Class InMemoryAuthenticator

java.lang.Object

com.xdev.security.authentication.InMemoryAuthenticator

All Implemented Interfaces:

Authenticator<CredentialsUsernamePassword,Boolean>

public final class InMemoryAuthenticator
extends Object
implements Authenticator<CredentialsUsernamePassword,Boolean>

Trivial in-memory implementation of an Authenticator.

Note that this implementation stores passwords in plain text in memory and is therefor only suitable for examples or very trivial, non-security-critical use cases.
