方法详细资料

• getTransportTypes

  public List<TransportType> getTransportTypes()

  从接口复制的说明: Transport
  Return the SockJS transport types that this transport can be used for. In particular since from a client perspective there is no difference between XHR and XHR streaming, an XhrTransport could do both.

  指定者:

  getTransportTypes 在接口中 Transport

• setXhrStreamingDisabled

  public void setXhrStreamingDisabled​(boolean disabled)

  An XhrTransport can support both the "xhr_streaming" and "xhr" SockJS server transports. From a client perspective there is no implementation difference.

  Typically an XhrTransport is used as "XHR streaming" first and then, if that fails, as "XHR". In some cases however it may be helpful to suppress XHR streaming so that only XHR is attempted.

  By default this property is set to false which means both "XHR streaming" and "XHR" apply.

• isXhrStreamingDisabled

  public boolean isXhrStreamingDisabled()

  Whether XHR streaming is disabled or not.

  指定者:

  isXhrStreamingDisabled 在接口中 XhrTransport
