Enumerations

enum WriteMode:

  • WRITE_MODE_TEXT = 0 —- Tells the channel to send data over this channel as text. An external peer (non-Godot) would receive this as a string.

  • WRITE_MODE_BINARY = 1 —- Tells the channel to send data over this channel as binary. An external peer (non-Godot) would receive this as array buffer or blob.

enum ChannelState:

  • STATE_CONNECTING = 0 —- The channel was created, but it’s still trying to connect.

  • STATE_OPEN = 1 —- The channel is currently open, and data can flow over it.

  • STATE_CLOSING = 2 —- The channel is being closed, no new messages will be accepted, but those already in queue will be flushed.

  • STATE_CLOSED = 3 —- The channel was closed, or connection failed.

The transfer mode to use when sending outgoing packet. Either text or binary.

Method Descriptions

  • void close ( )

Closes this data channel, notifying the other peer.

  • int get_id ( ) const

Returns the id assigned to this channel during creation (or auto-assigned during negotiation).

If the channel is not negotiated out-of-band the id will only be available after the connection is established (will return 65535 until then).

Returns the label assigned to this channel during creation.

  • int get_max_packet_life_time ( ) const

Returns the maxPacketLifeTime value assigned to this channel during creation.

Will be 65535 if not specified.

  • int get_max_retransmits ( ) const

Returns the maxRetransmits value assigned to this channel during creation.

Will be 65535 if not specified.

  • String get_protocol ( ) const

Returns the sub-protocol assigned to this channel during creation. An empty string if not specified.

Returns the current state of this channel, see ChannelState.

  • bool is_negotiated ( ) const

Returns true if this channel was created with out-of-band configuration.

  • bool is_ordered ( ) const

Returns true if this channel was created with ordering enabled (default).

Reserved, but not used for now.

  • bool was_string_packet ( ) const

Returns true if the last received packet was transferred as text. See write_mode.
