Enumerations

enum WriteMode:

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.

WriteMode 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:

ChannelState STATE_CONNECTING = 0

The channel was created, but it’s still trying to connect.

ChannelState STATE_OPEN = 1

The channel is currently open, and data can flow over it.

ChannelState STATE_CLOSING = 2

The channel is being closed, no new messages will be accepted, but those already in queue will be flushed.

ChannelState STATE_CLOSED = 3

The channel was closed, or connection failed.

Property Descriptions

WriteMode write_mode = 1

• void set_write_mode ( WriteMode value )

• WriteMode get_write_mode ( )

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_buffered_amount ( ) const

Returns the number of bytes currently queued to be sent over this channel.

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.

ChannelState get_ready_state ( ) const

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).

Error poll ( )

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.
