The QuickHashIntSet class

はじめに

This class wraps around a set containing integer numbers.

Sets 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.

クラス概要

QuickHashIntSet

class QuickHashIntSet {

/* 定数 */

const int QuickHashIntSet::CHECK_FOR_DUPES = 1;

const int QuickHashIntSet::DO_NOT_USE_ZEND_ALLOC = 2;

const int QuickHashIntSet::HASHER_NO_HASH = 256;

const int QuickHashIntSet::HASHER_JENKINS1 = 512;

const int QuickHashIntSet::HASHER_JENKINS2 = 1024;

/* メソッド */

public bool add(int $key)

public __construct(int $size, int $options = ?)

public bool delete(int $key)

public bool exists(int $key)

publicint getSize()

public static QuickHashIntSet loadFromFile(string $filename, int $size = ?, int $options = ?)

public static QuickHashIntSet loadFromString(string $contents, int $size = ?, int $options = ?)

public void saveToFile(string $filename)

public string saveToString()

}

定義済み定数

QuickHashIntSet::CHECK_FOR_DUPES: If enabled, adding duplicate elements to a set (through either QuickHashIntSet::add or QuickHashIntSet::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.
QuickHashIntSet::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.
QuickHashIntSet::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.
QuickHashIntSet::HASHER_JENKINS1: This is the default hashing function to turn the integer hashes into bucket list indexes.
QuickHashIntSet::HASHER_JENKINS2: Selects a variant hashing algorithm.

The QuickHashIntHash class

はじめに

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.
