- Method Detail
  - setClientId
```
void setClientId(@NotNull String clientId)
```
    Set the client ID.
    In case the client ID is changed, future interceptors may be called by a different thread for the same client. Extensions need to ensure thread-safety for shared objects in this case. Interceptors are still called in the same order for the client.
    The client ID provided by the ClientInformation in the ConnectInboundInput is not updated until all ConnectInboundInterceptor for this CONNECT are finished.
    
    Parameters:
    
    clientId - The new client ID of the CONNECT.
    
    Throws:
    
    IllegalArgumentException - If the client ID is not a valid UTF-8 string.
    
    IllegalArgumentException - If the client ID exceeds the maximum client ID length.
    
    IllegalArgumentException - If the client ID is empty.

  - setCleanStart
```
void setCleanStart(boolean cleanStart)
```
    Set the clean start flag.
    For an MQTT 3 client clean start has the same value as clean session by default. However this MQTT 5 property can be used in the same way as for MQTT 5 client via this method.
    
    Parameters:
    
    cleanStart - The new clean start flag of the CONNECT.
    
    Since:
    
    4.2.0, CE 2020.1
  - setWillPublish
```
void setWillPublish(@Nullable WillPublishPacket willPublish)
```
    Set the will publish.
    Use Builders.willPublish() to get the WillPublishBuilder to create a will publish. To remove a will publish set this to null.
    To modify the existing WillPublishPacket use getModifiableWillPublish().
    
    Parameters:
    
    willPublish - The new will publish for the CONNECT.
    
    Since:
    
    4.2.0, CE 2020.1
  - setSessionExpiryInterval
```
void setSessionExpiryInterval(long expiryInterval)
```
    Set the expiry interval.
    For an MQTT 3 client the expiry will be 0 by default if clean session is false. This method may be used to set a custom session expiry for MQTT 3 clients.
    
    Parameters:
    
    expiryInterval - The new expiry interval for the CONNECT.
    
    Throws:
    
    IllegalArgumentException - If the expiry interval is more than the configured maximum.
    
    Since:
    
    4.2.0, CE 2020.1
  - setKeepAlive
```
void setKeepAlive(int keepAlive)
```
    Set the keep alive.
    
    Parameters:
    
    keepAlive - The new keep alive for the CONNECT.
    
    Throws:
    
    IllegalArgumentException - If the keep alive is more than the configured maximum.
    
    Since:
    
    4.2.0, CE 2020.1
  - setReceiveMaximum
```
void setReceiveMaximum(int receiveMaximum)
```
    Set the receive maximum.
    
    Parameters:
    
    receiveMaximum - The new receive maximum for the CONNECT.
    
    Throws:
    
    IllegalArgumentException - If the receive maximum is less than one or more than '65535'.
    
    Since:
    
    4.2.0, CE 2020.1
  - setMaximumPacketSize
```
void setMaximumPacketSize(int maximumPacketSize)
```
    Set the maximum packet size.
    
    Parameters:
    
    maximumPacketSize - The new maximum packet size for the CONNECT.
