Interface ITopologicalSortCallback<TValue,TProcessedValue>

Type Parameters:

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

public interface ITopologicalSortCallback<TValue,TProcessedValue>

A callback for when a vertex has been found in topological order. Allows for parallel vertex processing unless one is found that is waiting for processing of 1 or more transitive vertices. In this case, processing will not proceed until the transitive vertices have completed their work.

Method Summary

TProcessedValue

handle(TValue value, ITopologicalSortInput<TValue,TProcessedValue> input, IVertex<TValue> vertex, ITopologicalSortCoordinator coordinator) The callback that will be executed inside a thread other than the one invoking the sort.

Method Detail

handle

TProcessedValue handle(TValue value,
                       ITopologicalSortInput<TValue,TProcessedValue> input,
                       IVertex<TValue> vertex,
                       ITopologicalSortCoordinator coordinator)
                       throws Throwable

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

Parameters:

vertex - Instance of IVertex that can now be processed.

input - Instance of ITopologicalSortInput that provides the in-degree outputs of directly dependent vertices.

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).

Throws:

Throwable
