public enum GenerationStatField
extends java.lang.Enum<GenerationStatField>

This enum gives all the available generation statistics that can be requested. Generation statistics are those statistics that are generated at the end of each generation. Each GenStatField has a datatype related to it which is the type which the data will be returned in.
