StreamPeerTCP
=============

**Inherits:** :ref:`StreamPeer<class_StreamPeer>` **<** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`

TCP stream peer.

Description
-----------

TCP stream peer. This object can be used to connect to TCP servers, or also is returned by a TCP server.

\ **Note:** When exporting to Android, make sure to enable the ``INTERNET`` 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.

.. _class_StreamPeerTCP_constant_STATUS_NONE:

.. _class_StreamPeerTCP_constant_STATUS_CONNECTING:

.. _class_StreamPeerTCP_constant_STATUS_CONNECTED:

.. _class_StreamPeerTCP_constant_STATUS_ERROR:

enum **Status**:

- **STATUS_NONE** = **0** --- The initial status of the ``StreamPeerTCP``. This is also the status after disconnecting.

- **STATUS_CONNECTING** = **1** --- A status representing a ``StreamPeerTCP`` that is connecting to a host.

- **STATUS_CONNECTED** = **2** --- A status representing a ``StreamPeerTCP`` that is connected to a host.

- **STATUS_ERROR** = **3** --- A status representing a ``StreamPeerTCP`` in error state.

Method Descriptions
-------------------

.. _class_StreamPeerTCP_method_bind:

- :ref:`Error<enum_@GlobalScope_Error>` **bind** **(** :ref:`int<class_int>` port, :ref:`String<class_String>` host="*" **)**

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 :ref:`connect_to_host<class_StreamPeerTCP_method_connect_to_host>` to use the specified ``host`` and ``port`` as source address. This can be desired in some NAT punchthrough techniques, or when forcing the source network interface.

----

.. _class_StreamPeerTCP_method_connect_to_host:

- :ref:`Error<enum_@GlobalScope_Error>` **connect_to_host** **(** :ref:`String<class_String>` host, :ref:`int<class_int>` port **)**

Connects to the specified ``host:port`` pair. A hostname will be resolved if valid. Returns :ref:`@GlobalScope.OK<class_@GlobalScope_constant_OK>` on success.

----

.. _class_StreamPeerTCP_method_disconnect_from_host:

- void **disconnect_from_host** **(** **)**

Disconnects from host.

----

.. _class_StreamPeerTCP_method_get_connected_host:

- :ref:`String<class_String>` **get_connected_host** **(** **)** |const|

Returns the IP of this peer.

----

.. _class_StreamPeerTCP_method_get_connected_port:

- :ref:`int<class_int>` **get_connected_port** **(** **)** |const|

Returns the port of this peer.

----

.. _class_StreamPeerTCP_method_get_local_port:

- :ref:`int<class_int>` **get_local_port** **(** **)** |const|

Returns the local port to which this peer is bound.

----

.. _class_StreamPeerTCP_method_get_status:

- :ref:`Status<enum_StreamPeerTCP_Status>` **get_status** **(** **)**

Returns the status of the connection, see :ref:`Status<enum_StreamPeerTCP_Status>`.

----

.. _class_StreamPeerTCP_method_is_connected_to_host:

- :ref:`bool<class_bool>` **is_connected_to_host** **(** **)** |const|

Returns ``true`` if this peer is currently connected or is connecting to a host, ``false`` otherwise.

----

.. _class_StreamPeerTCP_method_set_no_delay:

- void **set_no_delay** **(** :ref:`bool<class_bool>` enabled **)**

If ``enabled`` is ``true``, packets will be sent immediately. If ``enabled`` is ``false`` (the default), packet transfers will be delayed and combined using `Nagle's algorithm <https://en.wikipedia.org/wiki/Nagle%27s_algorithm>`__.

\ **Note:** 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.
