8. Dataflow Datatypes NCRR Fields Field::GenericField -- base class GenericField, data_at Holds Handle to Mesh Owns Data -- resize_fdata() [new DataType for FData{2,3}d] Freeze/Thaw (data) value(), set_value(), fdata() mesh(), mesh_detach() All fields derive from GenericField PointCloudMesh -> PointCloudField ImageMesh -> ImageField Persistent::Datatype::PropertyManager::Field::GenericField io(), PerTypeID lock/gen map of attrib/values data_at, interfaces Mesh::PropertyManager

9. Dataflow Datatypes NCRR Persistent Serialize data for disk I/O Eventually for distributed data marshalling Architecture independent Build atop XDR Slow for big data Optional circumvention for DenseMatrix Data files are (somewhat) human readable, but should ~not~ be generated / edited by anything other than SCIRun Use “convert” programs

10. Dataflow Datatypes NCRR Persistent void Matrix::io(Piostream& stream) { /* int version = */ stream.begin_class("Matrix", MATRIX_VERSION); PropertyManager::io(stream); stream.end_class(); } void ColumnMatrix::io(Piostream& stream) { /* int version = */stream.begin_class("ColumnMatrix", COLUMNMATRIX_VERSION); Matrix::io(stream); stream.io(rows); if(stream.reading()) { data=scinew double[rows]; } int i; for(i=0;i<rows;i++) stream.io(data[i]); stream.end_class(); }
