can we publish an object as byte array

my question is can we publish an object as a byte array. if possible then what is the way.

i have tried this thing in this way first, i have published a byte array.
i have externalized the object and set( using api RProperty::Set()) the property as a byte array by using that externalized

object.but while geting ( using API RProperty::Get()) in the subscriber i am not able to internalize that byte array which i

have externalized. i am getting panic, system error -25 i.e unexpacted end of file when i am trying to internalisze the file.
