Enumerations
------------

.. _enum_StreamPeerTCP_Status:

.. rst-class:: classref-enumeration

enum **Status**:

.. _class_StreamPeerTCP_constant_STATUS_NONE:

.. rst-class:: classref-enumeration-constant

:ref:`Status<enum_StreamPeerTCP_Status>` **STATUS_NONE** = ``0``

The initial status of the **StreamPeerTCP**. This is also the status after disconnecting.

.. _class_StreamPeerTCP_constant_STATUS_CONNECTING:

.. rst-class:: classref-enumeration-constant

:ref:`Status<enum_StreamPeerTCP_Status>` **STATUS_CONNECTING** = ``1``

A status representing a **StreamPeerTCP** that is connecting to a host.

.. _class_StreamPeerTCP_constant_STATUS_CONNECTED:

.. rst-class:: classref-enumeration-constant

:ref:`Status<enum_StreamPeerTCP_Status>` **STATUS_CONNECTED** = ``2``

A status representing a **StreamPeerTCP** that is connected to a host.

.. _class_StreamPeerTCP_constant_STATUS_ERROR:

.. rst-class:: classref-enumeration-constant

:ref:`Status<enum_StreamPeerTCP_Status>` **STATUS_ERROR** = ``3``

A status representing a **StreamPeerTCP** in error state.

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

.. _class_StreamPeerTCP_method_connect_to_host:

.. rst-class:: classref-method

: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 or :ref:`@GlobalScope.FAILED<class_@GlobalScope_constant_FAILED>` on failure.

.. rst-class:: classref-item-separator

----

.. _class_StreamPeerTCP_method_disconnect_from_host:

.. rst-class:: classref-method

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

Disconnects from host.

.. rst-class:: classref-item-separator

----

.. _class_StreamPeerTCP_method_get_connected_host:

.. rst-class:: classref-method

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

Returns the IP of this peer.

.. rst-class:: classref-item-separator

----

.. _class_StreamPeerTCP_method_get_connected_port:

.. rst-class:: classref-method

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

Returns the port of this peer.

.. rst-class:: classref-item-separator

----

.. _class_StreamPeerTCP_method_get_status:

.. rst-class:: classref-method

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

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

.. rst-class:: classref-item-separator

----

.. _class_StreamPeerTCP_method_is_connected_to_host:

.. rst-class:: classref-method

: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.

.. rst-class:: classref-item-separator

----

.. _class_StreamPeerTCP_method_set_no_delay:

.. rst-class:: classref-method

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.
