Method Detail

extractTopKFromMap

@Generated(value="src/python/synchronize.py")
public <V extends Comparable<V>> void extractTopKFromMap(PgxMap<PgxVertex<ID>,V> map,
                                                               int k)
                        throws ExecutionException,
                               InterruptedException

Blocking version of #extractTopKFromMapAsync(). Calls #extractTopKFromMapAsync() and waits for returned PgxFuture to complete.

Throws:

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

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

extractTopKFromMapAsync

public <V extends Comparable<V>> PgxFuture<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

toString

public String toString()

Overrides:

toString in class VertexCollection<ID extends Comparable<ID>>
