	<methods>
		<method name="bind">
			<return type="int" enum="Error" />
			<param index="0" name="port" type="int" />
			<param index="1" name="host" type="String" default="&quot;*&quot;" />
			<description>
				Opens the TCP socket, and binds it to the specified local address.
				This method is generally not needed, and only used to force the subsequent call to [method connect_to_host] to use the specified [param host] and [param port] as source address. This can be desired in some NAT punchthrough techniques, or when forcing the source network interface.

		<method name="connect_to_host">
			<return type="int" enum="Error" />
			<param index="0" name="host" type="String" />
			<param index="1" name="port" type="int" />
			<description>
				Connects to the specified [code]host:port[/code] pair. A hostname will be resolved if valid. Returns [constant OK] on success.
			</description>
		</method>
		<method name="disconnect_from_host">
			<return type="void" />
			<description>
				Disconnects from host.
			</description>
		</method>
		<method name="get_connected_host" qualifiers="const">
			<return type="String" />
			<description>
				Returns the IP of this peer.
			</description>
		</method>
		<method name="get_connected_port" qualifiers="const">
			<return type="int" />
			<description>
				Returns the port of this peer.
			</description>
		</method>
		<method name="get_local_port" qualifiers="const">
			<return type="int" />
			<description>
				Returns the local port to which this peer is bound.
			</description>
		</method>
		<method name="get_status" qualifiers="const">
			<return type="int" enum="StreamPeerTCP.Status" />
			<description>
				Returns the status of the connection.
			</description>
		</method>
		<method name="poll">
			<return type="int" enum="Error" />
			<description>
				Poll the socket, updating its state. See [method get_status].
			</description>
		</method>
		<method name="set_no_delay">
			<return type="void" />
			<param index="0" name="enabled" type="bool" />
			<description>
				If [param enabled] is [code]true[/code], packets will be sent immediately. If [param enabled] is [code]false[/code] (the default), packet transfers will be delayed and combined using [url=https://en.wikipedia.org/wiki/Nagle%27s_algorithm]Nagle's algorithm[/url].
				[b]Note:[/b] It's recommended to leave this disabled for applications that send large packets or need to transfer a lot of data, as enabling this can decrease the total available bandwidth.
