Method Detail

mergeAttributes

Map<String,List<Object>> mergeAttributes(Map<String,List<Object>> toModify,
                                         Map<String,List<Object>> toConsider)

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.

Parameters:

toModify - - modify this map

toConsider - - in consideration of this map

Returns:

the modified Map

Throws:

IllegalArgumentException - if either toModify or toConsider is null
