Method Detail

getDestination

public <ID> PgxVertex<ID> getDestination()
                                  throws java.util.concurrent.ExecutionException,
                                         java.lang.InterruptedException

Blocking version of getDestinationAsync(). Calls getDestinationAsync() and waits for the 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.

getDestinationAsync

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

getLabel

public java.lang.String getLabel()
                          throws java.util.concurrent.ExecutionException,
                                 java.lang.InterruptedException

Blocking version of getLabelAsync(). Calls getLabelAsync() and waits for the 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.

getLabelAsync

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

Gets the label.

Returns:

the edge label. null if no label for this edge exists.

Throws:

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

getSource

public <ID> PgxVertex<ID> getSource()
                             throws java.util.concurrent.ExecutionException,
                                    java.lang.InterruptedException

Blocking version of getSourceAsync(). Calls getSourceAsync() and waits for the 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.

getSourceAsync

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