This interface defines a datagram connection which knows
it's local end point address.
The protocol is transaction oriented, and delivery and duplicate
protection are not guaranteed. Applications requiring ordered
reliable delivery of streams of data should use
the SocketConnection.
A UDPDatagramConnection is returned from
Connector.open() in response to a request to
open a datagram:// URL connection string.
If the connection string omits both the host
and port fields in the URL string, then the
system will allocate an available port. The local
address and the local port can be discovered using
the accessor methods within this interface.
The syntax described here for the datagram URL connection string
is also valid for the Datagram.setAddress() method
used to assign a destination address to a Datagram
to be sent. e.g., datagram://host:port
BNF Format for Connector.open() string
The URI must conform to the BNF syntax specified below. If the URI
does not conform to this syntax, an IllegalArgumentException
is thrown.
