- Method Detail
  - isProductionMode
```
boolean isProductionMode()
```
    Returns whether Vaadin is in production mode.
    
    Returns:
    
    true if in production mode, false otherwise.
  - isBowerMode
```
@Deprecated
boolean isBowerMode()
```
    Deprecated. Bower WebJars are being deprecated, so compatibility mode should no longer be used and will be removed in near future.
    
    Returns whether Vaadin is running in Vaadin 13 compatibility mode. NOTE: Compatibility mode is no longer supported by Flow since version 2.11. This method will throw a runtime exception when invoked.
    
    Returns:
    
    true if in compatibility mode, false otherwise.
  - isCompatibilityMode
```
@Deprecated
default boolean isCompatibilityMode()
```
    Deprecated. Bower WebJars are being deprecated, so compatibility mode should no longer be used and will be removed in near future.
    
    Returns whether Vaadin is running in Vaadin 13 compatibility mode. This method is deprecated as of version 2.11. This method will throw a runtime exception when invoked.
    
    Returns:
    
    true if in compatibility mode, false otherwise.
  - isRequestTiming
```
boolean isRequestTiming()
```
    Returns whether the server provides timing info to the client.
    
    Returns:
    
    true if timing info is provided, false otherwise.
  - isXsrfProtectionEnabled
```
boolean isXsrfProtectionEnabled()
```
    Returns whether cross-site request forgery protection is enabled.
    
    Returns:
    
    true if XSRF protection is enabled, false otherwise.
  - isSyncIdCheckEnabled
```
boolean isSyncIdCheckEnabled()
```
    Returns whether sync id checking is enabled. The sync id is used to gracefully handle situations when the client sends a message to a connector that has recently been removed on the server.
    
    Returns:
    
    true if sync id checking is enabled; false otherwise
  - getHeartbeatInterval
```
int getHeartbeatInterval()
```
    Returns the number of seconds between heartbeat requests of a UI, or a non-positive number if heartbeat is disabled.
    
    Returns:
    
    The time between heartbeats.
  - getMaxMessageSuspendTimeout
```
int getMaxMessageSuspendTimeout()
```
    In certain cases, such as when combining XmlHttpRequests and push over low bandwidth connections, messages may be received out of order by the client. This property specifies the maximum time (in milliseconds) that the client will then wait for the predecessors of a received out-order message, before considering them missing and requesting a full resynchronization of the application state from the server.
    
    Returns:
    
    The maximum message suspension timeout
  - getWebComponentDisconnect
```
int getWebComponentDisconnect()
```
    Returns the number of seconds that a WebComponent will wait for a reconnect before removing the server-side component from memory.
    
    Returns:
    
    time to wait after a disconnect has happened
  - isSendUrlsAsParameters
```
boolean isSendUrlsAsParameters()
```
    Returns whether the sending of URL's as GET and POST parameters in requests with content-type application/x-www-form-urlencoded is enabled or not.
    
    Returns:
    
    false if set to false or true otherwise
  - isCloseIdleSessions
```
boolean isCloseIdleSessions()
```
    Returns whether a Vaadin session should be closed when all its open UIs have been idle for longer than its configured maximum inactivity time.
    A UI is idle if it is open on the client side but has no activity other than heartbeat requests. If isCloseIdleSessions() == false, heartbeat requests cause the session to stay open for as long as there are open UIs on the client side. If it is true, the session is eventually closed if the open UIs do not have any user interaction.
    
    Returns:
    
    True if UIs and Vaadin sessions receiving only heartbeat requests are eventually closed; false if heartbeat requests extend UI and session lifetime indefinitely.
    
    See Also:
    
    WrappedSession.getMaxInactiveInterval()
  - getPushMode

    The push mode in use.
  - getPushURL
```
String getPushURL()
```
    Returns the URL that bidirectional ("push") client-server communication should use.
    
    Returns:
    
    The push URL to use
