Class ValueIdentityBiFunction<K,V>

java.lang.Object

org.keycloak.models.sessions.infinispan.stream.ValueIdentityBiFunction<K,V>

Type Parameters:

K - The type of the first argument (key). This parameter is ignored by the function.

V - The type of the second argument (value). This parameter is returned unchanged.

All Implemented Interfaces:

BiFunction<K,V,V>

@ProtoTypeId(65619)
public final class ValueIdentityBiFunction<K,V>
extends Object
implements BiFunction<K,V,V>

A BiFunction implementation that returns the second argument unchanged, effectively acting as an identity function for the value parameter.

This class is used in Infinispan cache operations where a BiFunction is required but only the value needs to be preserved without any transformation. The key parameter is ignored.

The class is implemented as a stateless singleton and is serializable via Infinispan ProtoStream to support distributed cache operations in remote caches.

Specified by:

apply in interface BiFunction<K,V,V>

Parameters:

k - The key parameter (ignored)

v - The value parameter to return

Returns:

The value parameter unchanged
