source: XIOS/trunk/src/distribution_server.hpp @ 829

Last change on this file since 829 was 676, checked in by rlacroix, 9 years ago

Add support for indexed output.

If the new field attribute "indexed_output" is set to true and a mask is defined (either at grid, domain or axis level), the indexed data will be outputed instead of the full data with missing values.

See http://cfconventions.org/Data/cf-conventions/cf-conventions-1.5/build/cf-conventions.html#compression-by-gathering for more information.
