### setHold

    public void setHold(int hold)

  Specifies the maximum number of requests the connection manager is allowed to keep waiting at any one time during the session.

In this case the client SHOULD inform the server by setting the values of the 'wait' and/or 'hold' attributes in its session creation request to "0", and then "poll" the server at regular intervals throughout the session for stanzas it may have received from the server.

  Returns:
    true if this session is a polling session.

  Returns the time, in seconds, after which this session will be considered inactive and terminated.

  Returns:
    the time, in seconds, after which this session will be considered inactive and terminated.

### pause

    public void pause(int duration)

  Pauses the session for the given amount of time. If a client encounters an exceptional temporary situation during which it will be unable to send requests to the connection manager for a period of time greater than the maximum inactivity period, then the client MAY request a temporary increase to the maximum inactivity period by including a 'pause' attribute in a request.

  Parameters:
    `duration` - the time, in seconds, after which this session will be considered inactive and terminated.

### getLastActivity

    public long getLastActivity()

  Returns the time in milliseconds since the epoch that this session was last active. Activity is a request was either made or responded to. If the session is currently active, meaning there are connections awaiting a response, the current time is returned.

  Returns:
    the time in milliseconds since the epoch that this session was last active.

### getLastAcknowledged

    public long getLastAcknowledged()

  Returns the highest 'rid' attribute the server has received where it has also received all requests with lower 'rid' values. When responding to a request that it has been holding, if the server finds it has already received another request with a higher 'rid' attribute (typically while it was holding the first request), then it MAY acknowledge the reception to the client.

  Returns:
    the highest 'rid' attribute the server has received where it has also received all requests with lower 'rid' values.

### setMajorVersion

    public void setMajorVersion(int majorVersion)

  Sets the major version of BOSH which the client implements. Currently, the only versions supported by Openfire are 1.5 and 1.6.

  Parameters:
    `majorVersion` - the major version of BOSH which the client implements.

### getMajorVersion

    public int getMajorVersion()

  Returns the major version of BOSH which this session utilizes. The version refers to the version of the XEP which the connecting client implements. If the client did not specify a version 1 is returned as 1.5 is the last version of the XEP that the client was not required to pass along its version information when creating a session.

  Returns:
    the major version of the BOSH XEP which the client is utilizing.

### setMinorVersion

    public void setMinorVersion(int minorVersion)

  Sets the minor version of BOSH which the client implements. Currently, the only versions supported by Openfire are 1.5 and 1.6. Any versions less than or equal to 5 will be interpreted as 5 and any values greater than or equal to 6 will be interpreted as 6.

  Parameters:
    `minorVersion` - the minor version of BOSH which the client implements.

### getMinorVersion

    public int getMinorVersion()

  Returns the major version of BOSH which this session utilizes. The version refers to the version of the XEP which the connecting client implements. If the client did not specify a version 5 is returned as 1.5 is the last version of the XEP that the client was not required to pass along its version information when creating a session.

  Returns:
    the minor version of the BOSH XEP which the client is utilizing.

### setLastResponseEmpty

    public void setLastResponseEmpty(boolean lastResponseEmpty)

  lastResponseEmpty true if last response of this session is an empty body element. This is used in overactivity checking.

  Parameters:
    `lastResponseEmpty` - true if last response of this session is an empty body element.

### consumeResponse

    protected String consumeResponse(HttpConnection connection)
                              throws HttpBindException

  Returns the response for a specific connection instance. It is possible for there to be multiple connections in the queue for the same rid so we need to be careful that we are accessing the correct connection.

  Note that this method also removes the connection from the internal connection queue.

  Parameters:
    `connection` - the connection for which to get the response.
  Returns:
    the response from the connection
  Throws:
    `HttpBindException`

### setSecure

    protected void setSecure(boolean isSecure)

  Sets whether the initial request on the session was secure.

  Parameters:
    `isSecure` - true if the initial request was secure and false if it wasn't.

### sendPendingPackets

    protected void sendPendingPackets()

  This methods sends any pending packets in the session. If no packets are pending, this method simply returns. The method is internally synchronized to avoid simultaneous sending operations on this Session. If two threads try to run this method simultaneously, the first one will trigger the pending packets to be sent, while the second one will simply return (as there are no packets left to send).

### getPeerCertificates

    public X509Certificate[] getPeerCertificates()

  Return the X509Certificates associated with this session.

  Returns:
    the X509Certificate associated with this session.

### deliver

    public void deliver(org.xmpp.packet.Packet stanza)

  Overrides:
    `deliver` in class `LocalClientSession`
