Detailed Description

Sequence of shared_ptr<DataSlice> tile parts parsed from either TLM or SOT marker.

Constructor & Destructor Documentation

~TPSeq()

grk::TPSeq::~TPSeq ( )

default

Destroys a TPSeq.

Member Function Documentation

complete()

void grk::TPSeq::complete ( uint64_t tileStreamOffset )

inline

Completes calculations such as absolute tile part offsets, which are not available when TLM markers are parsed.

Parameters

tileStreamOffset

tile stream offset in code stream

References signalledNumTileParts_, and grk::SharedPtrSeq< DataSlice >::size().

push_back()

bool grk::TPSeq::push_back ( uint8_t tilePart, uint8_t numTileParts, uint64_t offset, uint32_t length )

inline

Pushes a new tile part to the back of the sequence.

Parameters

tilePart	tile part index
numTileParts	number of tile parts in tile
offset	tile part start position
length	tile part length

Returns

true if successful

References grk::grklog, grk::SharedPtrSeq< T >::push_back(), signalledNumTileParts_, and grk::SharedPtrSeq< DataSlice >::size().

reset()

void grk::TPSeq::reset ( )

inline

References grk::SharedPtrSeq< DataSlice >::clear(), and signalledNumTileParts_.

Member Data Documentation

signalledNumTileParts_

uint8_t grk::TPSeq::signalledNumTileParts_ = 0

private

Number of tile parts signalled in code stream This number is either explicitly stored in SOT, or deduced from TLM markers.
