    • Method Detail

      • getRealmIdentity

        default RealmIdentity getRealmIdentity​(Principal principal)
                                        throws RealmUnavailableException
        Get a handle for to the identity for the given principal in the context of this security realm. Any validation / name mapping is an implementation detail for the realm. The identity may or may not exist. The returned handle must be cleaned up by a call to RealmIdentity.dispose().
        Parameters:
        principal - the principal which identifies the identity within the realm (must not be null)
        Returns:
        the RealmIdentity for the provided principal (not null)
        Throws:
        RealmUnavailableException
      • getRealmIdentity

        default RealmIdentity getRealmIdentity​(Evidence evidence,
                                               Function<Principal,​Principal> principalTransformer)
                                        throws RealmUnavailableException
        Get a handle for the identity for the given evidence in the context of this security realm. Any validation / name mapping is an implementation detail for the realm. The identity may or may not exist. The principal obtained is transformed prior to obtaining the authorization identity. The returned handle must be cleaned up by a call to RealmIdentity.dispose(). Where this method is used to obtain a RealmIdentity prior to evidence verification the method RealmIdentity.getEvidenceVerifySupport(Class, String) will be used to verify if the identity is usable.
        Parameters:
        evidence - an evidence instance which identifies the identity within the realm (must not be null)
        principalTransformer - a function which defines how the principal is transformed before the authorization identity is obtained
        Returns:
        the RealmIdentity for the provided evidence (not null)
        Throws:
        RealmUnavailableException
      • getCredentialAcquireSupport

        SupportLevel getCredentialAcquireSupport​(Class<? extends Credential> credentialType,
                                                 String algorithmName,
                                                 AlgorithmParameterSpec parameterSpec)
                                          throws RealmUnavailableException
        Determine whether a credential of the given type and algorithm is definitely obtainable, possibly obtainable (for] some identities), or definitely not obtainable.
        Parameters:
        credentialType - the exact credential type (must not be null)
        algorithmName - the algorithm name, or null if any algorithm is acceptable or the credential type does not support algorithm names
        parameterSpec - the algorithm parameters to match, or null if any parameters are acceptable or the credential type does not support algorithm parameters
        Returns:
        the level of support for this credential
        Throws:
        RealmUnavailableException - if the realm is not able to handle requests for any reason
      • getEvidenceVerifySupport

        SupportLevel getEvidenceVerifySupport​(Class<? extends Evidence> evidenceType,
                                              String algorithmName)
                                       throws RealmUnavailableException
        Determine whether a given type of evidence is definitely verifiable, possibly verifiable (for some identities), or definitely not verifiable.
        Parameters:
        evidenceType - the type of evidence to be verified (must not be null)
        algorithmName - the algorithm name, or null if any algorithm is acceptable or the evidence type does not support algorithm names
        Returns:
        the level of support for this evidence type
        Throws:
        RealmUnavailableException - if the realm is not able to handle requests for any reason
      • handleRealmEvent

        default void handleRealmEvent​(RealmEvent event)
        Handle a realm event. These events allow the realm to act upon occurrences that are relevant to policy of the realm; for example, the realm may choose to increase password iteration count on authentication success, or change the salt of a password after a certain number of authentications.

        The default implementation does nothing.

        Parameters:
        event - the realm event
      • safeHandleRealmEvent

        static void safeHandleRealmEvent​(SecurityRealm realm,
                                         RealmEvent event)
        Safely pass an event to a security realm, absorbing and logging any exception that occurs.
        Parameters:
        realm - the security realm to notify (not null)
        event - the event to send (not null)
