The QuickHashStringIntHash class

はじめに

This class wraps around a hash containing strings, where the values are 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.

定義済み定数

QuickHashStringIntHash::CHECK_FOR_DUPES

If enabled, adding duplicate elements to a set (through either QuickHashStringIntHash::add or QuickHashStringIntHash::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.

QuickHashStringIntHash::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.
