Creates an instance that will use the provided function to uniquely identify results and that will expect as many total results as indicated by the query.

Parameters:

maker - a key-making function

query - an indication of how many results are required

with

public static <T,K extends Comparable<? super K>> ResultsAggregator<T> with(Function<? super T,? extends K> maker,
                                                                            int startIndex,

                                                                            boolean merge)

forUsers

public static <T extends User> ResultsAggregator<T> forUsers(int startIndex,
                                                             int maxResults)

Creates an aggregator that will identify and sort users by lower-cased name.

Parameters:

startIndex - defines how many results should be skipped

maxResults - maximum number of results to be returned

with

public static <T> ResultsAggregator<T> with(Query<T> query)

Creates an instance that will sort, de-duplicate and constrain results according to the query.

with

public static <T> ResultsAggregator<T> with(Query<T> query,
                                            boolean merge)
