Package org.openqa.selenium.grid.node

Class Node

java.lang.Object
org.openqa.selenium.grid.node.Node
All Implemented Interfaces:
org.openqa.selenium.remote.http.HttpHandler, org.openqa.selenium.remote.http.Routable, HasReadyState
Direct Known Subclasses:
LocalNode, RemoteNode
public abstract class Node extends Object implements HasReadyState, org.openqa.selenium.remote.http.Routable
A place where individual webdriver sessions are running. Those sessions may be in-memory, or only reachable via localhost and a network. Or they could be something else entirely.

This class responds to the following URLs:

Verb URL Template Meaning
POST /se/grid/node/session Attempts to start a new session for the given node. The posted data should be a json-serialized Capabilities instance. Returns a serialized Session. Subclasses of Node are expected to register the session with the SessionMap.
GET /se/grid/node/session/{sessionId} Finds the Session identified by sessionId and returns the JSON-serialized form.
DELETE /se/grid/node/session/{sessionId} Stops the Session identified by sessionId. It is expected that this will also cause the session to removed from the SessionMap.
GET /se/grid/node/owner/{sessionId} Allows the node to be queried about whether or not it owns the Session identified by sessionId. This returns a boolean.
DELETE /se/grid/node/connection/{sessionId} Notifies the node about closure of a websocket connection for the Session identified by sessionId.
POST /se/grid/node/connection/{sessionId} Allows the node to be ask about whether or not new websocket connections are allowed for the Session identified by sessionId. This returns a boolean.
* /session/{sessionId}/* The request is forwarded to the Session identified by sessionId. When the Quit command is called, the Session should remove itself from the SessionMap.
