public AcmeIntHashtable(int initialCapacity)

AcmeIntHashtable

public AcmeIntHashtable()

Method Detail

size

public int size()

Description copied from class: java.util.Dictionary

Returns the number of values currently in this Dictionary.

---

isEmpty

public boolean isEmpty()

Description copied from class: java.util.Dictionary

Returns true when there are no elements in this Dictionary.

---

keys

public java.util.Enumeration keys()

Description copied from class: java.util.Dictionary

Returns an Enumeration of the keys in this Dictionary

---

elements

public java.util.Enumeration elements()

Description copied from class: java.util.Dictionary

Returns an Enumeration of the values in this Dictionary.

---

contains

public boolean contains(java.lang.Object value)

---

containsKey

public boolean containsKey(int key)

---

get

public java.lang.Object get(int key)

---

get

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

Description copied from class: java.util.Dictionary

Returns the value associated with the supplied key, or null if no such value exists. Since Dictionaries are not allowed null keys or elements, a null result always means the key is not present.

---

rehash

protected void rehash()

---

put

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

---

put

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

Description copied from class: java.util.Dictionary

Inserts a new value into this Dictionary, located by the supplied key. Dictionary does not support null keys or values, so a null return can safely be interpreted as adding a new key.

---

remove

public java.lang.Object remove(int key)

---

remove

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

Description copied from class: java.util.Dictionary

Removes from the Dictionary the value located by the given key. A null return safely means that the key was not mapped in the Dictionary.

---

clear

public void clear()

---

clone

public java.lang.Object clone()

Description copied from class: java.lang.Object

This method may be called to create a new copy of the Object. The typical behavior is as follows:

• o == o.clone() is false
• o.getClass() == o.clone().getClass() is true
• o.equals(o) is true

However, these are not strict requirements, and may be violated if necessary. Of the three requirements, the last is the most commonly violated, particularly if the subclass does not override Object.equals(Object)>Object.equals(Object) 55 .

If the Object you call clone() on does not implement java.lang.Cloneable (which is a placeholder interface), then a CloneNotSupportedException is thrown. Notice that Object does not implement Cloneable; this method exists as a convenience for subclasses that do.

Object's implementation of clone allocates space for the new Object using the correct class, without calling any constructors, and then fills in all of the new field values with the old field values. Thus, it is a shallow copy. However, subclasses are permitted to make a deep copy.

All array types implement Cloneable, and override this method as follows (it should never fail):

 public Object clone()
 {
   try
     {
       super.clone();
     }
   catch (CloneNotSupportedException e)
     {
       throw new InternalError(e.getMessage());
     }
 }
 

---

toString

public java.lang.String toString()

Description copied from class: java.lang.Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).
