<brief_description>
TCP stream peer.
</brief_description>
<description>
TCP stream peer. This object can be used to connect to TCP servers, or also is returned by a TCP server.
[b]Note:[/b] When exporting to Android, make sure to enable the [code]INTERNET[/code] permission in the Android export preset before exporting the project or using one-click deploy. Otherwise, network communication of any kind will be blocked by Android.

<methods>
<method name="bind">
<return type="int" enum="Error" />
<argument index="0" name="port" type="int" />
<argument index="1" name="host" type="String" default=""*"" />
<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 [code]host[/code] and [code]port[/code] as source address. This can be desired in some NAT punchthrough techniques, or when forcing the source network interface.
</description>
</method>
<method name="connect_to_host">
<return type="int" enum="Error" />
<argument index="0" name="host" type="String" />
<argument 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, see [enum Status].
</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" />
<argument index="0" name="enabled" type="bool" />
<description>
If [code]enabled[/code] is [code]true[/code], packets will be sent immediately. If [code]enabled[/code] 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.
</description>
</method>
</methods>
<constants>
<constant name="STATUS_NONE" value="0" enum="Status">
The initial status of the [StreamPeerTCP]. This is also the status after disconnecting.
</constant>

A status representing a [StreamPeerTCP] that is connecting to a host.
</constant>
<constant name="STATUS_CONNECTED" value="2" enum="Status">
A status representing a [StreamPeerTCP] that is connected to a host.
</constant>
<constant name="STATUS_ERROR" value="3" enum="Status">
A status representing a [StreamPeerTCP] in error state.
