# The QuickHashIntHash class

(No version information available, might only be in SVN)

## Wstęp

This class wraps around a hash containing integer numbers, where the values are also integer numbers. Hashes are also available as implementation 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.

## Stałe predefiniowane

`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.

`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.

`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.

`QuickHashIntHash::HASHER_JENKINS1`

  This is the default hashing function to turn the integer hashes into bucket list indexes.

`QuickHashIntHash::HASHER_JENKINS2`

  Selects a variant hashing algorithm.
