HTTPConnectionStatisticElement

java.lang.Object
- com.dkfqs.tools.http.HTTPConnectionStatisticElement

All Implemented Interfaces:

java.lang.Comparable<HTTPConnectionStatisticElement>
```
public class HTTPConnectionStatisticElement
extends java.lang.Object
implements java.lang.Comparable<HTTPConnectionStatisticElement>
```
An element of the HTTPConnectionStatistic which contains measured performance statistics about the SSL prepare time (at client side), the TCP/IP connect time and the SSL handshake time for a particular Web server key = "<protocol> + '|' + <host> + '|' + <port>".

In addition, the number of new created network connections and the number of reused network connections is also measured, which supports to calculate the efficiency of HTTP keep-alive network connections.

All methods - expect mergeElement(..) - are thread-safe.
