	<description>
		PacketPeer is an abstraction and base class for packet-based protocols (such as UDP). It provides an API for sending and receiving packets both as raw data or variables. This makes it easy to transfer data over a protocol, without having to encode data as low level bytes or having to worry about network ordering.

				Get a Variant. When [code]allow_objects[/code] (or [member allow_object_decoding]) is [code]true[/code] decoding objects is allowed.
				[b]WARNING:[/b] Deserialized object can contain code which gets executed. Do not use this option if the serialized object comes from untrusted sources to avoid potential security threats (remote code execution).

			<description>
				Send a raw packet.

			<description>
				Send a Variant as a packet. When [code]full_objects[/code] (or [member allow_object_decoding]) is [code]true[/code] encoding objects is allowed (and can potentially include code).

			Deprecated. Use [code]get_var[/code] and [code]put_var[/code] parameters instead.
			If [code]true[/code] the PacketPeer will allow encoding and decoding of object via [method get_var] and [method put_var].
