//*** HashTableKey_Int.cpp ***

#include "HashTableKey_Int.h"


//*** Constructor ***

HashTableKey_Int::HashTableKey_Int():
   hash_(0)
   {
   }


//*** Constructor ***

HashTableKey_Int::HashTableKey_Int(unsigned int number)
   {
   // No need for any complex calculations for this key type. Just use the number as is.
   hash_=number;
   }


//*** GetHash ***

unsigned int HashTableKey_Int::GetHash() const 
   { 
   return hash_; 
   }
   
   
//*** GetInt ***

unsigned int HashTableKey_Int::GetInt() const
   {
   return hash_;
   }

   
//*** Compare ***

bool HashTableKey_Int::Compare(const HashTableKey* key) const
   {
   // Make sure key is of the correct type
   if (key->GetType()!=GetType())
      {
      return false;

   // Since the key number and the hash are the same for this
   // sort of key, we can simply compare the hash values
   return hash_==(static_cast<const HashTableKey_Int*>(key))->hash_;
   }


//*** GetType ***

StringId HashTableKey_Int::GetType() const
   {
   static StringId type("HashTableKey_Int");
