WebSocketClient

java.lang.Object
- com.dkfqs.tools.websocket.WebSocketClient

```
public class WebSocketClient
extends java.lang.Object
```
A powerful WebSocket client that supports the measurement of extended performance data to address server bottlenecks.

Response times (performance data) are measured about:
- Opening the WebSocket connection to the server (TCP/IP connect time, SSL handshake time, HTTP request time, HTTP response time).
- TCP/IP processing times for sending and receiving text frames.
- TCP/IP processing times for sending and receiving binary frames.
- TCP/IP processing times for sending and receiving ping frames.
- TCP/IP processing times for sending and receiving pong frames.
Overall summary counters (performance data) are measured at realtime about:
- The total number of sent frames
- The total sum of sent bytes - overall sent frames
- The total sum of sent payloads (in bytes) - overall sent frames
- The total number of received frames
- The total sum of received bytes - overall received frames
- The total sum of received payloads (in bytes) - overall received frames
In addition, the WebSocket client supports to monitor at realtime the number of pending frames which are awaiting to be send to the server (send frame backlog).

The WebSocket client supports to set, or rather to override, the following timeouts:
- Opening the WebSocket connection to the server timeout.
- Sending a WebSocket frame to the server timeout - report an error and close the WebSocket connection if the send timeout is exceeded.
In case if the opening a WebSocket connection to the server fails, detail error information is provided at which internal protocol level the failure has occurred.

Note for encrypted wss connections: The verification of the SSL server certificate is disabled by default. Therefore this client is also able to connect to servers which contain invalid or untrusted certificates. To override this behavior, you can set an own trust managers by using the method setTrustManagers(TrustManager[]).

Other features:
- TLS Authentication with a client certificate is supported (for example by using a certificate in PKCS#12 file-format)
- Sending WebSocket frames by using multiple threads is supported.
