        public static User fromName​(String username)
        Factory for user instances that are single string. The credentials will be added to the principal of this instance. As nothing can be said about the credentials no validation will be done.

        Will create a principal with a property "access_token" with the name as value.

        Parameters:
        token - the value for this user
        Returns:
        user instance

      • create

        public static User create​(JsonObject principal)
        Factory for user instances that are free form. The credentials will be added to the principal of this instance. As nothing can be said about the credentials no validation will be done.
        Parameters:
        principal - the free form json principal
        Returns:
        user instance

      • create

        public static User create​(JsonObject principal,
                          JsonObject attributes)
        Factory for user instances that are free form. The credentials will be added to the principal of this instance. As nothing can be said about the credentials no validation will be done.
        Parameters:
        principal - the free form json principal
        attributes - the free form json attributes that further describe the principal
        Returns:
        user instance

      • subject

        public String subject()
        The user subject. Usually a human representation that identifies this user.

        The lookup for this information will take place in several places in the following order:

        1. principal.username - Usually for username/password or webauthn authentication
        2. principal.userHandle - Optional field for webauthn
        3. attributes.idToken.sub - For OpenID Connect ID Tokens
        4. attributes.[rootClaim?]accessToken.sub - For OpenID Connect/OAuth2 Access Tokens
        Returns:
        the subject for this user or null.

      • attributes

        public JsonObject attributes()
        Gets extra attributes of the user. Attributes contain any attributes related to the outcome of authenticating a user (e.g.: issued date, metadata, etc...)
        Returns:
        a json object with any relevant attribute.

      • expired

        public boolean expired()
        Flags this user object to be expired. A User is considered expired if it contains an expiration time and the current clock time is post the expiration date.
        Returns:
        true if expired

      • expired

        public boolean expired​(int leeway)
        Flags this user object to be expired. Expiration takes 3 values in account:
        1. exp "expiration" timestamp in seconds.
        2. iat "issued at" in seconds.
        3. nbf "not before" in seconds.
        A User is considered expired if it contains any of the above and the current clock time does not agree with the parameter value. If the attributes() do not contain a key then principal() properties are checked.

        If all of the properties are not available the user will not expire.

        Implementations of this interface might relax this rule to account for a leeway to safeguard against clock drifting.

        Parameters:
        leeway - a greater than zero leeway value.
        Returns:
        true if expired

      • get

        public <T> T get​(String key)
        Get a value from the user object. This method will perform lookups on several places before returning a value.
        1. If there is a rootClaim the look up will happen in the attributes[rootClaim]
        2. If exists the value will be returned from the attributes()
        3. If exists the value will be returned from the principal()
        4. Otherwise it will be null
        Parameters:
        key - the key to look up
        Returns:
        the value or null if missing

      • getOrDefault

        public <T> T getOrDefault​(String key,
                          T defaultValue)
        Get a value from the user object. This method will perform lookups on several places before returning a value.
        1. If there is a rootClaim the look up will happen in the attributes[rootClaim]
        2. If exists the value will be returned from the attributes()
        3. If exists the value will be returned from the principal()
        4. Otherwise it will be null
        Parameters:
        key - the key to look up
        defaultValue - default value to return if missing
        Returns:
        the value or null if missing

      • containsKey

        public boolean containsKey​(String key)
        Checks if a value exists on the user object. This method will perform lookups on several places before returning.
        1. If there is a rootClaim the look up will happen in the attributes[rootClaim]
        2. If exists the value will be returned from the attributes()
        3. If exists the value will be returned from the principal()
        4. Otherwise it will be null
        Parameters:
        key - the key to look up
        Returns:
        the value or null if missing

      • authorizations

        public Authorizations authorizations()
        Returns user's authorizations that have been previously loaded by the providers.
        Returns:
        authorizations holder for the user.

      • principal

        public JsonObject principal()
        Get the underlying principal for the User. What this actually returns depends on the implementation. For a simple user/password based auth, it's likely to contain a JSON object with the following structure: 
           {
     "username", "tim"
   }
        Returns:
        JSON representation of the Principal

      • merge

        public User merge​(User other)
        Merge the principal and attributes of a second user into this object properties.

        It is important to notice that the principal merges by replacing existing keys with the new values, while the attributes (as they represent decoded data) are accumulated at the root level.

        This means that given: 

        userA = {
   attributes: {
     roles: [ 'read' ]
 }

 userB = {
   attributes: {
     roles: [ 'write' ]
   }
 }
 }

        When performing a merge of userA with userB, you will get: 

        userA.merge(userB);
 // results in
 {
   attributes: {
     roles: [ 'read', 'write' ]
 }
 }
        Parameters:
        other - the other user to merge
        Returns:
        fluent self

      • hasAmr

        public boolean hasAmr​(String value)
        The "amr" (Authentication Methods References) returns a unique list of claims as defined and registered in the IANA "JSON Web Token Claims" registry. The values in this collection are based on RFC8176. This information can be used to filter authenticated users by their authentication mechanism.
        Parameters:
        value -
        Returns:
        true if claim is present in the principal.

      • newInstance

        public static User newInstance​(User arg)
