Exiv2::Internal::TiffSubIfd Class Reference

This class models a TIFF sub-directory (sub-IFD). A sub-IFD is an entry with one or more values that are pointers to IFD structures containing an IFD. The TIFF standard defines some important tags to be sub-IFDs, including the Exif and GPS tags. More...

Public Member Functions

Creators

TiffSubIfd (uint16_t tag, IfdId group, IfdId newGroup)

Default constructor.

virtual ~TiffSubIfd ()

Virtual destructor.

Protected Member Functions

Protected Creators

TiffSubIfd (const TiffSubIfd &rhs)

Copy constructor (used to implement clone()).

Protected Manipulators

virtual TiffComponent * doAddPath (uint16_t tag, TiffPath &tiffPath, TiffComponent *const pRoot, TiffComponent::AutoPtr object)

Implements addPath(). The default implementation does nothing.

virtual TiffComponent * doAddChild (TiffComponent::AutoPtr tiffComponent)

Implements addChild(). The default implementation does nothing.

virtual void doAccept (TiffVisitor &visitor)

Implements accept().

virtual void doEncode (TiffEncoder &encoder, const Exifdatum *datum)

Implements encode().

virtual uint32_t doWrite (IoWrapper &ioWrapper, ByteOrder byteOrder, int32_t offset, uint32_t valueIdx, uint32_t dataIdx, uint32_t &imageIdx)

Implements write(). Write the sub-IFD pointers to the ioWrapper, return the number of bytes written. The valueIdx and imageIdx arguments are not used.

Protected Accessors

virtual TiffSubIfd * doClone () const

Internal virtual copy constructor, implements clone().

virtual uint32_t doWriteData (IoWrapper &ioWrapper, ByteOrder byteOrder, int32_t offset, uint32_t dataIdx, uint32_t &imageIdx) const

Implements writeData(). Write the sub-IFDs to the ioWrapper. Return the number of bytes written.

virtual uint32_t doWriteImage (IoWrapper &ioWrapper, ByteOrder byteOrder) const

Implements writeImage(). Write the image data of each sub-IFD to the ioWrapper. Return the number of bytes written.

uint32_t doSize () const

Implements size(). Return the size of the sub-Ifd pointers.

virtual uint32_t doSizeData () const

Implements sizeData(). Return the sum of the sizes of all sub-IFDs.

virtual uint32_t doSizeImage () const

Implements sizeImage(). Return the sum of the image sizes of all sub-IFDs.
