case object HashOnly extends Hints with Product with Serializable
A special hint telling that the internal representation should always be
hash-based as opposite to Array
. This is meaningful if the average size
of the
ArraySet
is above the limit an Array
representation is more efficient.

- val hashTableThreshold: Int
The internal representation of the adjacency list switches to a hash table when the number of edges at a given node exceeds this value.
The internal representation of the adjacency list switches to a hash table when the number of edges at a given node exceeds this value. If both
initialCapacity
andcapacityIncrement
and this value are set to0
a solely hash table representation will be used irrespective of the setsize
. This value should be close to thesize
limit anArray
representation is more efficient on the JVM with regard to looking up a given element based on==
as opposite tohashCode
. Varying with JVM implementations/configurations this limit may come in somewhere between 10 and 30. - val initialCapacity: Int
