Enum Pop

  • All Implemented Interfaces:
    Serializable, Comparable<Pop>
    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).

      • all

        public static final Pop all
        Get all the items and return them as a list.

    • Method Detail

      • values

        public static Pop[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows: 
        for (Pop c : Pop.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static Pop valueOf​(String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        IllegalArgumentException - if this enum type has no constant with the specified name
        NullPointerException - if the argument is null
