- Field Detail
  - table
```
private transient ServersHT.ServerDescEntry[] table
```
    The hash table data.
  - count
```
private transient int count
```
    The total number of entries in the hash table.
  - initialCapacity
```
private static final int initialCapacity
```
    The default initial capacity for the hashtable: 13.
    
    See Also:
    
    Constant Field Values
  - loadFactor
```
private static final float loadFactor
```
    The default load factor for the hashtable: 0.75f.
    
    See Also:
    
    Constant Field Values
  - threshold
```
private int threshold
```
    The table is rehashed each time its size exceeds this threshold.
  - KEYS
```
private static final int KEYS
```

- Constructor Detail
  - ServersHT
```
public ServersHT()
```
    Constructs a new, empty hashtable with the default initial capacity and load factor.
- Method Detail
  - size
```
public int size()
```
    Returns the number of entries in this hashtable.
    
    Returns:
    
    the number of entries in this hashtable.
  - keys
```
public Enumeration<Short> keys()
```
    Returns an enumeration of the keys (server id.) in this hashtable.
    
    Returns:
    
    an enumeration of the keys in this hashtable.
    
    See Also:
    
    Enumeration
  - elements
```
public Enumeration<ServerDesc> elements()
```
    Returns an enumeration of the server descriptors in this hashtable. Use the Enumeration methods on the returned object to fetch the elements sequentially.
    
    Returns:
    
    an enumeration of the values in this hashtable.

    Enumeration
  - get
```
public ServerDesc get(short sid)
```
    Returns the descriptor of the corresponding server.
    
    Parameters:
    
    sid - The server unique identification.
    
    Returns:
    
    the descriptor of the corresponding server.
  - rehash
```
protected void rehash()
```
    Increases the capacity of and internally reorganizes this hashtable, in order to accommodate and access its entries more efficiently. This method is called automatically when the number of keys in the hashtable exceeds this hashtable's capacity and load factor.
  - put
```
public ServerDesc put(ServerDesc desc)
```
    Maps the specified desc in this hashtable. The descriptor can be retrieved by calling the get method with a key that is equal to the server id.
    
    Parameters:
    
    desc - the descriptor.
    
    Returns:
    
    the previous value of the descriptor, or null if it did not have one.
    
    Throws:
    
    NullPointerException - if the descriptor is null.
  - remove
```
public ServerDesc remove(short sid)
```
    Removes the descriptor from this hashtable. This method does nothing if the key is not in the hashtable.
    
    Parameters:
    
    sid - the id of server that needs to be removed.
    
    Returns:
    
    the descriptor of the server or null if it is not defined.
  - clear
```
public void clear()
```
    Clears this hashtable so that it contains no descriptors.
  - toString
```
public String toString()
```
    Returns a string representation of this Hashtable object.
    
    Overrides:
    
    toString in class Object
    
    Returns:
    
    a string representation of this hashtable.
