# Class TransportService.ListenKey

java.lang.Object
com.sun.jdi.connect.spi.TransportService.ListenKey

Enclosing class:
  `TransportService`

public abstract static class TransportService.ListenKey extends Object
A listen key.

A `TransportService` may listen on multiple, yet different, addresses at the same time. To uniquely identify each `listener` a listen key is created each time that `startListening` is called. The listen key is used in calls to the `accept` method to accept inbound connections to that listener. A listen key is valid until it is used as an argument to `stopListening` to stop the transport service from listening on an address.
