Detailed Description

Provides lookup and convenience functions for querying cards and their printings.

The CardDatabaseQuerier class offers various lookup helpers for retrieving card information (e.g., CardInfoPtr, ExactCard, and PrintingInfo) from a CardDatabase. It also applies user printing preferences via ICardPreferenceProvider when determining preferred printings.

Parameters

cardNames List of exact card names.

Returns: List of CardInfoPtr objects for which a match was found.

Looks up the cardInfos for a list of card names.

Parameters

cardNames The card names to look up

Returns: A List of CardInfoPtr. Any failed lookups will be ignored and dropped from the resulting list

nodiscard

Resolves multiple CardRefs into ExactCards.

Failed entries are not included in the result.

Parameters

cardRefs List of card references.

Returns: List of successfully resolved ExactCards.

Looks up the cards corresponding to the CardRefs. If the providerId is empty, will default to the preferred printing. If providerId is given but not found, the PrintingInfo will be empty.

Parameters

cardRefs The cards to look up. If providerId is empty for an entry, will default to the preferred printing for that entry. If providerId is given but not found, the PrintingInfo will be empty for that entry.
