func (*Client) Close

func (xdsC *Client) Close()

Close closes the xds client.

func (*Client) InvokeWatchClusterCallback

func (xdsC *Client) InvokeWatchClusterCallback(update xdsclient.ClusterUpdate, err error)

InvokeWatchClusterCallback invokes the registered cdsWatch callback.

func (*Client) InvokeWatchEDSCallback

func (xdsC *Client) InvokeWatchEDSCallback(update xdsclient.EndpointsUpdate, err error)

InvokeWatchEDSCallback invokes the registered edsWatch callback.

func (*Client) InvokeWatchServiceCallback

func (xdsC *Client) InvokeWatchServiceCallback(u xdsclient.ServiceUpdate, err error)

InvokeWatchServiceCallback invokes the registered service watch callback.
