Interface CommandImplementors

public interface CommandImplementors
A factory interface for creating Command implementation objects.

This interface provides factory methods for instantiating various types of database commands used in the Doma framework. Each method creates a specific type of command object that is responsible for executing a corresponding Query object.

Implementations of this interface are responsible for creating the appropriate command objects based on the DAO method being executed. These command objects handle the execution of database operations (select, insert, update, delete, batch operations, etc.) and process the results.

The default implementations of these methods create standard command objects, but custom implementations can override these methods to provide specialized behavior or extended functionality for specific command types, such as custom transaction handling, logging, or performance monitoring.
