## Enum Pop

- java.lang.Object
- - java.lang.Enum<Pop>
  - - org.apache.tinkerpop.gremlin.process.traversal.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`).

    - #### first

          public static final Pop first

      The first item in an ordered collection (i.e. `collection[0]`).
      Since:
        3.0.0-incubating

    - #### last

          public static final Pop last

      The last item in an ordered collection (i.e. `collection[collection.size()-1]`).
      Since:
        3.0.0-incubating

    - #### all

          public static final Pop all

      Get all the items and return them as a list.
      Since:
        3.0.0-incubating

    - #### mixed

          public static final Pop mixed

      Get the items as either a list (for multiple) or an object (for singles).

  - ### 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
