WebSocketPeer

Inherits: PacketPeer < Reference < Object

A class representing a specific WebSocket connection.

Description

This class represents a specific WebSocket connection, allowing you to do lower level operations with it.

You can choose to write to the socket in binary or text mode, and you can recognize the mode used for writing by the other peer.

Methods

Enumerations

enum WriteMode:

• WRITE_MODE_TEXT = 0 —- Specifies that WebSockets messages should be transferred as text payload (only valid UTF-8 is allowed).

• WRITE_MODE_BINARY = 1 —- Specifies that WebSockets messages should be transferred as binary payload (any byte combination is allowed).

Method Descriptions

• void close ( int code=1000, String reason=”” )

Closes this WebSocket connection. code is the status code for the closure (see RFC 6455 section 7.4 for a list of valid status codes). reason is the human readable reason for closing the connection (can be any UTF-8 string that’s smaller than 123 bytes).

Note: To achieve a clean close, you will need to keep polling until either WebSocketClient.connection_closed or WebSocketServer.client_disconnected is received.

Note: The HTML5 export might not support all status codes. Please refer to browser-specific documentation for more details.

• String get_connected_host ( ) const

Returns the IP address of the connected peer.

Note: Not available in the HTML5 export.

• int get_connected_port ( ) const

Returns the remote port of the connected peer.

Note: Not available in the HTML5 export.

• int get_current_outbound_buffered_amount ( ) const

Returns the current amount of data in the outbound websocket buffer. Note: HTML5 exports use WebSocket.bufferedAmount, while other platforms use an internal buffer.

• WriteMode get_write_mode ( ) const

Gets the current selected write mode. See WriteMode.

• bool is_connected_to_host ( ) const

Returns true if this peer is currently connected.

• void set_no_delay ( bool enabled )

Disable Nagle’s algorithm on the underling TCP socket (default). See StreamPeerTCP.set_no_delay for more information.

Note: Not available in the HTML5 export.

• void set_write_mode ( WriteMode mode )

Sets the socket to use the given WriteMode.

• bool was_string_packet ( ) const

Returns true if the last received packet was sent as a text payload. See WriteMode.
