CompressedVectorReader reader ( const std::vector< SourceDestBuffer > &  dbufs ) Create an iterator object for reading a series of blocks of data from a CompressedVectorNode. Parameters: [in] dbufs Vector of memory buffers that will receive data read from a CompressedVectorNode. The pathNames in the dbufs must identify terminal nodes (i.e. node that can have no children: IntegerNode, ScaledIntegerNode, FloatNode, StringNode) in this CompressedVectorNode's prototype. It is an error for two SourceDestBuffers in dbufs to identify the same terminal node in the prototype. It is not an error to create a CompressedVectorReader for an empty CompressedVectorNode. Precondition: dbufs can't be empty The destination ImageFile must be open (i.e. destImageFile().isOpen()). The destination ImageFile can't have any writers open (destImageFile().writerCount()==0) This CompressedVectorNode must be attached (i.e. isAttached()). Returns: A smart CompressedVectorReader handle referencing the underlying iterator object.
