getFileBlock()

void ossimPdalFileReader::getFileBlock ( ossim_uint32  offset, ossimPointBlock &  block, ossim_uint32  maxNumPoints = 0xFFFFFFFF  ) const

virtual

Fetches up to maxNumPoints points at the given dataset <offset> in the order they appear in the data file.

Thread-safe implementation accepts a previously-allocated vector from the caller. The offset is set to offset + block.size (or EOF) upon exit, to permit sequencing with getNextBlock() implmented in base class.

Implements ossimPointCloudHandler.
