This constructor creates a new QuickHashIntSet. 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.

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 4 to 4194304.

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