Class BeanAsyncCallActivity

java.lang.Object

ee.telekom.workflow.graph.node.AbstractNode

ee.telekom.workflow.graph.node.activity.BeanAsyncCallActivity

All Implemented Interfaces:

Node

public class BeanAsyncCallActivity
extends AbstractNode

Activity, pausing execution until a task (call of method on a bean with given name) has been completed. The task is executed asynchronously by an external system.

Method Summary

Modifier and Type	Method and Description
void	cancel(GraphEngine engine, Token token) Called when the GraphEngine cancels the execution of a Token, that is currently pointing to this node and is in a wait state.
void	execute(GraphEngine engine, Token token) Performs node specific logic.
ArrayMapping	getArgumentsMapping()
String	getBean()
String	getMethod()
OutputMapping	getResultMapping()
void	store(Environment environment, Object result) When a token execution on a node completes and returns control back to the engine, then the engine mandates the node to store the node execution result into the graph instance's environment.

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

store

public void store(Environment environment,
                  Object result)

Description copied from interface: Node

When a token execution on a node completes and returns control back to the engine, then the engine mandates the node to store the node execution result into the graph instance's environment.

Parameters:

environment - the environment to store the result in

result - the result to be stored
