Interface ITopologicalSortErrorCallback<TValue>

Type Parameters:

TValue - The type of Object that this error callback will operate on.

public interface ITopologicalSortErrorCallback<TValue>

A callback for when an error has occurred during asynchronous processing.

Method Summary

void	handleError(TValue value, Throwable t, IVertex<TValue> vertex, ITopologicalSortCoordinator coordinator) The callback that will be executed inside a thread pool other than the one invoking the sort.

Method Detail

handleError

void handleError(TValue value,
                 Throwable t,
                 IVertex<TValue> vertex,
                 ITopologicalSortCoordinator coordinator)

The callback that will be executed inside a thread pool other than the one invoking the sort.

Parameters:

vertex - Instance of IVertex of type TVertex that produced the error. Could be null.

t - Exception that was thrown.

coordinator - Instance of ITopologicalSortCoordinator that allows for communication between asynchronous sorting submissions done by the driver (which is typically done by an instance of ITopologicalSortStrategy).
