The GdaDataModelBdb object allows to access the contents of a Berkeley DB database as a GdaDataModel object.
By default the resulting GdaDataModel contains only two columns (named "key" and "data") of type
GDA_TYPE_BINARY, but this object can be subclassed to convert the key or data part of a BDB record
into several columns (implement the create_key_columns()
, create_data_columns()
, get_key_part()
, and get_data_part()
virtual methods).
GdaDataModel * gda_data_model_bdb_new (const gchar *filename
,const gchar *db_name
);
Creates a new GdaDataModel object to access the contents of the Berkeley DB file file
,
for the database db_name
