IntToIntHashMap
public class IntToIntHashMap implements Serializable(Code)
A hash table that maps int keys to int values.
author:
   Dave Hale, Landmark Graphics
author:
   Dominique Devienne
author:
   Michael Kay: created this class based on IntHashMap



Constructor Summary
public  IntToIntHashMap()
     Initializes a map with a capacity of 8 and a load factor of 0,25.
public  IntToIntHashMap(int capacity)
     Initializes a map with the given capacity and a load factor of 0,25.
public  IntToIntHashMap(int capacity, double factor)
     Constructs a new map with initial capacity, and load factor.

The capacity is the number of keys that can be mapped without resizing the arrays in which keys and values are stored.


Method Summary
public  voidclear()
     Clears the map.
public  booleanfind(int key)
     Finds a key in the map.
public  intget(int key)
     Gets the value for this key.
public  voidput(int key, int value)
     Adds a key-value pair to the map.
public  booleanremove(int key)
     Removes a key from the map.
public  voidsetDefaultValue(int defaultValue)
    
public  intsize()
     Gets the size of the map.


Constructor Detail
IntToIntHashMap
public IntToIntHashMap()(Code)
Initializes a map with a capacity of 8 and a load factor of 0,25.



IntToIntHashMap
public IntToIntHashMap(int capacity)(Code)
Initializes a map with the given capacity and a load factor of 0,25.
Parameters:
  capacity - the initial capacity.



IntToIntHashMap
public IntToIntHashMap(int capacity, double factor)(Code)
Constructs a new map with initial capacity, and load factor.

The capacity is the number of keys that can be mapped without resizing the arrays in which keys and values are stored. For efficiency, only a fraction of the elements in those arrays are used. That fraction is the specified load factor. The initial length of the arrays equals the smallest power of two not less than the ratio capacity/factor. The capacity of the map is increased, as necessary. The maximum number of keys that can be mapped is 2^30.
Parameters:
  capacity - the initial capacity.
Parameters:
  factor - the load factor.





Method Detail
clear
public void clear()(Code)
Clears the map.



find
public boolean find(int key)(Code)
Finds a key in the map.
Parameters:
  key - Key true if the key is mapped



get
public int get(int key)(Code)
Gets the value for this key.
Parameters:
  key - Key the value, null if not found.



put
public void put(int key, int value)(Code)
Adds a key-value pair to the map.
Parameters:
  key - Key
Parameters:
  value - Value



remove
public boolean remove(int key)(Code)
Removes a key from the map.
Parameters:
  key - Key to remove true if the value was removed



setDefaultValue
public void setDefaultValue(int defaultValue)(Code)
Set the value to be returned to indicate an unused entry



size
public int size()(Code)
Gets the size of the map. the size
