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

Method Detail

mergePersonAttributes

protected Map<String,List<Object>> mergePersonAttributes(Map<String,List<Object>> toModify,
                                                         Map<String,List<Object>> toConsider)

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
