toByteArray()
is the existence of the NativeMemoryData.
With the NativeMemoryData it would lead to a temporary byte-array. This method prevents this temporary byte-array needing
to be created.dest
- to byte-buffer to write todestPos
- the position in the destination buffer.int dataSize()

during serialization.
If partition hash is not set then standard hashCode() is used.PartitionAware
