Goods.IdentityHashtable Class
This class implements a IdentityHashtable, which maps key object to some other object. An instance of IdentityHashtable has two parameters that affect its efficiency: its capacity and its load factor. The load factor should be between 0.0 and 1.0. When the number of entries in the IdentityHashtable exceeds the product of the load factor and the current capacity, the capacity is increased by calling the rehash method. Larger load factors use memory more efficiently, at the expense of larger expected time per lookup. If many entries are to be made into a IdentityHashtable, creating it with a sufficiently large capacity may allow the entries to be inserted more efficiently than letting it perform automatic rehashing as needed to grow the table.

  Members Description  
    table The hash table data.

 
    count The total number of entries in the hash table.

 
    threshold Rehashes the table when count exceeds this threshold.

 
    loadFactor The load factor for the IdentityHashtable.

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

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

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

 
    size Returns the number of keys in this IdentityHashtable.

 
    isEmpty Tests if this IdentityHashtable maps no keys to values.

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

 
    containsKey Tests if the specified object is a key in this IdentityHashtable.

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

 
    rehash Rehashes the contents of the IdentityHashtable into a IdentityHashtable with a larger capacity. This method is called automatically when the number of keys in the IdentityHashtable exceeds this IdentityHashtable's capacity and load factor.

 
    put Maps the specified key to the specified value in this IdentityHashtable. 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 Removes the key (and its corresponding value) from this IdentityHashtable. This method does nothing if the key is not in the IdentityHashtable.

 
    clear Clears this IdentityHashtable so that it contains no keys.
