Interface MutationStatListener

public interface MutationStatListener

MutationStatsListener uses the listener pattern to provide a flexible way of accessing statistics about each run. Models which require statistics about mutation operations throughout a run would typically implement this interface. GPAbstractModel already provides an implementation. There are 2 steps to using this interface to gain access to mutation statistics.

• Implement getMutationStatFields() to return an array of the MutationStatFields required, in the order desired.
• Implement mutationStats(Object[]) which will receive these statistics in that order to use them however required - print to screen, file, etc.

Method Summary

MutationStatField[]	getMutationStatFields() The implementing class must return an array of fields which the listening objects are interested in listening to.
void	mutationStats(java.lang.Object[] stats) This method will be called after every run completes with an array containing the statistics requested with getMutationStatFields().

Method Detail

getMutationStatFields

MutationStatField[] getMutationStatFields()

The implementing class must return an array of fields which the listening objects are interested in listening to. The values for each of the fields this method returns will be given as part of the stats array passed to the mutationStats(Object[]) array.

mutationStats

void mutationStats(java.lang.Object[] stats)

This method will be called after every run completes with an array containing the statistics requested with getMutationStatFields().

Parameters:

stats - An array of statistics relating to the last run completed. The order of the array will match the order that the fields were requested in the return of getMutationStatFields() method. The array is of type Object[] but the dynamic type of each element will vary depending on the field. For information of types view the comments on the stats fields.
