NetworkHandler

java.lang.Object
- nxt.peer.NetworkHandler

All Implemented Interfaces:

java.lang.Runnable
```
public final class NetworkHandler
extends java.lang.Object
implements java.lang.Runnable
```
The network handler creates outbound connections and adds them to the network selector. A new outbound connection will be created whenever the number of outbound connections is less than the maximum number of outbound connections. The network handler opens a local port and listens for incoming connections. When a connection is received, it creates a socket channel and accepts the connection as long as the maximum number of inbound connections has not been reached. The socket is then added to the network selector. When a message is received from a peer node, it is processed by a message handler executing on a separate thread. The message handler processes the message and then creates a response message to be returned to the originating node. The network handler terminates when its shutdown() method is called.
