Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`void`	`clearOutbound()` Clear outbound queue, probably in preparation for sending destroy() to everybody.
`void`	`fail()` Notification that the socket failed.
`int`	`getListenPort()` Call after startup() to get the actual port, or -1 on startup failure.
`UDPSender`	`getSender()` The UDP sender.

`UDPPacket`	`receive()` Blocking call to receive the next inbound UDP packet from any peer.
`void`	`send(UDPPacket packet)` Add the packet to the outobund queue to be sent ASAP (as allowed by the bandwidth limiter) BLOCKING if queue is full.
`void`	`setListenPort(int newPort)` The listen port for the next socket bind.
`void`	`shutdown()` Shut down the sender, receiver, and socket.
`void`	`startup()` Caller should call getListenPort() after this to get the actual bound port and determine success .

public UDPEndpoint(RouterContext ctx,
                   UDPTransport transport,
                   int listenPort,
                   InetAddress bindAddress)
```
    Parameters:
    transport - may be null for unit testing ONLY
    listenPort - -1 or the requested port, may not be honored
    bindAddress - null ok
- Method Detail
  - clearOutbound
```
public void clearOutbound()
```
    Clear outbound queue, probably in preparation for sending destroy() to everybody.
  - fail
```
public void fail()
```
    Description copied from interface: SocketListener
    Notification that the socket failed.
    Specified by:
    fail in interface SocketListener
  - getListenPort
```
public int getListenPort()
```
    Call after startup() to get the actual port, or -1 on startup failure.
  - getSender
```
public UDPSender getSender()
```
    The UDP sender.
    Returns:
    the sender
  - isIPv4
```
public boolean isIPv4()
```
    Returns:
    true for wildcard too
  - isIPv6
```
public boolean isIPv6()
```
    Returns:
    true for wildcard too
  - receive
```
public UDPPacket receive()
```
    Blocking call to receive the next inbound UDP packet from any peer. UNIT TESTING ONLY. Direct from the socket. In normal operation, UDPReceiver thread injects to PacketHandler queue.
    Returns:
    null if we have shut down, or on failure
  - send
```
public void send(UDPPacket packet)
```
    Add the packet to the outobund queue to be sent ASAP (as allowed by the bandwidth limiter) BLOCKING if queue is full.
  - setListenPort
```
public void setListenPort(int newPort)
```
    The listen port for the next socket bind.
  - shutdown
```
public void shutdown()
```
    Shut down the sender, receiver, and socket.
  - startup
```
public void startup()
             throws SocketException
```
    Caller should call getListenPort() after this to get the actual bound port and determine success . Can be restarted.
    Throws:
    SocketException
  - toString
```
public String toString()
```
    Overrides:
    toString in class Object
