Package org.apache.calcite.util

Interface JdbcType<T extends @Nullable Object>

Type Parameters:

T - Value type

public interface JdbcType<T extends @Nullable Object>

Maps Java types to their corresponding getters in JDBC.

In future we could add more types, and add more methods (e.g. PreparedStatement.setInt(int, int)).
