Detailed Description

Information for adding a subblock to a CZI-file with ICziWriter. Here we add the information about the payload-data. We employ a pull-based model, where the caller has to supply callback-functions for delivering the data.

Constructor & Destructor Documentation

◆ AddSubBlockInfo()

libCZI::AddSubBlockInfo::AddSubBlockInfo ( const AddSubBlockInfoBase & other )

inlineexplicit

Copy-Constructor which copies all information from the specified base-class object.

Parameters

other The other object of type AddSubBlockInfoBase from which information will be copied.

Member Function Documentation

◆ Clear()

void libCZI::AddSubBlockInfo::Clear ( )

inlineoverridevirtual

Clears this object to its blank/initial state.

Reimplemented from libCZI::AddSubBlockInfoBase.

Member Data Documentation

◆ getAttachment

std::function<bool(int callCnt, size_t offset, const void*& ptr, size_t& size)> libCZI::AddSubBlockInfo::getAttachment

The functor will be called to retrieve the subblock's attachment. The function must set the arguments 'ptr' and 'size', and the memory pointed to must be valid until the next call into the functor (or returning from the 'SyncAddSubBlock' method). The argument 'callCnt' is incremented with each call (starting from 0), and 'offset' is incremented by the number of bytes already retrieved. The functor will be called until the amount of bytes specified by 'sizeAttachment" has been retrieved or if it returns false. If returning false, the subblock-attachment is filled with zeroes (if necessary) so that 'sizeAttachment' bytes are reached.

◆ getData

std::function<bool(int callCnt, size_t offset, const void*& ptr, size_t& size)> libCZI::AddSubBlockInfo::getData

The functor will be called to retrieve the subblock's data. The function must set the arguments 'ptr' and 'size', and the memory pointed to must be valid until the next call into the functor (or returning from the 'SyncAddSubBlock' method). The argument 'callCnt' is incremented with each call (starting from 0), and 'offset' is incremented by the number of bytes already retrieved. The functor will be called until the amount of bytes specified by 'sizeData" has been retrieved or if it returns false. If returning false, the subblock-data is filled with zeroes (if necessary) so that 'sizeData' bytes are reached.

◆ getMetaData

std::function<bool(int callCnt, size_t offset, const void*& ptr, size_t& size)> libCZI::AddSubBlockInfo::getMetaData

The functor will be called to retrieve the subblock's metadata. The function must set the arguments 'ptr' and 'size', and the memory pointed to must be valid until the next call into the functor (or returning from the 'SyncAddSubBlock' method). The argument 'callCnt' is incremented with each call (starting from 0), and 'offset' is incremented by the number of bytes already retrieved. The functor will be called until the amount of bytes specified by 'sizeMetadata" has been retrieved or if it returns false. If returning false, the subblock-metadata is filled with zeroes (if necessary) so that 'sizeMetadata' bytes are reached.
