<brief_description>
Abstraction and base class for packet-based protocols.
</brief_description>
<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.

<methods>
<method name="get_available_packet_count" qualifiers="const">
<return type="int">
</return>
<description>
Return the number of packets currently available in the ring-buffer.
</description>
</method>
<method name="get_packet">
<return type="PoolByteArray">
</return>
<description>
Get a raw packet.
</description>
</method>
<method name="get_packet_error" qualifiers="const">
<return type="int" enum="Error">
</return>
<description>
Return the error state of the last packet received (via [method get_packet] and [method get_var]).
</description>
</method>
<method name="get_var">
<return type="Variant">
</return>
<argument index="0" name="allow_objects" type="bool" default="false">
</argument>
<description>
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>
</method>
<method name="put_packet">
<return type="int" enum="Error">
</return>
<argument index="0" name="buffer" type="PoolByteArray">
</argument>
<description>
Send a raw packet.
</description>
</method>
<method name="put_var">
<return type="int" enum="Error">
</return>
<argument index="0" name="var" type="Variant">
</argument>
<argument index="1" name="full_objects" type="bool" default="false">
</argument>
<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).
</description>
</method>

<members>
<member name="allow_object_decoding" type="bool" setter="set_allow_object_decoding" getter="is_object_decoding_allowed">
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].
[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).
