Constructor Detail

LongCache

public LongCache()
Constructs a new, empty hashtable. A default capacity and load factor is used. Note that the hashtable will automatically grow when it gets full.


LongCache

public LongCache(int initialCapacity)
Constructs a new, empty hashtable with the specified initial capacity.

Parameters:
initialCapacity - int the initial number of buckets
Method Detail

clear

public void clear()
Clears the hash table so that it has no more elements in it.


containsKey

public boolean containsKey(long key)
Returns true if the collection contains an element for the key.

Parameters:
key - long the key that we are looking for
Returns:
boolean

hash

public int hash(long key)
Return a hashcode for the value of the key parameter.

Parameters:
key - long
Returns:
int the hash code corresponding to the key value

put

public int put(long key,
               int value)
Puts the specified element into the hashtable, using the specified key. The element may be retrieved by doing a get() with the same key.

Parameters:
key - long the specified key in the hashtable
value - int the specified element
Returns:
int value

putIfAbsent

public int putIfAbsent(long key,
                       int value)
Puts the specified element into the hashtable, using the specified key. The element may be retrieved by doing a get() with the same key.

Parameters:
key - long the specified key in the hashtable
value - int the specified element
Returns:
int value

size

public int size()
Returns the number of elements contained in the hashtable.

Returns:
int The size of the table

toString

public java.lang.String toString()
Converts to a rather lengthy String.

Overrides:
toString in class java.lang.Object
Returns:
String the ascii representation of the receiver
