setTimerService

public void setTimerService(TimerService svc)

doStart

public boolean doStart(NodeContext ctx)
Description copied from class: BaseNodeImpl
Default implementation of doStart() - just returns true to allow the processing to continue

Specified by:
doStart in interface Node
Overrides:
doStart in class BaseNodeImpl
Parameters:
ctx - execution context for this node
Returns:
true if MessageProcess automatically continues exection of the instance, or false if not

doEnd

public Connection[] doEnd(NodeContext ctx)
Description copied from interface: Node
Second 'work method' for a node, called after doStart(). This method should do any post action (task, timer, etc) cleanup and then make a decision among the possible connections which connection (or connections, in the case of a node that forks) should be transversed.

Returns:
one or more connections to transverse, or null if processing for this instance should stop
