Constructor & Destructor Documentation

§ DataSegment()

Nitf::DataSegment::DataSegment	(	NITFReaderManager &	,
		LTIOStreamInf &	,
		int	segmentNumber,
		lt_int64	headerOffset,
		lt_int64	headerLength,
		lt_int64	dataOffset,

Member Function Documentation

§ addMetadataLocal() [1/2]

LT_STATUS Nitf::DataSegment::addMetadataLocal ( LTIMetadataDatabase & db ) const

virtual

Implements Nitf::Segment.

§ addMetadataLocal() [2/2]

LT_STATUS Nitf::DataSegment::addMetadataLocal	(	LTIMetadataDatabase &	db,
		const char *	prefixOverride
	)		const

§ getData()

const lt_uint8* Nitf::DataSegment::getData ( ) const

This function returns the actual data of the data segment, as an array of bytes. The length of the array can be found by calling getDataLen().

Returns: the array of bytes of the data

§ getDataLen()

lt_uint32 Nitf::DataSegment::getDataLen ( ) const

This function returns the length of actual data of the data segment, in bytes.

Returns: the number of bytes of the data

§ getDESID()

const char* Nitf::DataSegment::getDESID ( ) const

This function returns the ID of the data segment.

Returns: the ID of the segment, as a string

§ getDESVER()

const char* Nitf::DataSegment::getDESVER ( ) const

This function returns the version of the data segment.

Returns: the version of the segment, as a string

§ initialize()

LT_STATUS Nitf::DataSegment::initialize ( )
