Class PrincipalManagerImpl

java.lang.Object
  org.apache.jackrabbit.core.security.principal.PrincipalManagerImpl

All Implemented Interfaces:

PrincipalManager

public class PrincipalManagerImpl
extends Object
implements PrincipalManager

This principal manager implementation uses the DefaultPrincipalProvider in order to dispatch the respective requests and assemble the required data. It is bound to a session and therefore obliges the access restrictions of the respective subject.

Constructor Summary

PrincipalManagerImpl(Session session, PrincipalProvider[] providers)
Creates a new default principal manager implementation.

Method Summary

PrincipalIterator	findPrincipals(String simpleFilter) Gets the principals matching a simple filter expression applied against the principal name.
PrincipalIterator	findPrincipals(String simpleFilter, int searchType) Gets the principals matching a simple filter expression applied against the principal name AND the specified search type.
Principal	getEveryone() Returns the Principal which is implicitly applied to every subject.
PrincipalIterator	getGroupMembership(Principal principal) Returns an iterator over all group principals for which the given principal is either direct or indirect member of.
Principal	getPrincipal(String principalName) Returns the principal with the given name if is known to this manager (with respect to the sessions access rights).
PrincipalIterator	getPrincipals(int searchType) Returns all Principals matching the specified search type.
boolean	hasPrincipal(String principalName) Checks if the principal with the given name is known to this manager (in respect to the sessions access rights).

Constructor Detail

PrincipalManagerImpl

public PrincipalManagerImpl(Session session,
                            PrincipalProvider[] providers)

Creates a new default principal manager implementation.

Parameters:

session - the underlying session

providers - the providers

Method Detail

hasPrincipal

public boolean hasPrincipal(String principalName)

Checks if the principal with the given name is known to this manager (in respect to the sessions access rights). If this method returns true then the following expression evaluates to true as well: PrincipalManager.getPrincipal(name).getName().equals(name)

Specified by:

hasPrincipal in interface PrincipalManager

Parameters:

principalName - the name of the principal to check

Returns:

return true if the principal with this name is known to this manager; false otherwise.

getPrincipal

public Principal getPrincipal(String principalName)

Returns the principal with the given name if is known to this manager (with respect to the sessions access rights). Please note that due to security reasons Group principals will only reveal those members that are visible to the Session this PrincipalManager has been built for.

Specified by:

getPrincipal in interface PrincipalManager

Parameters:

principalName - the name of the principal to retrieve

Returns:

return the requested principal or null if not exists

findPrincipals

public PrincipalIterator findPrincipals(String simpleFilter)

Gets the principals matching a simple filter expression applied against the principal name. TODO: define the filter expression.
An implementation may limit the number of principals returned. If there are no matching principals, an empty iterator is returned.

Specified by:

findPrincipals in interface PrincipalManager

Returns:

a PrincipalIterator over the Principals matching the given filter.

findPrincipals

public PrincipalIterator findPrincipals(String simpleFilter,
                                        int searchType)

Gets the principals matching a simple filter expression applied against the principal name AND the specified search type. TODO: define the filter expression.
An implementation may limit the number of principals returned. If there are no matching principals, an empty iterator is returned.

Specified by:

findPrincipals in interface PrincipalManager

searchType - Any of the following constants:

• PrincipalManager.SEARCH_TYPE_ALL
• PrincipalManager.SEARCH_TYPE_GROUP
• PrincipalManager.SEARCH_TYPE_NOT_GROUP

Returns:

a PrincipalIterator over the Principals matching the given filter and search type.

getPrincipals

public PrincipalIterator getPrincipals(int searchType)

Returns all Principals matching the specified search type.

Specified by:

getPrincipals in interface PrincipalManager

Parameters:

searchType -

Returns:

a PrincipalIterator over all the Principals matching the given search type.

getGroupMembership

public PrincipalIterator getGroupMembership(Principal principal)

Returns an iterator over all group principals for which the given principal is either direct or indirect member of.

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

Specified by:

getGroupMembership in interface PrincipalManager

Parameters:

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

Returns:

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

getEveryone

public Principal getEveryone()

Returns the Principal which is implicitly applied to every subject.

Specified by:

getEveryone in interface PrincipalManager

Returns:

the 'everyone' principal
