Class ValidateFieldResult<T>

java.lang.Object

com.conveyal.gtfs.loader.ValidateFieldResult<T>

public class ValidateFieldResult<T>
extends Object

This mini helper class is used during feed loading to return both: - a cleaned value of arbitrary type T and - any errors encountered while validating the original value. Previously we resorted to returning a single validated value and throwing exceptions if bad values were encountered, but this kept us from being able to do both things at once: repair the value AND collect errors on the offending input.
