int64_t childCount ( ) const Get current number of records in a CompressedVectorNode. For a CompressedVectorNode with an active CompressedVectorWriter, the returned number will reflect any writes completed. Precondition: The destination ImageFile must be open (i.e. destImageFile().isOpen()). Postcondition: No visible state is modified. Returns: Current number of records in CompressedVectorNode. Exceptions: E57_ERROR_IMAGEFILE_NOT_OPEN E57_ERROR_INTERNAL All objects in undocumented state See also: CompressedVectorCreate.cpp example, CompressedVectorNode::reader, CompressedVectorNode::writer
