- Constructor Detail
  - WebSocketStompClient
```
public WebSocketStompClient(WebSocketClient webSocketClient)
```
    Class constructor. Sets StompClientSupport.setDefaultHeartbeat(long[]) to "0,0" but will reset it back to the preferred "10000,10000" when a setTaskScheduler(org.springframework.scheduling.TaskScheduler) is configured.
    Parameters:
    webSocketClient - the WebSocket client to connect with
- Method Detail
  - getWebSocketClient
```
public WebSocketClient getWebSocketClient()
```
    Return the configured WebSocketClient.
  - setTaskScheduler
```
public void setTaskScheduler(@Nullable
                             TaskScheduler taskScheduler)
```
    Configure a scheduler to use for heartbeats and for receipt tracking.
    Note: Some transports have built-in support to work with heartbeats and therefore do not require a TaskScheduler. Receipts however, if needed, do require a TaskScheduler to be configured.
    By default, this is not set.
    Also automatically sets the defaultHeartbeat property to "10000,10000" if it is currently set to "0,0".
    Overrides:
    setTaskScheduler in class StompClientSupport
  - setInboundMessageSizeLimit
```
public void setInboundMessageSizeLimit(int inboundMessageSizeLimit)
```
    Configure the maximum size allowed for inbound STOMP message. Since a STOMP message can be received in multiple WebSocket messages, buffering may be required and this property determines the maximum buffer size per message.
    By default this is set to 64 * 1024 (64K).
  - getInboundMessageSizeLimit
```
public int getInboundMessageSizeLimit()
```
    Get the configured inbound message buffer size in bytes.
  - setAutoStartup
```
public void setAutoStartup(boolean autoStartup)
```
    Set whether to auto-start the contained WebSocketClient when the Spring context has been refreshed.
    Default is "true".
  - isAutoStartup
```
public boolean isAutoStartup()
```
    Return the value for the 'autoStartup' property. If "true", this client will automatically start and stop the contained WebSocketClient.
    Specified by:
    isAutoStartup in interface SmartLifecycle
    See Also:
    Lifecycle.start(), SmartLifecycle.getPhase(), LifecycleProcessor.onRefresh(), ConfigurableApplicationContext.refresh()
  - setPhase
```
public void setPhase(int phase)
```
    Specify the phase in which the WebSocket client should be started and subsequently closed. The startup order proceeds from lowest to highest, and the shutdown order is the reverse of that.
    By default this is Integer.MAX_VALUE meaning that the WebSocket client is started as late as possible and stopped as soon as possible.
  - getPhase
```
public int getPhase()
```
    Return the configured phase.
    Specified by:
    getPhase in interface Phased
    Specified by:
    getPhase in interface SmartLifecycle
    See Also:
    SmartLifecycle.isAutoStartup(), Lifecycle.start(), SmartLifecycle.stop(Runnable), DefaultLifecycleProcessor.getPhase(Lifecycle)
  - start
```
public void start()
```
    Description copied from interface: Lifecycle
    Start this component.
    Should not throw an exception if the component is already running.
    In the case of a container, this will propagate the start signal to all components that apply.
    Specified by:
    start in interface Lifecycle
    See Also:
    SmartLifecycle.isAutoStartup()
  - stop
```
public void stop()
```
    Description copied from interface: Lifecycle
    Stop this component, typically in a synchronous fashion, such that the component is fully stopped upon return of this method. Consider implementing SmartLifecycle and its stop(Runnable) variant when asynchronous stop behavior is necessary.
    Note that this stop notification is not guaranteed to come before destruction: On regular shutdown, Lifecycle beans will first receive a stop notification before the general destruction callbacks are being propagated; however, on hot refresh during a context's lifetime or on aborted refresh attempts, a given bean's destroy method will be called without any consideration of stop signals upfront.
    Should not throw an exception if the component is not running (not started yet).
    In the case of a container, this will propagate the stop signal to all components that apply.
    Specified by:
    stop in interface Lifecycle
    See Also:
    SmartLifecycle.stop(Runnable), DisposableBean.destroy()
  - isRunning
```
public boolean isRunning()
```
    Description copied from interface: Lifecycle
    Check whether this component is currently running.
    In the case of a container, this will return true only if all components that apply are currently running.
    Specified by:
    isRunning in interface Lifecycle
    Returns:
    whether the component is currently running
  - connect

public ListenableFuture<StompSession> connect(String url,
