NioSender (Apache Tomcat 8.0.15 API Documentation)

java.lang.Object
- org.apache.catalina.tribes.transport.AbstractSender
- - org.apache.catalina.tribes.transport.nio.NioSender

All Implemented Interfaces:

DataSender
```
public class NioSender
extends AbstractSender
```
This class is NOT thread safe and should never be used with more than one thread at a time This is a state machine, handled by the process method States are: - NOT_CONNECTED -> connect() -> CONNECTED - CONNECTED -> setMessage() -> READY TO WRITE - READY_TO_WRITE -> write() -> READY TO WRITE | READY TO READ - READY_TO_READ -> read() -> READY_TO_READ | TRANSFER_COMPLETE - TRANSFER_COMPLETE -> CONNECTED

Version:

1.0
