protected AnonymousAuthenticationToken()

Method Detail

setAuthenticated

public void setAuthenticated(boolean isAuthenticated)

Description copied from interface: org.acegisecurity.Authentication

See Authentication.isAuthenticated()>Authentication.isAuthenticated() 55 for a full description.

Implementations should always allow this method to be called with a false parameter, as this is used by various classes to specify the authentication token should not be trusted. If an implementation wishes to reject an invocation with a true parameter (which would indicate the authentication token is trusted - a potential security risk) the implementation should throw an java.lang.IllegalArgumentException.

Specified by:

setAuthenticated in interface org.acegisecurity.Authentication

---

isAuthenticated

public boolean isAuthenticated()

Description copied from interface: org.acegisecurity.Authentication

Used to indicate to AbstractSecurityInterceptor whether it should present the authentication token to the AuthenticationManager. Typically an AuthenticationManager (or, more often, one of its AuthenticationProviders) will return an immutable authentication token after successful authentication, in which case that token can safely return true to this method. Returning true will improve performance, as calling the AuthenticationManager for every request will no longer be necessary.

For security reasons, implementations of this interface should be very careful about returning true to this method unless they are either immutable, or have some way of ensuring the properties have not been changed since original creation.

Specified by:

isAuthenticated in interface org.acegisecurity.Authentication

---

getAuthorities

public GrantedAuthority[] getAuthorities()

Description copied from interface: org.acegisecurity.Authentication

Set by an AuthenticationManager to indicate the authorities that the principal has been granted. Note that classes should not rely on this value as being valid unless it has been set by a trusted AuthenticationManager.

Specified by:

getAuthorities in interface org.acegisecurity.Authentication

---

getCredentials

public java.lang.Object getCredentials()

Always returns an empty String

Specified by:

getCredentials in interface org.acegisecurity.Authentication

---

getKeyHash

public int getKeyHash()

---

getPrincipal

public java.lang.Object getPrincipal()

Description copied from interface: org.acegisecurity.Authentication

The identity of the principal being authenticated. This is usually a username. Callers are expected to populate the principal.

Specified by:

getPrincipal in interface org.acegisecurity.Authentication

---

equals

public boolean equals(java.lang.Object obj)

Description copied from interface: java.security.Principal

This method tests another Principal object for equality with this one.

Specified by:

equals in interface java.security.Principal
