Tests whether this bitset is known to have a finite size.
All strict collections are known to have finite size. For a non-strict collection
such as Stream
, the predicate returns true
if all elements have been computed.
It returns false
if the stream is not yet evaluated to the end.

Returns a hash code value for the object
Returns a hash code value for the object.
The default hashing algorithm is platform dependent.
Note that it is allowed for two objects to have identical hash
codes (o1.hashCode.equals(o2.hashCode)
) yet not be
equal (o1.equals(o2)
returns false
). A
degenerate implementation could always return 0
.
However, it is required that if two objects are equal
(o1.equals(o2)
returns true
) that they
have identical hash codes
(o1.hashCode.equals(o2.hashCode)
). Therefore, when
overriding this method, be sure to verify that the behavior is
consistent with the equals
method.

Converts this bitset to a list
Converts this bitset to a map
Converts this bitset to a map. This method is unavailable unless the elements are members of Tuple2, each ((K, V)) becoming a key-value pair in the map. Duplicate keys will be overwritten by later keys: if this is an unordered collection, which key is in the resulting map is undefined.

Creates a non-strict view of a slice of this bitset
Creates a non-strict view of a slice of this bitset.

is that view
produces
a view of the current bitset, whereas slice
produces a new bitset.

is equivalent to view.slice(from, to)

Creates a non-strict view of this bitset.
Creates a non-strict filter of this bitset
Creates a non-strict filter of this bitset.
Note: the difference between c filter p
and c withFilter p
is that
the former creates a new collection, whereas the latter only restricts
the domain of subsequent map

, and withFilter
operations.
Note: might return different results for different runs, unless the underlying collection type is ordered.
