Class TimeoutPolicy

java.lang.Object

org.eclipse.stardust.engine.api.query.TimeoutPolicy

All Implemented Interfaces:

Serializable, EvaluationPolicy

public class TimeoutPolicy
extends Object
implements EvaluationPolicy

Supports specification of a runtime constraint on query execution. If query execution exceeds the maximum time allowed, an ConcurrencyException will be reported.

Using timeouts might be useful to handle deadlock scenarios, i.e. to increase the probability of queries being rolled back instead of concurrently performed modifications.
