The QuickHashIntHash class

INTRODUCTION

	This  class wraps around a hash containing integer numbers, where the values are also integer numbers. Hashes are also available as imple-
       mentation of the ArrayAccess interface.

	Hashes can also be iterated over with foreach as the Iterator interface is implemented as well. The order of which elements  are  returned
       in is not guaranteed.

       o public int QuickHashIntHash::getSize (void  )

       o publicstatic QuickHashIntHash QuickHashIntHash::loadFromFile (string  $filename, [int	$options])

       o publicstatic QuickHashIntHash QuickHashIntHash::loadFromString (string  $contents, [int  $options])

       o public void QuickHashIntHash::saveToFile (string  $filename)

       o public string QuickHashIntHash::saveToString (void  )

       o public bool QuickHashIntHash::set (int  $key, int  $value)

       o public bool QuickHashIntHash::update (int  $key, int  $value)

PREDEFINED CONSTANTS

	      o QuickHashIntHash::CHECK_FOR_DUPES  -If	enabled,  adding duplicate elements to a set (through either add() or loadFromFile()) will
		result in those elements to be dropped from the set. This will take up extra time, so only used when it is required.

	      o QuickHashIntHash::DO_NOT_USE_ZEND_ALLOC -Disables the use of PHP's internal memory manager for internal set structures. With  this
		option enabled, internal allocations will not count towards the memory_limit settings.

	      o QuickHashIntHash::HASHER_NO_HASH  -Selects  to	not use a hashing function, but merely use a modulo to find the bucket list index.
		This is not faster than normal hashing, and gives more collisions.

	      o QuickHashIntHash::HASHER_JENKINS1 -This is the default hashing function to turn the integer hashes into bucket list indexes.

	      o QuickHashIntHash::HASHER_JENKINS2 -Selects a variant hashing algorithm.
