# Acceptor

`class Acceptor : Acceptor<Party>`

### Constructors

<init> | `Acceptor(otherSide: Party, sessionIdForSend: Long, sessionIdForReceive: Long, progressTracker: ProgressTracker = tracker())`

### Properties

progressTracker | `val progressTracker: ProgressTracker` Override this to provide a ProgressTracker. If one is provided and stepped, the framework will do something helpful with the progress reports. If this protocol is invoked as a sub-protocol of another, then the tracker will be made a child of the current step in the parent. If its null, this protocol doesnt track progress.
topic | `val topic: String` The topic to use when communicating with other parties. If more than one topic is required then use sub-protocols. Note that this is temporary until protocol sessions are properly implemented.

### Inherited Properties

otherSide | `val otherSide: Party`
sessionIdForReceive | `val sessionIdForReceive: Long`
sessionIdForSend | `val sessionIdForSend: Long`

### Inherited Functions

call | `open fun call(): Unit` This is where you fill out your business logic.
