How to make a ByteArray unmodified in Kotlin

Question

Is there a way to make ByteArray unmodifiable in Kotlin?

Like with collections Collections.unmodifiableList(byteList)

Answer 1

A ByteArray maps to byte[] when compiled to the JVM, and the JVM has no support for unmodifiable arrays. You can wrap a ByteArray into a class that holds the array in a property and does not provide any APIs for modifying it.
