Class Hashtable

    java.lang.Object
      |
      +--org.apache.xalan.xsltc.runtime.Hashtable

public class Hashtable
extends java.lang.Object

The main hash-table implementation

Constructor Summary
`Hashtable()` Constructs a new, empty hashtable with a default capacity and load factor.
`Hashtable(int initialCapacity)` Constructs a new, empty hashtable with the specified initial capacity and default load factor.
`Hashtable(int initialCapacity, float loadFactor)` Constructs a new, empty hashtable with the specified initial capacity and the specified load factor.

Method Summary
`void` | `clear()` Clears this hashtable so that it contains no keys.
`boolean` | `contains(java.lang.Object value)` Tests if some key maps into the specified value in this hashtable.
`boolean` | `containsKey(java.lang.Object key)` Tests if the specified object is a key in this hashtable.
`java.util.Enumeration` | `elements()` Returns an enumeration of the values in this hashtable.
`java.lang.Object` | `get(java.lang.Object key)` Returns the value to which the specified key is mapped in this hashtable.
`boolean` | `isEmpty()` Tests if this hashtable maps no keys to values.
`java.util.Enumeration` | `keys()` Returns an enumeration of the keys in this hashtable.
`java.lang.Object` | `put(java.lang.Object key, java.lang.Object value)` Maps the specified `key` to the specified `value` in this hashtable.
`java.lang.Object` | `remove(java.lang.Object key)` Removes the key (and its corresponding value) from this hashtable.
`int` | `size()` Returns the number of keys in this hashtable.
`java.lang.String` | `toString()` Returns a rather long string representation of this hashtable.

Constructor Detail

### Hashtable

    public Hashtable(int initialCapacity,
                     float loadFactor)

  Constructs a new, empty hashtable with the specified initial capacity and the specified load factor.

### Hashtable

    public Hashtable(int initialCapacity)

  Constructs a new, empty hashtable with the specified initial capacity and default load factor.

### Hashtable

    public Hashtable()

  Constructs a new, empty hashtable with a default capacity and load factor.

Method Detail

### size

    public int size()

  Returns the number of keys in this hashtable.

### isEmpty

    public boolean isEmpty()

  Tests if this hashtable maps no keys to values.

### keys

    public java.util.Enumeration keys()

  Returns an enumeration of the keys in this hashtable.

### elements

    public java.util.Enumeration elements()

  Returns an enumeration of the values in this hashtable. Use the Enumeration methods on the returned object to fetch the elements sequentially.

### contains

    public boolean contains(java.lang.Object value)

  Tests if some key maps into the specified value in this hashtable. This operation is more expensive than the `containsKey` method.

### containsKey

    public boolean containsKey(java.lang.Object key)

  Tests if the specified object is a key in this hashtable.

### get

    public java.lang.Object get(java.lang.Object key)

  Returns the value to which the specified key is mapped in this hashtable.

### put

    public java.lang.Object put(java.lang.Object key,
                                java.lang.Object value)

  Maps the specified `key` to the specified `value` in this hashtable. Neither the key nor the value can be `null`.

  The value can be retrieved by calling the `get` method with a key that is equal to the original key.

### remove

    public java.lang.Object remove(java.lang.Object key)

  Removes the key (and its corresponding value) from this hashtable. This method does nothing if the key is not in the hashtable.

### clear

    public void clear()

  Clears this hashtable so that it contains no keys.

### toString

    public java.lang.String toString()

  Returns a rather long string representation of this hashtable. Handy for debugging - leave it here!!!
  Overrides:
    toString in class java.lang.Object
