QuickHashIntHash::__construct

Creates a new QuickHashIntHash object

&reftitle.description; public `QuickHashIntHash::__construct` `int` `size` `int` `options`

This constructor creates a new `QuickHashIntHash`. The size is the amount of bucket lists to create. The more lists there are, the less collisions you will have. Options are also supported.

&reftitle.parameters;

`size`

- The amount of bucket lists to configure. The number you pass in will be automatically rounded up to the next power of two. It is also automatically limited from `64` to `4194304`.

`options`

- The options that you can pass in are: `QuickHashIntHash::CHECK_FOR_DUPES`, which makes sure no duplicate entries are added to the hash; `QuickHashIntHash::DO_NOT_USE_ZEND_ALLOC` to not use PHP's internal memory manager as well as one of `QuickHashIntHash::HASHER_NO_HASH`, `QuickHashIntHash::HASHER_JENKINS1` or `QuickHashIntHash::HASHER_JENKINS2`. These last three configure which hashing algorithm to use. All options can be combined using bitmasks.

&reftitle.returnvalues;

Returns a new `QuickHashIntHash` object.
