All Implemented Interfaces:

Enclosing class:
Equivalence<T>
@Deprecated(since="2022-12-01") public static final class Equivalence.Wrapper<T> extends Object implements Serializable
Deprecated.
The Google Guava Core Libraries are deprecated and will not be part of the AEM SDK after April 2023
Wraps an object so that equals(Object) and hashCode() delegate to an Equivalence.

For example, given an Equivalence for strings named equiv that tests equivalence using their lengths: 

   
    equiv.wrap("a").equals(equiv.wrap("b")) // true
    equiv.wrap("a").equals(equiv.wrap("hello")) // false

Note in particular that an equivalence wrapper is never equal to the object it wraps. 

   
    equiv.wrap(obj).equals(obj) // always false
Since:
10.0
