Detailed Description

A commodity is something of value that is easily tradeable or sellable; for example, currencies, stocks, bonds, grain, copper, and oil are all commodities.

This file provides an API for defining a commodities, and for working with collections of commodities. All GnuCash financial transactions must identify the commodity that is being traded.

Warning
The system used here does not follow the object handling and identification system (GncGUID's, Entities, etc.) that the other parts of GnuCash use. The API really should be ported over. This would allow us to get rid of the commodity table routines defined below.

Macro Definition Documentation

◆ gnc_commodity_get_kvp_frame

#define gnc_commodity_get_kvp_frame (   cm)    qof_instance_get_slots(QOF_INSTANCE(cm))

Get the internal KVP from of the currency.

You should rather use the individual accessors for individual properties

Definition at line 982 of file gnc-commodity.h.

◆ GNC_COMMODITY_NS_LEGACY

#define GNC_COMMODITY_NS_LEGACY   "GNC_LEGACY_CURRENCIES"

The commodity namespace definitions are used to tag a commodity by its type, or a stocks by the exchange where it is traded.

The LEGACY name is only used by the file i/o routines, and is converted to another commodity namespace before it is seen by the rest of the system. The ISO namespace represents currencies. With the exception of the NASDAQ namespace (which is used once in the binary importer) the rest of the namespace declarations are only used to populate an option menu in the commodity selection window.

Definition at line 98 of file gnc-commodity.h.

Enumeration Type Documentation

◆ QuoteSourceType

The quote source type enum account types are used to determine how the transaction data in the account is displayed.

These values can be safely changed from one release to the next.

Enumerator
SOURCE_SINGLE 

This quote source pulls from a single specific web site.

For example, the yahoo_australia source only pulls from the yahoo web site.

SOURCE_MULTI 

This quote source may pull from multiple web sites.

For example, the australia source may pull from ASX, yahoo, etc.

SOURCE_UNKNOWN 

This is a locally installed quote source that gnucash knows nothing about.

May pull from single or multiple locations.

SOURCE_CURRENCY 

The special currency quote source.

Definition at line 124 of file gnc-commodity.h.

126  SOURCE_SINGLE = 0,
130  SOURCE_MULTI,
137  SOURCE_MAX,

Function Documentation

◆ gnc_commodity_compare()

int gnc_commodity_compare ( const gnc_commodity *  a,
const gnc_commodity *  b 
)

This routine returns 0 if the two commodities are equal, 1 otherwise.

Commodities are equal if they have the same namespace, mnemonic, fullname, exchange private code and fraction. This function is useful for list-traversal comparison purposes where The semantics are 0, <0, or >0 (equal, greater than, less than) rather than "true or false"

Definition at line 1639 of file gnc-commodity.c.

1640 {

1647  return 1;
1648  }
1649 }
gboolean gnc_commodity_equal(const gnc_commodity *a, const gnc_commodity *b)
This routine returns TRUE if the two commodities are equal.

◆ gnc_commodity_decrement_usage_count()

void gnc_commodity_decrement_usage_count ( gnc_commodity *  cm)

Decrement a commodity's internal counter that tracks how many accounts are using that commodity.

For currencies, this may have the side effect of disabling the commodity's quote flag.

Parameters
cmA pointer to a commodity data structure.

commA pointer to the commodity to add.
Returns
The added commodity. Null on error.
Note
The commodity pointer passed to this function should not be used after its return, as it may have been destroyed. Use the return value which is guaranteed to be valid.
