SocketEnginePollable

public protocol SocketEnginePollable : SocketEngineSpec

Protocol that is used to implement socket.io polling support

Properties

                invalidated
                `

true If engine’s session has been invalidated.

Swift

var invalidated: Bool { get }

                postWait
                `

A queue of engine.io messages waiting for POSTing

You should not touch this directly

Swift

var postWait: [Post] { get set }

                session
                `

The URLSession that will be used for polling.

Swift

var session: URLSession? { get }

                waitingForPoll
                `

true if there is an outstanding poll. Trying to poll before the first is done will cause socket.io to disconnect us.

Do not touch this directly

Swift

var waitingForPoll: Bool { get set }

                waitingForPost
                `
