MutableReactiveMap

A mutable map that also a StateFlow via asStateFlow, allowing for reactive observation of its contents.

It delegates MutableMap functionality to an internal map and emits an immutable Map snapshot to its collectors whenever the map is modified.

The type of keys in the map.

The type of values in the map.

Properties

abstract override val keys: MutableSet<K>

abstract val size: Int

abstract override val values: MutableCollection<V>

abstract fun asStateFlow(): StateFlow<Map<K, V>>

Returns the collection's content as a StateFlow of an immutable collection IC type.

abstract fun batchUpdate(block: MutableMap<K, V>.() -> Unit)

Executes a block of modifications on the underlying mutable collection and notifies observers only once after the block has completed.

abstract suspend fun batchUpdateAsync(block: suspend MutableMap<K, V>.() -> Unit)

Executes a suspending block of modifications on the underlying mutable collection and notifies observers only once after the block has completed.

abstract fun clear()

abstract fun containsKey(key: K): Boolean

abstract fun containsValue(value: V): Boolean

abstract operator fun get(key: K): V?

abstract fun isEmpty(): Boolean

abstract fun put(key: K, value: V): V?

abstract fun putAll(from: Map<out K, V>)

abstract fun remove(key: K): V?

Returns a new MutableReactiveMap filled with all elements of this collection.

Creates a Flow that emits the value associated with the specified key whenever this map changes.
