The default merger is MultivaluedAttributeMerger . author:    andrew.petro@yale.edu author:    Eric Dalquist edalquist@unicon.net version:    $Revision: 35515 $ $Date: 2005-04-06 08:31:40 -0700 (Wed, 06 Apr 2005) $ since:    uPortal 2.5 Method Summary public  IAttributeMerger getMerger()      Get the strategy whereby we accumulate attributes. public  List getPersonAttributeDaos()      Get the List of delegates which we will poll for attributes. public  Set getPossibleUserAttributeNames()      This implementation is not always correct. It handles the basic case where the Set of attributes returned by this implementation is the union of the attributes declared by all of the underlying implementations to be merged. public  Map getUserAttributes(Map seed)      Iterates through the configured List of IPersonAttributeDao instances. public  boolean isRecoverExceptions()      True if this class will catch exceptions thrown by its delegate DAOs and fail to propogate them. public  void setMerger(IAttributeMerger merger)      Set the strategy whereby we accumulate attributes from the results of polling our delegates. public  void setPersonAttributeDaos(List daos)      Set the List of delegates which we will poll for attributes. public  void setRecoverExceptions(boolean recover)      Set to true if you would like this class to swallow RuntimeExceptions thrown by its delegates. Method Detail getMerger public IAttributeMerger getMerger()(Code) Get the strategy whereby we accumulate attributes. Returns the attrMerger. getPersonAttributeDaos public List getPersonAttributeDaos()(Code) Get the List of delegates which we will poll for attributes. Returns the personAttributeDaos. getPossibleUserAttributeNames public Set getPossibleUserAttributeNames()(Code) This implementation is not always correct. It handles the basic case where the Set of attributes returned by this implementation is the union of the attributes declared by all of the underlying implementations to be merged. Of course, an IAttributeMerger might provide for a merging policy such that the attributes resulting from invoking this IPersonAttributeDao implementation are not the union of the attributes declared by the underlying PersonAttributeDaos. See Also:   org.jasig.portal.services.persondir.IPersonAttributeDao.getPossibleUserAttributeNames getUserAttributes public Map getUserAttributes(Map seed)(Code) Iterates through the configured List of IPersonAttributeDao instances. The results from each DAO are merged into the result Map by the configured IAttributeMerger . See Also:   org.jasig.portal.services.persondir.IPersonAttributeDao.getUserAttributes(java.util.Map) isRecoverExceptions public boolean isRecoverExceptions()(Code) True if this class will catch exceptions thrown by its delegate DAOs and fail to propogate them. False if this class will stop on failure. Returns the recoverExceptions. setMerger public void setMerger(IAttributeMerger merger)(Code) Set the strategy whereby we accumulate attributes from the results of polling our delegates. Parameters:   merger - The attrMerger to set. throws:   IllegalArgumentException - If merger is null. setPersonAttributeDaos public void setPersonAttributeDaos(List daos)(Code) Set the List of delegates which we will poll for attributes. Parameters:   daos - The personAttributeDaos to set. throws:   IllegalArgumentException - If daos is null. setRecoverExceptions public void setRecoverExceptions(boolean recover)(Code) Set to true if you would like this class to swallow RuntimeExceptions thrown by its delegates. This allows it to recover if a particular attribute source fails, still considering previous and subsequent sources. Set to false if you would like this class to fail hard upon any Throwable thrown by its children. This is desirable in cases where your Portal will not function without attributes from all of its sources. Parameters:   recover - The recoverExceptions to set.
