Partitions this mutable set into a map of mutable sets according to some discriminator function

Tests whether this mutable set is known to have a finite size
Tests whether this mutable set 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.
Note: many collection methods will not work on collections of infinite sizes.
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.

be available.
an array containing all elements of this mutable set.

Converts this mutable set of pairs into two collections of the first and second halfs of each pair
Converts this mutable set of pairs into two collections of the first and second halfs of each pair.
an implicit conversion which asserts that the element type of this mutable set is a pair.
a pair mutable sets, containing the first, respectively second half of each element pair of this mutable set.
Updates the presence of a single element in this set
Updates the presence of a single element in this set.
This method allows one to add or remove an element elem
from this set depending on the value of parameter included
.
Typically, one would use the following syntax:
{{{
set(elem) = true // adds element
set(elem) = false // removes element
}}}
the element to be added or removed
a flag indicating whether element should be included or excluded.
Creates a non-strict view of a slice of this mutable set
Creates a non-strict view of a slice of this mutable set.
Note: the difference between view
and slice
is that view
produces
a view of the current mutable set, whereas slice
produces a new mutable set.
Note: view(from, to)
is equivalent to view.slice(from, to)
Note: might return different results for different runs, unless the underlying collection type is ordered.
the index of the first element of the view
the index of the element following the view

Creates a non-strict view of this mutable set
Creates a non-strict view of this mutable set.
Creates a non-strict filter of this mutable set
Creates a non-strict filter of this mutable set.
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
, flatMap
, foreach
, and withFilter
operations.
Note: might return different results for different runs, unless the underlying collection type is ordered.
the predicate used to test elements.
an object of class WithFilter
, which supports
map
, flatMap
, foreach
, and withFilter
operations.
All these operations apply to those elements of this mutable set which
satify the predicate p
.
Returns a mutable set formed from this mutable set and another iterable collection by combining corresponding elements in pairs
Returns a mutable set formed from this mutable set and another iterable collection by combining corresponding elements in pairs. If one of the two collections is longer than the other, its remaining elements are ignored.
Note: might return different results for different runs, unless the underlying collection type is ordered.
the type of the first half of the returned pairs (this is always a supertype
of the collection's element type A
).
the type of the second half of the returned pairs
the class of the returned collection. Where possible, That
is
the same class as the current collection class Repr
, but this
depends on the element type (A1, B)
being admissible for that class,
which means that an implicit instance of type CanBuildFrom[Repr, (A1, B), That]

is found.
The iterable providing the second half of each result pair
an implicit value of class CanBuildFrom
which determines the
result class That
from the current representation type Repr
and the new element type (A1, B)
.
a new collection of type That
containing pairs consisting of
corresponding elements of this mutable set and that
. The length
of the returned collection is the minimum of the lengths of this mutable set$ and that
.
Returns a mutable set formed from this mutable set and another iterable collection by combining corresponding elements in pairs
Returns a mutable set formed from this mutable set and another iterable collection by combining corresponding elements in pairs. If one of the two collections is shorter than the other, placeholder elements are used to extend the shorter collection to the length of the longer.
Note: might return different results for different runs, unless the underlying collection type is ordered.
the iterable providing the second half of each result pair
the element to be used to fill up the result if this mutable set is shorter than that
.
the element to be used to fill up the result if that
is shorter than this mutable set.
a new collection of type That
containing pairs consisting of
corresponding elements of this mutable set and that
. The length
of the returned collection is the maximum of the lengths of this mutable set$ and that
.
If this mutable set is shorter than that
, thisElem
values are used to pad the result.
If that
is shorter than this mutable set, thatElem
values are used to pad the result.

Todo: this has O(n) cost for element removal. Should be rewritten to be more efficient.
