Public Methods

public static EntityListConsumer<GenericValue, Map<String, String>> fromColumn (String columnName)

Consumer that returns a map of mixed-case usernames that were found from a columns(String) query to their lowercase equivalents. The column list must include the same columnName, but need not include any others.

The resulting map might, for example, have a key of "Fred" with a corresponding value of "fred".

public static EntityListConsumer<GenericValue, Map<String, List<Long>>> fromColumnAndReturnIds (String columnName)

Consumer that returns a map of lowercase versions of the mixed-case usernames that were found from a columns(String) query to a list of the associated entity IDs for the rows that contained a mixed-case username. The column list must include the same columnName and "id", but need not include any others.

The resulting map might, for example, have a key of "fred" with a corresponding value list of [10100, 10300, 10201, 10210, 10200]. The list should not be assumed to be in any particular order.

public static EntityListConsumer<String, Map<String, String>> fromStrings ()

Consumer that returns a map of mixed-case usernames that were found from a distinctString(String) query to their lowercase equivalents.
