## Class AsyncClientEndpoint

- java.lang.Object
- - org.apache.hc.core5.http.nio.AsyncClientEndpoint

-     @Contract(threading=SAFE)
      public abstract class AsyncClientEndpoint
      extends Object

  Client endpoint leased from a connection manager.

  Once the endpoint is no longer needed it MUST be released with `releaseAndReuse()` or `releaseAndDiscard()`.

  Since:
    5.0
