@TransactionType(value=NOT_SUPPORTED) public final class Byte
The Byte class is the standard wrapper for byte values.
Instances of the Byte class are not bound to any context and can be
passed between contexts without any restrictions. Objects created and returned
by the methods of this class are owned by the caller. In particular, a call to the toString()
returns a String instance bound to the owner context of the caller.
See Runtime Environment Specification for the Java Card Platform, Connected Edition, chapter 7 for details regarding transfer of ownership.
