Method Detail

extractTopKFromMap

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

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

Throws:

java.lang.InterruptedException - if the caller thread gets interrupted while waiting for completion.

java.util.concurrent.ExecutionException - if any exception occurred during asynchronous execution. The actual exception will be nested.

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
