GetKeysAsync Method

GetKeysAsync(IPredicate)

Queries the map based on the specified predicate and returns matching keys.

Declaration

Task<IReadOnlyCollection<TKey>> GetKeysAsync(IPredicate predicate)

Parameters

IPredicate

predicate

A predicate to filter the entries with.

Returns

Task<IReadOnlyCollection<TKey>>

readonly clone of all keys matching the predicate.

Remarks

Specified predicate runs on all members in parallel.

The returned collection is NOT backed by this dictionary, so changes to the dictionary are NOT reflected in the collection, and vice-versa.

The predicate must be serializable via Hazelcast serialization, and have a counterpart on the server.
