com.graphhopper.jsprit.core.algorithm.listener.events.StrategyExecuted

Record Components:

iteration - The iteration number

timestamp - When the strategy completed execution

strategyId - The full strategy ID including operator names

All Implemented Interfaces:

AlgorithmEvent

public record StrategyExecuted(int iteration, long timestamp, String strategyId)
extends Record
implements AlgorithmEvent

Emitted after a strategy has been executed (ruin and insertion completed).

This event provides the strategy ID that was used in the current iteration. For independent selection, this will be an expressive name like "independent:radial+regretFast". For legacy strategies, it will be the coupled strategy name like "radial_regret".

Constructor Details

StrategyExecuted

public StrategyExecuted(int iteration,
 long timestamp,
 String strategyId)

Creates an instance of a StrategyExecuted record class.

Parameters:

iteration - the value for the iteration record component

timestamp - the value for the timestamp record component

strategyId - the value for the strategyId record component

Method Details

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with '=='.

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

iteration

public int iteration()

Returns the value of the iteration record component.

Specified by:

iteration in interface AlgorithmEvent

Returns:

the value of the iteration record component

timestamp

public long timestamp()

Returns the value of the timestamp record component.

Specified by:

timestamp in interface AlgorithmEvent

Returns:

the value of the timestamp record component

strategyId

public String strategyId()

Returns the value of the strategyId record component.

Returns:

the value of the strategyId record component
