Member Function Documentation

◆ diff()

unsigned dballe::impl::Message::diff ( const dballe::Message & msg ) const

overridevirtual

Details of the differences found will be formatted using the wreport notes system (

See also: wreport/notes.h).

Returns: The number of differences found

Implements dballe::Message.

◆ downcast() [1/3]

static const Message& dballe::impl::Message::downcast ( const dballe::Message & o )

static

Return a reference to o downcasted as an impl::Message.

Throws an exception if o is not an impl::Message.

◆ downcast() [2/3]

static Message& dballe::impl::Message::downcast ( dballe::Message & o )

static

Return a reference to o downcasted as an impl::Message.

Throws an exception if o is not an impl::Message.

◆ downcast() [3/3]

static std::shared_ptr<Message> dballe::impl::Message::downcast ( std::shared_ptr< dballe::Message > o )

static

Returns a pointer to o downcasted as an impl::Message.

Throws an exception if o is not an impl::Message.

tr	The Trange to query

Returns: The context found

◆ query_data()

std::unique_ptr<dballe::CursorData> dballe::impl::Message::query_data ( const Query & query ) const

overridevirtual

Query the variables in the message.

Parameters

query The query data (note: currently ignored)

Returns: The cursor to use to iterate over the results

Implements dballe::Message.

◆ query_station_data()

std::unique_ptr<dballe::CursorStationData> dballe::impl::Message::query_station_data ( const Query & query ) const

overridevirtual

Implements dballe::Message.

◆ query_stations()

std::unique_ptr<dballe::CursorStation> dballe::impl::Message::query_stations ( const Query & query ) const

overridevirtual

Return a Cursor to access the station information in the message.

The cursor will have only one result, with the one station present in the message, contain all station vars.

Parameters

query The query data (note: currently ignored)

Returns: The cursor to use to iterate over the results

Implements dballe::Message.

◆ remove_context()

bool dballe::impl::Message::remove_context	(	const Level &	lev,
		const Trange &	tr
	)

Remove a context from the message.

Returns: true if the context was removed, false if it did not exist

◆ set()

void dballe::impl::Message::set	(	const Shortcut &	shortcut,
		const wreport::Var &	var
	)

Add or replace a value.

Parameters

shortcut	Shortcut ID of the value to set
var	The Var with the value to set

◆ sounding_pack_levels()

void dballe::impl::Message::sounding_pack_levels ( )

Remove the sounding significance from the level descriptions and pack together the data at the same pressure level.

This is used to postprocess data after decoding, where the l2 field of the level description is temporarily used to store the vertical sounding significance, to simplify decoding.
