call results in undefined behaviour.

Note:
The byte order is required by the interface but not used by this method, so just use the default.
Parameters:
buf Data buffer to write to.
byteOrder Byte order. Not used.
Returns:
Number of characters written.

Implements Exiv2::Value.

int Exiv2::DateValue::read const std::string &  buf  )  [virtual]
 

Set the value to that of the string buf.

Parameters:
buf String containing the date
Returns:
0 if successful
1 in case of an unsupported date format

Implements Exiv2::Value.

int Exiv2::DateValue::read const byte buf,
long  len,
ByteOrder  byteOrder = invalidByteOrder
[virtual]
 

Read the value from a character buffer.

Note:
The byte order is required by the interface but not used by this method, so just use the default.
Parameters:
buf Pointer to the data buffer to read from
len Number of bytes in the data buffer
byteOrder Byte order. Not needed.
Returns:
0 if successful
1 in case of an unsupported date format

Implements Exiv2::Value.

virtual float Exiv2::DateValue::toFloat long  n = 0  )  const [inline, virtual]
 

Convert the n-th component of the value to a float. The behaviour of this method may be undefined if there is no n-th component.

Returns:
The converted value.

Implements Exiv2::Value.

long Exiv2::DateValue::toLong long  n = 0  )  const [virtual]
 

Convert the n-th component of the value to a long. The behaviour of this method may be undefined if there is no n-th component.

Returns:
The converted value.

Implements Exiv2::Value.

virtual Rational Exiv2::DateValue::toRational long  n = 0  )  const [inline, virtual]
 

Convert the n-th component of the value to a Rational. The behaviour of this method may be undefined if there is no n-th component.

Returns:
The converted value.

Implements Exiv2::Value.
