Constructor Detail

CompositeACLVoter

public CompositeACLVoter(CurrentDetails cd,
                         BasicACLVoter basic,
                         SharingACLVoter sharing)

Method Detail

choose

public ACLVoter choose()

allowChmod

public boolean allowChmod(IObject object)

Description copied from interface: ACLVoter

test whether the given object can have its Permissions changed within the current security context.

Specified by:

allowChmod in interface ACLVoter

Parameters:

object - a model object

Returns:

if the object's permissions may be changed

allowCreation

public boolean allowCreation(IObject object)

Description copied from interface: ACLVoter

test whether the given object should be insertable into the DB. No trusted details is passed to this method, since for transient entities there are no trusted values. The SecuritySystem implementors will usually call ACLVoter.throwCreationViolation(IObject) if this method returns false.

Specified by:

allowCreation in interface ACLVoter

Parameters:

object - a non-null entity to test for creation.

Returns:

true if creation of this object can proceed

ACLEventListener.onPreInsert(org.hibernate.event.PreInsertEvent)

allowDelete

public boolean allowDelete(IObject object,
                           Details trustedDetails)

Description copied from interface: ACLVoter

test whether the given object should be deleteable given the trusted details. The details will usually be retrieved from the current state array coming from the database. The SecuritySystem implementors will usually call ACLVoter.throwDeleteViolation(IObject) if this method returns false.

Specified by:

allowDelete in interface ACLVoter

Parameters:

object - a non-null entity to test for deletion.

trustedDetails - a Details instance that is known to be valid.

Returns:

true if deletion of this object can proceed

See Also:

ACLEventListener.onPreDelete(org.hibernate.event.PreDeleteEvent)

allowLoad

public boolean allowLoad(org.hibernate.Session session,
                         java.lang.Class<? extends IObject> klass,
                         Details trustedDetails,
                         long id)

Description copied from interface: ACLVoter

test whether the object of the given Class with the given Details should be loadable in the current security context. This method does not take an actual object because that will not be generated until after loading is permitted. The SecuritySystem implementors will usually call ACLVoter.throwLoadViolation(IObject) if this method returns false.

Specified by:

allowLoad in interface ACLVoter

Parameters:

session - the Hibernate session to use for the query

klass - a non-null class to test for loading

trustedDetails - the non-null trusted details (usually from the db) for this instance

id - the id of the object which will be loaded. As opposed to the rest of the object, this must be known.

Returns:

true if loading of this object can proceed

See Also:

ACLEventListener.onPostLoad(org.hibernate.event.PostLoadEvent)

allowAnnotate

public boolean allowAnnotate(IObject object,
                             Details trustedDetails)

Description copied from interface: ACLVoter

test whether the given object should be annotatable given the trusted details. The details will usually be retrieved from the current state array coming from the database.

Specified by:

allowAnnotate in interface ACLVoter

Parameters:

object - a non-null entity to test for update.

trustedDetails - a Details instance that is known to be valid.

Returns:

true if annotation of this object can proceed

allowUpdate

public boolean allowUpdate(IObject object,
                           Details trustedDetails)

Description copied from interface: ACLVoter

test whether the given object should be updateable given the trusted details. The details will usually be retrieved from the current state array coming from the database. The SecuritySystem implementors will usually call ACLVoter.throwUpdateViolation(IObject) if this method returns false.

Specified by:

allowUpdate in interface ACLVoter

Parameters:

object - a non-null entity to test for update.

trustedDetails - a Details instance that is known to be valid.

Returns:

true if update of this object can proceed
