Class MultivaluedAttributeMerger

java.lang.Object

org.apereo.services.persondir.support.merger.BaseAdditiveAttributeMerger

org.apereo.services.persondir.support.merger.MultivaluedAttributeMerger

All Implemented Interfaces:

IAttributeMerger

public class MultivaluedAttributeMerger
extends BaseAdditiveAttributeMerger

Merger that retains values from both maps. If a value exists for a key in both maps the following is done:

• If both maps have a List they are merged into a single List
• If one map has a List and the other a single value the value is added to the List
• If both maps have a single value a List is created from the two.

Description copied from class: BaseAdditiveAttributeMerger

Modify the "toModify" argument in consideration of the "toConsider" argument. Return the resulting Map, which may or may not be the same reference as the "toModify" argument. The modification performed is implementation-specific -- implementations of this interface exist to perform some particular transformation on the toModify argument given the toConsider argument.

Specified by:

mergePersonAttributes in class BaseAdditiveAttributeMerger

Parameters:

toModify - - modify this map

toConsider - - in consideration of this map

Returns:

the modified Map
