TLDR

This file contains utility methods and a helper object related to serialization.

Methods

toByteArray

The toByteArray method is an extension function on the Serializable interface. It converts the object to a byte array representation by creating a ByteArrayOutputStream and writing the object to it using an ObjectOutputStream. The resulting byte array is returned.

fromByteArray

The fromByteArray method is a generic inline function that deserializes a byte array back into an object of the given type T. It takes a byte array as input and uses a ByteArrayInputStream and an ObjectInputStream to read the object from the byte array. If an exception occurs during deserialization, it logs an error message and returns null.
