Record Class Tuple<V1,V2>

java.lang.Object
java.lang.Record
org.jgroups.util.Tuple<V1,V2>
Type Parameters:
V1 - V1
V2 - V2
Record Components:
val1 - val1
val2 - val2
public record Tuple<V1,V2>(V1 val1, V2 val2) extends Record
Holds 2 values, useful when we have a map with a key, but more than 1 value and we don't want to create a separate holder object for the values, and don't want to pass the values as a list or array.
