Abstract Interfaces

Abstract Interface	Location	Description
boundary_data_destroy_iface	rdb_ocean_boundary_data
boundary_data_update_iface	rdb_ocean_boundary_data	Refresh `bc%data_*` (and any other time-varying fields) for the current outer-step wall time `t` (s).
default_string_iface	rdb_nml_schema	Captured default value, formatted for namelist output.
diag_emit_proc	rdb_ocean_diag	Optional post-fire emit hook. Called by `step` once per cadence-fire AFTER the log line; used by the NetCDF writer to append a slice for the var that just fired. Kept abstract so the diag module stays free of NetCDF / I/O-server deps — `rdb_ocean_diag_netcdf` provides the concrete implementation.
diag_fill_proc	rdb_ocean_diag	Fill routine signature. `state_handle` is polymorphic so this module stays decoupled from `ocean_state_t` (which itself composes `ocean_diag_t`). Implementations live in `rdb_ocean_diag_fills` and do a `select type` cast to the concrete ocean state inside the body. `buf` is the pre-allocated output buffer the manager owns.
diag_remap_proc	rdb_ocean_diag	Vertical-remap routine signature. Called by the manager after `fill` when a var’s `output_vgrid` is not LAYER. `layer_buf` is the manager-owned native-grid scratch the fill wrote into; `output_buf` is the remap target on the configured output vgrid (z-levels / isopycnals / 2D). State-side data needed for the remap (e.g. `h_layer`, bathy) is fetched via `select type` on `state_handle`. Read more…
group_check_iface	rdb_nml_schema	Cross-key validation callback. Empty string = OK; a non-empty string is appended to the collected errors.
is_default_iface	rdb_nml_schema	True if the current target value equals the captured default.
parse_tokens_iface	rdb_nml_schema	Validate `values` and assign through the target pointer. On success `err_msg` is left unallocated.
value_string_iface	rdb_nml_schema	Current target value, formatted for namelist output.
