GUIClientInterface

All Known Implementing Classes:

CppGUIAdapter, JavaGUIAdapter
```
public interface GUIClientInterface
```
The GUI client application can interact with any project that implements this interface. The routines listed here are not exactly those that an 802.11~ implementation is supposed to provide (see Dot11Interface for those), but have been designed for compatibility with either a C++ or Java-based implementation. If you choose to write your project in Java, you should use the JavaGUIAdapter class to implement this interface. It wraps some code around the basic 802.11~ functionality to support the routines in the interface. (Use CppGUIAdapter if you're implementing your project in C++.)

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method and Description
`short[]`	`getDefaultAddrs()` Returns an array of MAC addresses that will be assigned to buttons in the GUI client.
`int`	`initializeLinkLayer(short MACaddr)` Create an instance of the 802.11~ layer and set up the output streams.
`byte[]`	`pollForStreamOutput()` Called periodically by the GUI client to see if the 802.11~ layer has produced any output that should be displayed in the client's text window.
`int`	`sendCommand(int command, int value)` The GUI calls this when the user asks to pass command info to the 802.11~ layer.
`int`	`sendOutgoingData(short dest, byte[] payload)` Called by the GUI client when data is to be sent.
`byte[]`	`watchForIncomingData()` This is a wrapper around the 802.11~ recv() that watches for incoming packets, then prepends the srcAddr to the incoming data and returns it as a byte array.

- Method Detail
  - getDefaultAddrs
```
short[] getDefaultAddrs()
```
    Returns an array of MAC addresses that will be assigned to buttons in the GUI client.
  - initializeLinkLayer
```
int initializeLinkLayer(short MACaddr)
```
    Create an instance of the 802.11~ layer and set up the output streams.
    
    Parameters:
    
    MACaddr - The 802.11~ MAC address of this host.
    
    Returns:
    
    Result code (0 if all goes well).
  - watchForIncomingData
```
byte[] watchForIncomingData()
```
    This is a wrapper around the 802.11~ recv() that watches for incoming packets, then prepends the srcAddr to the incoming data and returns it as a byte array.
  - sendOutgoingData
```
int sendOutgoingData(short dest,
                     byte[] payload)
```
    Called by the GUI client when data is to be sent.
    
    Parameters:
    
    dest - MAC address of destination machine
    
    payload - Data to be sent
    
    Returns:
    
    Number of bytes sent
  - pollForStreamOutput
```
byte[] pollForStreamOutput()
```
    Called periodically by the GUI client to see if the 802.11~ layer has produced any output that should be displayed in the client's text window.
    
    Returns:
    
    Array of characters to be displayed
  - sendCommand
```
int sendCommand(int command,
                int value)
```
    The GUI calls this when the user asks to pass command info to the 802.11~ layer.
    
    Parameters:
    
    command - Specifies the command to send
    
    value - The value passed with the command
