SnapshotStateSet

Class

NonAndroid
public actual class SnapshotStateSet<T> : StateObject, MutableSet<T>, RandomAccess

An implementation of MutableSet that can be observed and snapshot. This is the result type created by androidx.compose.runtime.mutableStateSetOf.

Functions

public actual fun toSet(): Set<T>

Return a set containing all the elements of this set.

The set returned is immutable and returned will not change even if the content of the set is changed in the same snapshot. It also will be the same instance until the content is changed. It is not, however, guaranteed to be the same instance for the same set as adding and removing the same item from the this set might produce a different instance with the same content.

This operation is O(1) and does not involve a physically copying the set. It instead returns the underlying immutable set used internally to store the content of the set.

It is recommended to use toSet when returning the value of this set from androidx.compose.runtime.snapshotFlow.
