• ## Method Details

• ### tap

default DoubleSet tap(DoubleProcedure procedure)
Specified by:
tap in interface DoubleIterable
Since:
9.0.
• ### union

DoubleSet union(DoubleSet set)
Since:
11.0.
• ### intersect

DoubleSet intersect(DoubleSet set)
Returns the set of all objects that are members of both this and set. The intersection of [1, 2, 3] and [2, 3, 4] is the set [2, 3].
Since:
11.0.
• ### difference

DoubleSet difference(DoubleSet set)
Returns the set of all members of this that are not members of set. The difference of [1, 2, 3] and [2, 3, 4] is the set [1].
Since:
11.0.
• ### symmetricDifference

DoubleSet symmetricDifference(DoubleSet set)
Returns the set of all objects that are a member of exactly one of this and set (elements which are in one of the sets, but not in both). For instance, for the sets [1, 2, 3] and [2, 3, 4], the symmetric difference set is [1, 4] . It is the set difference of the union and the intersection.
Since:
11.0.
• ### isSubsetOf

default boolean isSubsetOf(DoubleSet set)
Returns true if all the members of this are also members of set. For example, [1, 2] is a subset of [1, 2, 3], but [1, 4] is not.
Since:
11.0.
• ### isProperSubsetOf

default boolean isProperSubsetOf(DoubleSet set)
Returns true if all the members of this are also members of set and the two sets are not equal. For example, [1, 2] is a proper subset of [1, 2, 3], but [1, 2, 3] is not.
Since:
11.0.
• ### cartesianProduct

cartesianProduct(DoubleSet set)
Returns the set whose members are all possible ordered pairs (a, b) where a is a member of this and b is a member of set.
Since:
11.0.
• ### equals

boolean equals(Object o)
Follows the same general contract as Set.equals(Object).
Overrides:
equals in class Object
• ### hashCode

int hashCode()
Follows the same general contract as Set.hashCode().
Overrides:
hashCode in class Object
• ### select

DoubleSet select(DoublePredicate predicate)
Description copied from interface: DoubleIterable
Returns a new DoubleIterable with all of the elements in the DoubleIterable that return true for the specified predicate.
Specified by:
select in interface DoubleIterable
• ### reject

DoubleSet reject(DoublePredicate predicate)
Description copied from interface: DoubleIterable
Returns a new DoubleIterable with all of the elements in the DoubleIterable that return false for the specified predicate.
Specified by:
reject in interface DoubleIterable
• ### collect

<V> SetIterable<V> collect(DoubleToObjectFunction<? extends V> function)
Description copied from interface: DoubleIterable
Returns a new collection with the results of applying the specified function on each element of the source collection. This method is also commonly called transform or map.
Specified by:
collect in interface DoubleIterable
• ### freeze

DoubleSet freeze()
Returns a frozen copy of this set. If the set is frozen, it returns itself. A frozen copy is the same thing as an immutable copy without safe-publish guarantees.
• ### toImmutable

ImmutableDoubleSet toImmutable()
Returns an immutable copy of this set. If the set is immutable, it returns itself.
