Method Detail

createAclEntries

public void createAclEntries()

A user that has created a object, will always get READ, WRITE and DELETE permissions on that object. This can be overwritten in a subclass.

deleteAclEntries

public void deleteAclEntries()

When a user deleted an object, we will always delete the READ, WRITE and DELETE permissions on that object. If one of those permissions should not exist, nothing will happen as AclUtil.deletePermission(PersistentObject, User, org.springframework.security.acls.model.Permission) will first check if such a permission exists. This can be overwritten in a subclass.

updateAclEntries

public abstract void updateAclEntries()

Abstract method, that has to be implemented in subclasses.
