Class Credential

java.lang.Object

com.allanbank.mongodb.Credential

All Implemented Interfaces:

Serializable

public final class Credential
extends Object
implements Serializable

Credential provides an immutable set of credential for accessing MongoDB.

A given client can support a different set of credential for each database the client is accessing. The client can also authenticate against the "admin" database which will apply across all databases.

Note: While we use the term user name/password within this class the values may not actually be a user name or a password. In addition not all authentication mechanisms may use all of the fields in this class. See the documentation for the authenticator being used for details on what values are expected for each of the fields in this class.
