org.gatein.sso.saml.plugin.SimpleGroup

All Implemented Interfaces:

Serializable, Cloneable, Group, Principal

public class SimpleGroup
extends SimplePrincipal
implements Group, Cloneable

Forked class because this plugin can be used on both JBoss or Tomcat and we want to be independent on AS. An implementation of Group that manages a collection of Principal objects based on their hashCode() and equals() methods. This class is not thread safe.

public SimpleGroup(String groupName)

Method Detail

addMember

public boolean addMember(Principal user)

Adds the specified member to the group.

Specified by:

addMember in interface Group

Parameters:

user - the principal to add to this group.

Returns:

true if the member was successfully added, false if the principal was already a member.

isMember

public boolean isMember(Principal member)

Returns true if the passed principal is a member of the group. This method does a recursive search, so if a principal belongs to a group which is a member of this group, true is returned. A special check is made to see if the member is an instance of org.jboss.security.AnybodyPrincipal or org.jboss.security.NobodyPrincipal since these classes do not hash to meaningful values.

Specified by:

isMember in interface Group

Parameters:

member - the principal whose membership is to be checked.

Returns:

true if the principal is a member of this group, false otherwise.

members

public Enumeration<Principal> members()

Returns an enumeration of the members in the group. The returned objects can be instances of either Principal or Group (which is a subinterface of Principal).

Specified by:

members in interface Group

Returns:

an enumeration of the group members.

removeMember

public boolean removeMember(Principal user)

Removes the specified member from the group.

Specified by:

removeMember in interface Group

Parameters:

user - the principal to remove from this group.

Returns:

true if the principal was removed, or false if the principal was not a member.

toString

public String toString()

Specified by:

toString in interface Principal

Overrides:

toString in class SimplePrincipal

clone

public Object clone()
             throws CloneNotSupportedException

Overrides:
