<brief_description>
DTLS packet peer.
</brief_description>
<description>
This class represents a DTLS peer connection. It can be used to connect to a DTLS server, and is returned by [method DTLSServer.take_connection].

<description>
Connects a [code]peer[/code] beginning the DTLS handshake using the underlying [PacketPeerUDP] which must be connected (see [method PacketPeerUDP.connect_to_host]). If [code]validate_certs[/code] is [code]true[/code], [PacketPeerDTLS] will validate that the certificate presented by the remote peer and match it with the [code]for_hostname[/code] argument. You can specify a custom [X509Certificate] to use for validation via the [code]valid_certificate[/code] argument.
</description>
</method>
<method name="disconnect_from_peer">
<return type="void">
</return>
<description>
Disconnects this peer, terminating the DTLS session.
</description>
</method>
<method name="get_status" qualifiers="const">
<return type="int" enum="PacketPeerDTLS.Status">
</return>
<description>
Returns the status of the connection. See [enum Status] for values.
</description>
</method>
<method name="poll">
<return type="void">
</return>
<description>
Poll the connection to check for incoming packets. Call this frequently to update the status and keep the connection working.
</description>
</method>
</methods>
<constants>
<constant name="STATUS_DISCONNECTED" value="0" enum="Status">
A status representing a [PacketPeerDTLS] that is disconnected.

<constant name="STATUS_HANDSHAKING" value="1" enum="Status">
A status representing a [PacketPeerDTLS] that is currently performing the handshake with a remote peer.
</constant>
<constant name="STATUS_CONNECTED" value="2" enum="Status">
A status representing a [PacketPeerDTLS] that is connected to a remote peer.
</constant>
<constant name="STATUS_ERROR" value="3" enum="Status">
