```
public class NegotiatedSettings
extends java.lang.Object
```
MQTT behavior settings that are dynamically negotiated as part of the CONNECT/CONNACK exchange. While you can infer all of these values from a combination of (1) defaults as specified in the MQTT5 spec (2) your CONNECT settings (3) the CONNACK from the broker the client instead does the combining for you and emits a NegotiatedSettings object with final, authoritative values. Negotiated settings are communicated with every successful connection establishment.

public NegotiatedSettings()
```
- Method Detail
  - getMaximumQOS
```
public QOS getMaximumQOS()
```
    Returns:
    
    Returns the maximum QoS allowed for publishes on this connection instance
  - getSessionExpiryIntervalSeconds
```
public long getSessionExpiryIntervalSeconds()
```
    Returns:
    
    Returns the amount of time in seconds the server will retain the MQTT session after a disconnect.
  - getSessionExpiryInterval
```
public long getSessionExpiryInterval()
```
    Deprecated.
    prefer getSessionExpiryIntervalSeconds instead
    
    Returns:
    
    Returns the amount of time in seconds the server will retain the MQTT session after a disconnect.
  - getReceiveMaximumFromServer
```
public int getReceiveMaximumFromServer()
```
    Returns:
    
    Returns the number of in-flight QoS 1 and QoS 2 publications the server is willing to process concurrently.
  - getMaximumPacketSizeToServer
```
public long getMaximumPacketSizeToServer()
```
    Returns:
    
    Returns the maximum packet size the server is willing to accept.
  - getTopicAliasMaximumToServer
```
public int getTopicAliasMaximumToServer()
```
    Returns:
    
    returns the maximum allowed topic alias value on publishes sent from client to server
  - getTopicAliasMaximumToClient
```
public int getTopicAliasMaximumToClient()
```
    Returns:
    
    returns the maximum allowed topic alias value on publishes sent from server to client
  - getServerKeepAliveSeconds
```
public int getServerKeepAliveSeconds()
```
    Returns the maximum amount of time in seconds between client packets. The client should use PINGREQs to ensure this limit is not breached. The server will disconnect the client for inactivity if no MQTT packet is received in a time interval equal to 1.5 x this value.
    
    Returns:
    
    The maximum amount of time in seconds between client packets.
  - getServerKeepAlive
```
public int getServerKeepAlive()
```
    Deprecated.
    prefer getServerKeepAliveSeconds
    
    Returns the maximum amount of time in seconds between client packets. The client should use PINGREQs to ensure this limit is not breached. The server will disconnect the client for inactivity if no MQTT packet is received in a time interval equal to 1.5 x this value.
    
    Returns:
    
    The maximum amount of time in seconds between client packets.
  - getRetainAvailable
```
public boolean getRetainAvailable()
```
    Returns:
    
    Returns whether the server supports retained messages.
  - getWildcardSubscriptionsAvailable
```
public boolean getWildcardSubscriptionsAvailable()
```
    Returns:
    
    Returns whether the server supports wildcard subscriptions.
  - getSubscriptionIdentifiersAvailable
```
public boolean getSubscriptionIdentifiersAvailable()
```
    Returns:
    
    Returns whether the server supports subscription identifiers
  - getSharedSubscriptionsAvailable
```
public boolean getSharedSubscriptionsAvailable()
```
    Returns:
    
    Returns whether the server supports shared subscriptions
  - getRejoinedSession
```
public boolean getRejoinedSession()
```
    Returns:
    
    Returns whether the client has rejoined an existing session.
  - getAssignedClientID
```
public java.lang.String getAssignedClientID()
```
    Returns the final client id in use by the newly-established connection. This will be the configured client id if one was given in the configuration, otherwise, if no client id was specified, this will be the client id assigned by the server. Reconnection attempts will always use the auto-assigned client id, allowing for auto-assigned session resumption.
    
    Returns:
    
    The final client id in use by the newly-established connection
