+ * - [ByteArray]
+ * - [ShortArray]
+ * - [IntArray]
+ * - [LongArray]
+ * - [FloatArray]
+ * - [DoubleArray]
+ * - [CharArray]
+ * - [UByteArray]
+ * - [UShortArray]
+ * - [UIntArray]
+ * - [ULongArray]
+ *
+ * Store with converting to primitive arrays:
+ * - [Array][Array]`<`[Boolean?][Boolean]`>`
+ * - [Array][Array]`<`[Byte?][Byte]`>`
+ * - [Array][Array]`<`[Short?][Short]`>`
+ * - [Array][Array]`<`[Int?][Int]`>`
+ * - [Array][Array]`<`[Long?][Long]`>`
+ * - [Array][Array]`<`[Float?][Float]`>`
+ * - [Array][Array]`<`[Double?][Double]`>`
+ * - [Array][Array]`<`[Char?][Char]`>`

+ *
+ * Yes, as you can see, also nullable types are supported. The values are stored in primitive arrays,
+ * and a separate set is used to store the indices of the null values.
+ *
+ * Since, [ColumnDataHolder] can be used as a [List], this is invisible to the user.
+ *
+ * @param T the type of the elements in the column
+ * @param list a [PrimitiveArrayList] or any other [MutableList] that can store the elements
+ * @param zeroValue When [list] is a [PrimitiveArrayList], this is the zero value for the primitive type
+ * @param nullIndices a set of indices where the null values are stored, only used if [list] is a [PrimitiveArrayList]
