    • codecRequired

      public static boolean codecRequired(@NotNull com.illumon.dataobjects.ColumnDefinition<?> columnDefinition)
      Test whether a codec is required to write or read the supplied ColumnDefinition.
      Parameters:
      columnDefinition - The ColumnDefinition
      Returns:
      Whether a codec is required

    • codecRequired

      public static boolean codecRequired(@NotNull Class<?> dataType, @Nullable Class<?> componentType)
      Test whether a codec is required to write or read the supplied types.
      Parameters:
      dataType - The data type to check
      componentType - The component type to check, for array and DbArray types
      Returns:
      Whether a codec is required

    • explicitCodecPresent

      public static boolean explicitCodecPresent(String codecClassName)
      Test whether an explicit codec has been set.
      Parameters:
      codecClassName - The codec class name
