Constructor & Destructor Documentation

odtools::recorder::Recorder::Recorder ( const string &  url,
const uint32_t &  memorySegmentSize,
const uint32_t &  numberOfSegments,
const bool &  threading,
const bool &  dumpSharedData 


urlURL of the resource to be used for writing containers to.
memorySegmentSizeSize of a memory segment for storing shared memory data (like shared images).
numberOfSegmentsNumber of segments to be used.
threadingIf true recorder is using a background thread to dump shared memory data. If set to true recorder can be used in real-time required scenarios where it is embedded in user supplied apps; however, there is a risk that if the queue size (numberOfSegments) is chosen too small or the low-level disk I/O containers of type SharedImage or SharedMemory are dropped.
dumpSharedDataIf true, shared images and shared data will be stored as well.

This method returns the FIFO to be used for all containers except for shared memory segments.

Reference to queue to be used for queuing Containers.

void odtools::recorder::Recorder::registerRecorderDelegate ( const uint32_t &  containerID,
RecorderDelegate r 

This method registers a RecorderDelegate to process a specific Container differently.

void odtools::recorder::Recorder::store ( odcore::data::Container  c)

This method stores the given container. Depending on the container data type, either the FIFO queue is used or the one to handle shared memory data.
