public class HashMapSync<K, V> extends Object implements Map<K, V>:

Object

└ HashMapSync

All Implemented Interfaces: Map

Thread-safe hash map implementation.

HashMapSync<K, V> exposes the same typed API as HashMap<K, V> and uses the hash-backed native runtime path with synchronized instance storage. Average add, lookup and remove remain O(1), with the expected lock overhead for shared mutable access. Iteration follows the hash table's internal bucket traversal and has no insertion-order guarantee.

Example

values = s:{"answer": 42}
assert values is HashMapSync<String, Int>

Constructors

Modifier and Type	Member	Description
public	HashMapSync `HashMapSync():`	Creates an empty synchronized hash map.
public	HashMapSync `HashMapSync(keys as IList<K>, values as IList<V>):`	Creates a synchronized hash map from key-value pairs.
public	HashMapSync `HashMapSync(map as Map<K, V>):`	Creates a synchronized hash map from another map.

Methods

Modifier and Type	Member	Description
public native	clear `clear() as Void`	Removes every entry.
public native	containsValue `containsValue(value as V) as Boolean`	Returns true if an entry contains the requested value.
public	get `get<R>(key as K, defaultValue as R) as R:`	Returns the associated value or a typed default when the key is absent.
public native	items `items() as IList<Tuple<K, V> >`	Returns key-value tuples as a list.
public native	keys `keys() as IList<K>`	Returns the keys as a list.
public native	remove `remove(key as K) as Boolean`	Removes an entry.
public native override	toString `toString() as String`	Returns the `s:{...}` representation of the entries.
public native	values `values() as IList<V>`	Returns the values as a list.
