Method Detail

getLabelAsync

public PgxFuture<java.lang.String> getLabelAsync()

Gets the label.

Returns:

the edge label.

Throws:

java.lang.IllegalStateException - if this graph does not have any labels.

getSourceAsync

public <ID> PgxFuture<PgxVertex<ID>> getSourceAsync()

Gets the source vertex.

Returns:

the source vertex.

getDestinationAsync

public <ID> PgxFuture<PgxVertex<ID>> getDestinationAsync()

Gets the destination vertex.

Returns:

the destination vertex.

getVerticesAsync

public <ID> PgxFuture<Pair<PgxVertex<ID>,PgxVertex<ID>>> getVerticesAsync()

Gets both vertices of this edge as a pair. In the directed case, the first part of the pair is the source and the second one the destination vertex.

Returns:

the source and the destination vertex as a pair

getLabel

public java.lang.String getLabel()

Blocking version of getLabelAsync(). Calls getLabelAsync() and waits for the returned PgxFuture to complete.

getSource

public <ID> PgxVertex<ID> getSource()

Blocking version of getSourceAsync(). Calls getSourceAsync() and waits for the returned PgxFuture to complete.

getDestination

public <ID> PgxVertex<ID> getDestination()

Blocking version of getDestinationAsync(). Calls getDestinationAsync() and waits for the returned PgxFuture to complete.

getVertices

public <ID> Pair<PgxVertex<ID>,PgxVertex<ID>> getVertices()

Blocking version of getVerticesAsync(). Calls getVerticesAsync() and waits for the returned the returned PgxFuture to complete.
