Public Types

typedef std::auto_ptr< SonyMakerNoteAutoPtr
 Shortcut for a SonyMakerNote auto pointer.

Public Member Functions

Creators
 SonyMakerNote (bool alloc=true)
 Constructor. Allows to choose whether or not memory management is required for the makernote entries.
 SonyMakerNote (const SonyMakerNote &rhs)
 Copy constructor.
virtual ~SonyMakerNote ()
 Virtual destructor.
Manipulators
int readHeader (const byte *buf, long len, ByteOrder byteOrder)
 Read the makernote header from the makernote databuffer. This method must set the offset to the start of the IFD (start_), if needed (assuming that the required information is in the header). Return 0 if successful.
Accessors
int checkHeader () const
 Check the makernote header. This will typically check if a required prefix string is present in the header. Return 0 if successful.
AutoPtr create (bool alloc=true) const
 Return an auto-pointer to an newly created, empty instance of the same type as this. The makernote entries are not copied. The caller owns the new object and the auto-pointer ensures that it will be deleted.
AutoPtr clone () const
 Return an auto-pointer to a clone of this object. The caller owns the new object and the auto-pointer ensures that it will be deleted.

Detailed Description

MakerNote for Sony cameras.


Member Function Documentation

int Exiv2::SonyMakerNote::checkHeader  )  const [virtual]
 

Check the makernote header. This will typically check if a required prefix string is present in the header. Return 0 if successful.

Note:
The default implementation does nothing, assuming there is no header

Reimplemented from Exiv2::IfdMakerNote.

SonyMakerNote::AutoPtr Exiv2::SonyMakerNote::clone  )  const
 

Return an auto-pointer to a clone of this object. The caller owns the new object and the auto-pointer ensures that it will be deleted.

Note:
In non-alloc mode the clone potentially contains pointers to the same data buffer as the original. Use updateBase(byte* pNewBase) to adjust them.

Reimplemented from Exiv2::IfdMakerNote.

SonyMakerNote::AutoPtr Exiv2::SonyMakerNote::create bool  alloc = true  )  const
 

Return an auto-pointer to an newly created, empty instance of the same type as this. The makernote entries are not copied. The caller owns the new object and the auto-pointer ensures that it will be deleted.

Parameters:
alloc Memory management model for the newly created object. Indicates if memory required to store data should be allocated and deallocated (true) or not (false). If false, only pointers to the buffer provided to read() will be kept. See Ifd for more background on this concept.

Reimplemented from Exiv2::IfdMakerNote.

int Exiv2::SonyMakerNote::readHeader const byte buf,
long  len,
ByteOrder  byteOrder
[virtual]
 

Read the makernote header from the makernote databuffer. This method must set the offset to the start of the IFD (start_), if needed (assuming that the required information is in the header). Return 0 if successful.

Note:
The default implementation does nothing, assuming there is no header
