public enum Pop extends Enum<Pop>
APath
may have multiple values associated with a single label.Pop
is used to determine whether the first value, last value, or all values are gathered. Note thatmixed
will return results as a list if there are multiple (likeall
) or as a singleton if only one object in the path is labeled (likelast
).- Author:
