ApiProviderMap

public interface ApiProviderMap<K, V>

A fast thread-safe copy-on-write map meant to be used as the backing storage for registered providers. See ApiLookupMap for a usage example.

Note: This map allows very fast lock-free concurrent reads, but in exchange writes are very expensive and should not be too frequent. Also, keys are compared by reference ({@code ==}) and not using equals.

Parameters

<K>

The key type of the map, compared by reference ({@code ==}).

<V>

The value type of the map.

Functions

create

static ApiProviderMap<K, V> create<K, V>()

Create a new instance.

get

@Nullable()

abstract V get(K key)

Return the provider to which the specified key is mapped,or {@code null} if this map contains no mapping for the key.

putIfAbsent

abstract V putIfAbsent(K key, V provider)

If the specified key is not already associated with a provider,associate it with the given value and return {@code null}, else return the current value.
