Method Summary

Modifier and Type	Method and Description
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.
Set<String>	mergeAvailableQueryAttributes(Set<String> toModify, Set<String> toConsider) Modify the "toModify" argument in consideration of the "toConsider" argument.
Set<String>	mergePossibleUserAttributeNames(Set<String> toModify, Set<String> toConsider) Modify the "toModify" argument in consideration of the "toConsider" argument.
Set<IPersonAttributes>	mergeResults(Set<IPersonAttributes> toModify, Set<IPersonAttributes> toConsider) Merge the results of a Set of IPersonAttributes and a compiled results map.

Method Detail

mergeResults

Set<IPersonAttributes> mergeResults(Set<IPersonAttributes> toModify,
                                    Set<IPersonAttributes> toConsider)

Merge the results of a Set of IPersonAttributes and a compiled results map.

Parameters:

toModify - The compiled results map, this will be modified based on the values in toConsider.

toConsider - The query results map, this will not be modified.

Returns:

Merged set of IPersonAttributes

mergePossibleUserAttributeNames

Set<String> mergePossibleUserAttributeNames(Set<String> toModify,
                                            Set<String> toConsider)

Modify the "toModify" argument in consideration of the "toConsider" argument. Return the resulting Set 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 set

toConsider - In consideration of this set

Returns:

The modified set

Throws:

IllegalArgumentException - if either toModify or toConsider is null

mergeAvailableQueryAttributes

Set<String> mergeAvailableQueryAttributes(Set<String> toModify,
                                          Set<String> toConsider)

Modify the "toModify" argument in consideration of the "toConsider" argument. Return the resulting Set 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 set

toConsider - In consideration of this set

Returns:

The modified set

Throws:

IllegalArgumentException - if either toModify or toConsider is null

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
