Interface PrincipalProvider

All Known Implementing Classes:

CompositePrincipalProvider, EmptyPrincipalProvider

public interface PrincipalProvider

The PrincipalProvider defines methods to provide access to sources of Principals. This allows the security framework share any external sources for authorization and authentication, as may be used by a custom LoginModule for example. A single PrincipalProvider implementation is expected to exposed principals from one single source. In contrast to the PrincipalManager which will expose all known and accessible principals from possibly different sources. See also CompositePrincipalProvider for a mechanism to combine principals of different providers.

Method Summary

Modifier and Type	Method and Description
java.util.Iterator<? extends java.security.Principal>	findPrincipals(int searchType) Find all principals that match the search type.
java.util.Iterator<? extends java.security.Principal>	findPrincipals(java.lang.String nameHint, int searchType) Find the principals that match the specified nameHint and search type.
java.util.Set<java.security.acl.Group>	getGroupMembership(java.security.Principal principal) Returns an iterator over all group principals for which the given principal is either direct or indirect member of.
java.security.Principal	getPrincipal(java.lang.String principalName) Returns the principal with the specified name or null if the principal does not exist.
java.util.Set<? extends java.security.Principal>	getPrincipals(java.lang.String userID) Tries to resolve the specified userID to a valid principal and it's group membership.

Method Detail

getPrincipal

java.security.Principal getPrincipal(java.lang.String principalName)

Returns the principal with the specified name or null if the principal does not exist.

Parameters:

principalName - the name of the principal to retrieve

Returns:

return the requested principal or null

getGroupMembership

java.util.Set<java.security.acl.Group> getGroupMembership(java.security.Principal principal)

Returns an iterator over all group principals for which the given principal is either direct or indirect member of. Thus for any principal returned in the iterator Group.isMember(Principal) must return true.

Example:
If Principal is member of Group A, and Group A is member of Group B, this method will return Group A and Group B.

Parameters:

principal - the principal to return it's membership from.

Returns:

an iterator returning all groups the given principal is member of.

Group.isMember(java.security.Principal)

getPrincipals

java.util.Set<? extends java.security.Principal> getPrincipals(java.lang.String userID)

Tries to resolve the specified userID to a valid principal and it's group membership. This method returns an empty set if the specified ID cannot be resolved.

Parameters:

userID - A userID.

Returns:

The set of principals associated with the specified userID or an empty set if it cannot be resolved.

findPrincipals

java.util.Iterator<? extends java.security.Principal> findPrincipals(java.lang.String nameHint,
                                                                     int searchType)

Find the principals that match the specified nameHint and search type.

Parameters:

nameHint - A name hint to use for non-exact matching.

searchType - Limit the search to certain types of principals. Valid values are any of

• PrincipalManager.SEARCH_TYPE_ALL

• PrincipalManager.SEARCH_TYPE_NOT_GROUP

• PrincipalManager.SEARCH_TYPE_GROUP

Returns:

An iterator of principals.

findPrincipals

java.util.Iterator<? extends java.security.Principal> findPrincipals(int searchType)

Find all principals that match the search type.

Parameters:

searchType - Limit the search to certain types of principals. Valid values are any of

• PrincipalManager.SEARCH_TYPE_ALL

• PrincipalManager.SEARCH_TYPE_NOT_GROUP

• PrincipalManager.SEARCH_TYPE_GROUP

Returns:

An iterator of principals.
