Method Detail

extractTopKFromMap

public <V extends java.lang.Comparable<V>> void extractTopKFromMap(PgxMap<PgxVertex<ID>,V> map,
                                                                   int k)

Blocking version of extractTopKFromMapAsync(PgxMap, int). Calls extractTopKFromMapAsync(PgxMap, int) and waits for returned PgxFuture to complete.

extractTopKFromMapAsync

public <V extends java.lang.Comparable<V>> PgxFuture<java.lang.Void> extractTopKFromMapAsync(PgxMap<PgxVertex<ID>,V> map,
                                                                                             int k)

Extracts the top k keys from the given map and puts them into this collection.

Parameters:

map - the map to extract the keys from

k - how many keys to extract
