selenium.webdriver.common._bidi.transport

The command seam between the generated BiDi protocol layer and the websocket.

Hand-written (not generated). Transport serializes a command’s params, sends them over the session websocket, parses the reply into its declared result type, and exposes the underlying connection for event subscription.

This is internal, unsupported implementation. See https://www.selenium.dev/documentation/warnings/bidi-implementation/

Classes

Transport(connection)

Serializes params, sends over a websocket connection, parses the reply.

class Transport(connection)

Bases: object

Serializes params, sends over a websocket connection, parses the reply.

Deliberately narrow: it holds only an immutable connection reference (the id counter and callbacks live on the shared WebSocketConnection). Each domain wraps the session’s connection in its own Transport; all the state that matters lives on the shared connection, so those transports are equivalent.

Parameters:

connection (Any)

property connection: Any

The underlying websocket, for event subscription (which lives on it, not here).

execute(cmd, params=None, result=None)

Parameters:

• cmd (str)

• params (Any | None)

• result (Any | None)

Return type:

Any
