Class SingleClientConnManager

java.lang.Object
org.apache.http.impl.conn.SingleClientConnManager
All Implemented Interfaces:
ClientConnectionManager
@Contract(threading=SAFE) @Deprecated public class SingleClientConnManager extends Object implements ClientConnectionManager
Deprecated.
(4.2) use BasicClientConnectionManager
A connection manager for a single connection. This connection manager maintains only one active connection at a time. Even though this class is thread-safe it ought to be used by one execution thread only.

SingleClientConnManager will make an effort to reuse the connection for subsequent requests with the same route. It will, however, close the existing connection and open it for the given route, if the route of the persistent connection does not match that of the connection request. If the connection has been already been allocated IllegalStateException is thrown.

Since:
4.0

    • releaseConnection

      public void releaseConnection(ManagedClientConnection conn, long validDuration, TimeUnit timeUnit)
      Deprecated.
      Description copied from interface: ClientConnectionManager
      Releases a connection for use by others. You may optionally specify how long the connection is valid to be reused. Values <= 0 are considered to be valid forever.

      Specified by:
      releaseConnection in interface ClientConnectionManager
      Parameters:
      conn - the connection to release
      validDuration - the duration of time this connection is valid for reuse
      timeUnit - the unit of time validDuration is measured in
