public class SaslExtensions extends Object
SaslExtensions intentionally overrides the standard equals(Object) and hashCode() methods calling their respective Object.equals(Object) and Object.hashCode() implementations. In so doing, it provides equality only via reference identity and will not base equality on the underlying values of its extentions map. The reason for this approach to equality is based off of the manner in which credentials are stored in a Subject. SaslExtensions are added to and removed from a Subject via its public credentials. The public credentials are stored in a Set in the Subject, so object equality therefore becomes a concern. With shallow, reference-based equality, distinct SaslExtensions instances with the same map values can be considered unique. This is critical to operations like token refresh.

|---|---|
static SaslExtensions | empty()Creates an "empty" instance indicating no SASL extensions. |
boolean | equals(Object o)Implements equals using the reference comparison implementation from Object.equals(Object). |
int | hashCode()Implements hashCode using the native implementation from Object.hashCode(). |
Map<String,String> | map()Returns an immutable map of the extension names and their values |
