All Implemented Interfaces:
Serializable, Comparable<Pop>, Constable

public enum Pop extends Enum<Pop>
A Path 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 that mixed will return results as a list if there are multiple (like all) or as a singleton if only one object in the path is labeled (like last).
