MutableBitSet32

class MutableBitSet32 : MutableSet<Int>

MutableSet implementation that can store values in range 0..31.

To create an instance of this class, use one of the constructors, or the utility functions MutableBitSet32.of, MutableBitSet32.full and MutableBitSet32.empty.

Instances of this class have the following particularities:

  • Operations on a single element execute in O(1).

  • Memory usage is O(1): exactly 32 bits when unboxed.

Instances of this class are not thread-safe.

toEnumSet

inline fun <E : Enum<E>> Set<E>.toEnumSet(): Set<E>

Copies a regular Set into a set optimized for enumerations.

Depending on the enumeration size, different implementations may be returned.

Example

enum class Foo {
    A,
    B,
    C,
}

val foo = setOf(Foo.A, Foo.B).toEnumSet()

toMutableEnumSet

inline fun <E : Enum<E>> Set<E>.toMutableEnumSet(): MutableSet<E>

Copies a regular Set into a mutable set optimized for enumerations.

Depending on the enumeration size, different implementations may be returned.

Example

enum class Foo {
    A,
    B,
    C,
}

val foo = setOf(Foo.A, Foo.B).toMutableEnumSet()
