getConnectionMethod

@NonNull
public ConnectionMethod getConnectionMethod()

Description copied from class: DataTransport

Returns a ConnectionMethod instance that can be used to connect to this transport.

This is used for listening transports where the address to listen on is not known until the connection has been set up for example if dynamic TCP port assignments are used or cloud relays.

For most data transports this will return the same ConnectionMethod instance that was passed at construction time. However for some transports where the address to listen on is not known until the connection have been set up (for example dynamic TCP listening port assignments or when a cloud relay is in use) it will differ.

This cannot be called until the DataTransport.Listener.onConnectionMethodReady() callback has been fired.

Specified by:

getConnectionMethod in class DataTransport

Returns:

A ConnectionMethod-derived instance.
