All Implemented Interfaces:

Node

public class AndJoin
extends AbstractGateway

Gateway, that implements the "structured synchronizing merge" workflow pattern. That means, it synchronises (re-joins) the threads of execution that are originating from the paired AndFork or OrFork. Only when all threads of execution arrived at the AndJoin, execution continues along the subsequent branch.

The underlying token model restricts the usage of AndJoins to be in balanced pairs with AndFork or OrForks.

Method Detail

execute

public void execute(GraphEngine engine,
                    Token token)

Description copied from interface: Node

Performs node specific logic. Either from the execute method, or later from the outside, the GraphEngineFacade#complete(WorkItem) method must be called to continue executing the GraphInstance.

Parameters:

engine - the GraphEngine which is performing the execution

token - the Token which is currently executing in this node

cancel

public void cancel(GraphEngine engine,
                   Token token)

Description copied from interface: Node

Called when the GraphEngine cancels the execution of a Token, that is currently pointing to this node and is in a wait state.

Parameters:

engine - the GraphEngine which is performing the execution

token - the Token pointing to this node
