Class TimeAwareNodeEvaluator<T,V extends java.lang.Comparable<V>>

java.lang.Object

ai.libs.jaicore.search.algorithms.standard.bestfirst.nodeevaluation.TimeAwareNodeEvaluator<T,V>

Type Parameters:

T -

V -

All Implemented Interfaces:

ai.libs.jaicore.basic.ILoggingCustomizable, INodeEvaluator<T,V>

Direct Known Subclasses:

RandomCompletionBasedNodeEvaluator

public abstract class TimeAwareNodeEvaluator<T,V extends java.lang.Comparable<V>>
extends java.lang.Object
implements INodeEvaluator<T,V>, ai.libs.jaicore.basic.ILoggingCustomizable

This class can be used to create node evaluators with a time limit for the evaluation of each node. The remaining time for the evaluation of the node is given with the call of f. The thread will be interrupted after the timeout if it has not returned control in time.
