Detailed Description

Manages a collection of GribRecord objects representing multiple meteorological parameters at a single point in time.

While a GribRecord represents a single parameter's grid data (e.g., temperature or wind-x component), GribRecordSet bundles related records together to provide a complete meteorological picture for one timestamp. For example, it might contain:

• Surface winds (both X and Y components)
• Wind components at different pressure levels (850hPa, 700hPa, etc.)
• Temperature, pressure, humidity
• Wave and current data

Records are stored in a fixed-size array where each index corresponds to a specific parameter as defined by the Idx_* enumeration. The set can either:

• Own records (usually interpolated records it created)
• Reference records (owned by the GRIB file reader)

Note

This class handles memory management for records it owns via m_GribRecordUnref

Constructor & Destructor Documentation

GribRecordSet()

GribRecordSet::GribRecordSet ( unsigned int  id )

inline

Creates an empty record set.

Parameters

id	Unique identifier for this record set. The id is used to uniquely identify this record set within a GRIB file.

Definition at line 166 of file grib_record_set.h.

~GribRecordSet()

virtual GribRecordSet::~GribRecordSet ( )

inlinevirtual

Definition at line 173 of file grib_record_set.h.

Member Function Documentation

RemoveGribRecords()

void GribRecordSet::RemoveGribRecords ( )

inline

Removes and deletes all GRIB records owned by this set.

Records not owned by this set are left untouched.

Definition at line 198 of file grib_record_set.h.

SetUnRefGribRecord()

void GribRecordSet::SetUnRefGribRecord ( int  i, GribRecord *  pGR  )

inline

Sets a GRIB record that this set owns and will be responsible for deleting.

Typically used for interpolated records created between two time points. The set takes ownership and will delete the record when appropriate.

Parameters

i	Index in the record array where to store the record
pGR	Pointer to the GRIB record to store

Definition at line 184 of file grib_record_set.h.

Member Data Documentation

m_GribRecordPtrArray

GribRecord* GribRecordSet::m_GribRecordPtrArray[Idx_COUNT]

Array of pointers to GRIB records representing different meteorological parameters.

Each index corresponds to a specific parameter (wind, gust, wave, etc). Records may be owned by this set (tracked by m_GribRecordUnref) or referenced from elsewhere.

Definition at line 220 of file grib_record_set.h.

m_ID

unsigned int GribRecordSet::m_ID

Unique identifier for this record set.

Definition at line 210 of file grib_record_set.h.

m_Reference_Time

time_t GribRecordSet::m_Reference_Time

Reference time for this set of records, as the number of seconds since the epoch.

Definition at line 208 of file grib_record_set.h.
