Detailed Description

Simple IO wrapper to ensure that the header is only written if there is any other data at all.

The wrapper is initialized with an IO reference and a pointer to a TIFF header. Subsequently the wrapper is used by all TIFF write methods. It takes care that the TIFF header is written to the IO first before any other output and only if there is any other data.

Constructor & Destructor Documentation

◆ IoWrapper()

Exiv2::Internal::IoWrapper::IoWrapper	(	BasicIo &	io,
		const byte *	pHeader,
		long	size,
		OffsetWriter *	pow
	)

brief Constructor.

The IO wrapper owns none of the objects passed in so the caller is responsible to keep them alive.

Member Function Documentation

◆ putb()

int Exiv2::Internal::IoWrapper::putb ( byte data )

Wraps the corresponding BasicIo::putb() method.

Writes the TIFF header to the IO, if it hasn't been written yet, followed by the data passed in the argument.

◆ write()

long Exiv2::Internal::IoWrapper::write	(	const byte *	pData,
		long	wcount
	)

Wraps the corresponding BasicIo::write() method.

Writes the TIFF header to the IO, if it hasn't been written yet, followed by the data passed in the arguments.
