Class Tuple

java.lang.Object

com.couchbase.client.core.lang.Tuple

public final class Tuple
extends java.lang.Object

Static factory class for various Tuples.

A tuple should be used if more than one argument needs to be passed through a observable. Note that there are intentionally only tuples with a maximum of five elements, because if more are needed it hurts readability and value objects should be used instead. Also keep in mind that if a tuple is used instead of a value object semantics might get lost, so use them sparingly.
