- Method Detail
  - getName
```
java.lang.String getName()
```
    Returns the name of the type of facility to which this connector can connect.
    
    Returns:
    
    connector type
  - getIcon
```
javax.swing.Icon getIcon()
```
    Returns an icon which labels this connector. The icon should preferably be 20x20 pixels. Null may be returned if you have no suitable icon.

    icon for this connector
  - getKeys

AuthKey[] getKeys()
```
    Returns an array of authorization keys whose values are required to attempt a connection. These will commonly include name and password keys, but there may be others.

  - logIn
```
Connection logIn(java.util.Map<AuthKey,?> authValues)
          throws java.io.IOException
```
    Attempts to open a connection. The supplied authValues map contains an entry for each of the keys returned by getKeys(), with the entry's value being the value for that key. Thus the values will typically be the user's name, password, etc. The values will be either String or char[] values or null (char[] may be used for hidden values for security reasons).
    
    Parameters:
    
    authValues - AuthKey->value map containing connection information
    
    Returns:
    
    a live connection object
    
    Throws:
    
    java.io.IOException - if there was some error, for instance authorization failure
